Executive Summary
Built in 1899, Cape Sorell Lighthouse is a historic site recognised by both the Commonwealth and the State Government of Tasmania. The place was put on the Commonwealth Heritage List in 2004 for its contribution to the development of navigational aids along the west coast of Tasmania, and for its standing as the only remaining intact structure of the Cape Sorell Lightstation complex. The Lighthouse is also recognised for its illustration of a type of late-nineteenth-century lighthouse, and its prominence within its landscape setting.
Cape Sorell Lighthouse is listed on the Tasmanian State Heritage Register for its contribution to the development of navigation aids along the west coast of Tasmania, its standing as an example of a Victorian brick lighthouse—the only remaining intact structure of the Cape Sorell Lightstation complex—, and its aesthetic prominence in its landscape setting.
The Lighthouse is situated along the western coast of Tasmania at the mouth of Macquarie Harbour, approximately 12km south-west of the township of Strahan. Once a large complex comprising of the tower, an engine room, and three keepers’ cottages, the lighthouse tower remains the only intact structure onsite.
Originally fitted with a 2nd Order dioptric light with a four-wick trinity burner, the tower is now fitted with a Vega VRB beacon operating on an automated mechanism as part of AMSA’s network of aids to navigation (AtoN). The equipment is serviced by AMSA’s maintenance contractor who visits at least once per year. AMSA’s officers visit on an ad hoc basis for auditing, project and community liaison purposes.
This heritage management plan is concerned primarily with the lighthouse; however it also addresses the management of the surrounding land. The plan is intended to guide AMSA’s decisions and action. AMSA has prepared this plan to integrate the heritage values of the lighthouse in accordance with the Environment Protection and Biodiversity Conservation Act 1999 Cth (EPBC Act) and the Environment Protection and Biodiversity Conservation Regulations 2000 Cth (EPBC Regulations).
Well-built and generally well-maintained, the lighthouse is in relatively good, stable condition. The policies and management guidelines set out in this heritage management plan strive to ensure the Commonwealth heritage values of Cape Sorell Lighthouse are recognised, maintained and preserved for future generations.
The Australian Maritime Safety Authority (AMSA) is the Commonwealth agency responsible for coastal aids to navigation (AtoN). AMSA’s network includes Cape Sorell Lighthouse built in 1899.
Section 341S of the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) requires AMSA to prepare a management plan for Cape Sorell Lighthouse that addresses the matters prescribed in Schedules 7A and 7B of the Environment Protection and Biodiversity Conservation Regulations 2000 (Cth) (EPBC Regulations). The principal features of this management plan are:
AMSA has prepared this heritage management plan to guide the future conservation of the place. This plan provides the framework and basis for the conservation and best practice management of Cape Sorell Lighthouse in recognition of its heritage values. The policies in this plan indicate the objectives for identification, protection, conservation and presentation of the Commonwealth heritage values of the place. Figure 2 shows the basic planning process applied.

1.2 Heritage management plan objectives
The objectives of this heritage management plan are to:
In undertaking these objectives, this plan aims to:
The organisational planning cycle and associated budgeting process is used to confirm requirements, allocate funding and manage delivery of maintenance activities. Detailed planning for the AtoN network is managed through AMSA’s internal planning processes.
An interactive map showing many of AMSA’s heritage sites, including Cape Sorell Lighthouse, can be found at AMSA Heritage Lighthouses Interactive MapP0FP0F[1]PP.
1.3 Methodology
The methodology used in the preparation of this plan is consistent with the recommendations of The Burra Charter and with the requirements of Chapter 5, Part 15 Division 1A of the EPBC Act. In particular, the plan:
The criterion set out at Schedule 7A (h) (i-xiii) informed the development of the required policies for the management of Cape Sorell Lighthouse, in conjunction with input from the Department of Climate Change, Energy, the Environment and Water (DEECCW) on best practice management.
Consultation
In the process of preparing the plan, AMSA engaged with the Tasmanian Parks and Wildlife Service who provided general feedback on the plan. AMSA sought engagement with the Aboriginal Land Council of Tasmania and the Tasmanian Aboriginal Centre (Burnie Office) under the direction of the Department of Primary Industries, Parks, Water and Environment Tas (Aboriginal Heritage Tasmania). A response is yet to be received, and this section will be updated to reflect progress with these consultations.
The draft management plan was advertised in accordance with the EPBC Act and EPBC Regulations. On 4 May 2022 a notice was placed in The Australian newspaper publication which invited the general public to review the draft plan on AMSA’s website and provide feedback. Public consultation closed on 1 June 2022. No submissions were received.
A developed draft was submitted to the Federal Minister through the Heritage Branch of the Department of Climate Change, Energy, the Environment and Water (DCCEEW), and in that process the Minister’s delegate sought advice from the Australian Heritage Council. The plan was endorsed on 18 July 2023.
1.4 Status
This plan has been adopted by AMSA in accordance with Schedule 7A (Management plans for Commonwealth Heritage places) and Schedule 7B (Commonwealth Heritage management principles) of the EPBC Regulations to guide the management of the place and for inclusion in the Federal Register of Legislative Instruments.
1.5 Authorship
This plan has been prepared by AMSA. At the initial time of publication, the Australian Maritime Systems Group (AMSG) is the contracted maintenance provider for the Commonwealth Government’s AtoN network including Cape Sorell Lighthouse.

3. History
3.1 General history of lighthouses in Australia
The first lighthouse to be constructed on Australian soil was Macquarie Lighthouse, located at the entrance to Port Jackson, NSW. First lit in 1818, the cost of the lighthouse was recovered through the introduction of a levy on shipping. This was instigated by Governor Lachlan Macquarie, who ordered and named the light.
The following century oversaw the construction of hundreds of lighthouses around the country. Constructing and maintaining a lighthouse were costly ventures that often required the financial support of multiple colonies. However, they were deemed necessary aids in assisting the safety of mariners at sea. Lighthouses were firstly managed by the colony they lay within, with each colony developing their own style of lighthouse and operational system. Following Federation in 1901, which saw the various colonies unite under one Commonwealth government, lighthouse management was transferred from state hands to the Commonwealth Lighthouse Service.
Lamps and optics: an overview
Lighthouse technology has altered drastically over the centuries. Eighteenth century lighthouses were lit using parabolic mirrors and oil lamps. Documentation of early examples of parabolic mirrors in the United Kingdom, circa 1760, were documented as consisting of wood and lined with pieces of looking glass or plates of tin. As described by Searle, ’When light hits a shiny surface, it is reflected at an angle equal to that at which it hit. With a light source is placed in the focal point of a parabolic reflector, the light rays are reflected parallel to one another, producing a concentrated beam’.[8]

Figure 10. Dioptric lens on display at Narooma (Source: AMSA)
In 1822, Augustin Fresnel invented the dioptric glass lens. By crafting concentric annular rings with a convex lens, Fresnel had discovered a method of reducing the amount of light absorbed by a lens. The Dioptric System was adopted quickly with Cordouran Lighthouse (France), which was fitted with the first dioptric lens in 1823. The majority of heritage-listed lighthouses in Australia house dioptric lenses made by others such as Chance Brothers (United Kingdom), Henry-LePaute (France), Barbier, Bernard & Turenne (BBT, France) and Svenska Aktiebolaget Gasaccumulator (AGA of Sweden). These lenses were made in a range of standard sizes, called orders—see ‘Appendix 2. Glossary of lighthouse Terms relevant to Cape Sorell Lighthouse’.
Early Australian lighthouses were originally fuelled by whale oil and burned in Argand lamps, and multiple wicks were required in order to create a large flame that could be observed from sea. By the 1850s, whale oil had been replaced by colza oil, which was in turn replaced by kerosene, a mineral oil.
In 1900, incandescent burners were introduced. This saw the burning of fuel inside an incandescent mantle, which produced a brighter light with less fuel within a smaller volume. Light keepers were required to maintain pressure to the burner by manually pumping a handle as can be seen in Figure 9.
In 1912, Swedish engineer Gustaf Dalén, was awarded the Nobel Prize in physics for a series of inventions relating to acetylene-powered navigation lights. Dalén’s system included the sun valve, the mixer, the flasher, and the cylinder containing compressed acetylene. Due to their efficiency and reliability, Dalén’s inventions led to the gradual destaffing of lighthouses. Acetylene was quickly adopted by the Commonwealth Lighthouse Service from 1915 onwards.
Figure 11. Dalén's system - sunvalve, mixer and flasher (Source: AMSA)
Large dioptric lenses, such as that shown in Figure 10, gradually decreased in popularity due to cost and the move towards unmanned automatic lighthouses. By the early 1900s, Australia had stopped ordering these lenses with the last installed at Eclipse Island in Western Australia in 1927. Smaller Fresnel lenses continued to be produced and installed until the 1970s when plastic lanterns, still utilising Fresnel’s technology, were favoured instead. Acetylene remained in use until it was finally phased out in the 1990s.
In the current day, Australian lighthouses are lit and extinguished automatically using mains power, diesel generators, and solar-voltaic systems.
3.2 The Commonwealth Lighthouse Service
When the Australian colonies federated in 1901, they decided that the new Commonwealth government would be responsible for coastal lighthouses—that is, major lights used by vessels travelling from port to port—but not the minor lights used for navigation within harbours and rivers. There was a delay before this new arrangement came into effect. Existing lights continued to be operated by the states.
Since 1915, various Commonwealth departments have managed lighthouses. AMSA, established under the Australian Maritime Safety Authority Act 1990 (Cth), is now responsible for operating Commonwealth lighthouses and other aids to navigation, along with its other functions.

3.4 Cape Sorell: a history
Aboriginal history
The full extent of past and present Aboriginal cultural associations with Cape Sorell requires further consultation and research. New information will be included in later versions of this plan.
Early European history
Cape Sorell was named after William Sorell, Lieutenant-Governor of Tasmania (1817–1824). Sorell was renowned in the Macquarie Harbour region along the west coast of Tasmania.
Owing to its isolated position, very little European contact with the region was made early on. Macquarie Harbour, however, was recorded by European expeditions in 1815 and was later established as a penal station in 1822. Ships bringing in convicts and supplies bound for the penal station would round Cape Sorell in order to enter the harbour. The port of Strahan was established following the closure of the penal station and remained a major port of call for the timber industry until the establishment of a railway line.[9]
3.5 Building a lighthouse
Why Cape Sorell?
Cape Sorell sits as the outermost boundary of the nearby Macquarie Harbour. Its position served as a critical orientation point for shipping entering and exiting the harbour and its associated ports. Nautical merchants trading along the west Tasmanian coast strongly advocated for the construction of a light in order to assist the safe passage of goods and crew.[10] Due to the Cape’s extended position and the harbour’s hidden location, Cape Sorell was a prime location for a lighthouse as it could assist ships navigating both the coastline and the entrance to the harbour.
The site chosen was approximately half a mile inland on quartzite rock and approximately 1,400 acres in size. Another site had been considered on the cape, further inland and higher in elevation. However it was decided constructing a lighthouse so far from the sea ‘would impair the efficiency’.[11]
Design
Blueprints for a lighthouse were prepared by the Hobart Marine Board’s architects, Huckson and Hutcheson. On 11 March 1898, these plans were submitted by the Minister for Lands and Works and were swiftly approved by the Executive Council.[12]
The designs depicted a 40-meter tall lighthouse tower constructed of brick, accompanied by keepers’ quarters for a master and assistant masters.[13] The estimated cost was £6243 for the building and £2307 for the lantern and light. On 9 May 1898, The Mercury reported Chance Bros. & Co. Birmingham had been contacted and were to provide a light suitable for Cape Sorell.[14]
Construction
Following finalisation of the design, tenders were called and the construction of Cape Sorell Lighthouse was awarded to the Duff Bros. and their tender of £5580.[15] The project’s progress was reported in the Zeehan and Dundas Herald:
Mr R. Duff, of Duff Bros., Hobart, contractors for the building of the lighthouse at Cape Sorell, arrived on Zeehan yesterday. The lighthouse is situated some two miles from Macquarie entrance, and is so located that it will prove a convenience to vessels trading either from the North or South. The tower, when completed, will be 100ft high from the foundation, which is of cement built on the solid reef. Nearly 400,000 bricks will be used in the building of the tower, made at Messers Duff Bros. works, New Town. At the base the lighthouse measures 40ft, and is cemented for 30ft. The light will show for a distance of 20 miles. and will be over 200ft above water level. Two brick five-roomed cottages have been built for assistants, and an either-roomed brick residence is now in course of construction for the head keeper. The tower is completed for 70ft, and the contractors expect to finish the work some time next month.[16]
A wooden tramway was laid down from Pilot Bay to the construction site, approximately 1.5 miles (2.4 km) apart, upon which building materials were transferred to and from the site.[17] On 28 February 1899, the Tasmanian News reported that the R.M.S. Papanui, which was carrying Cape Sorell’s lamp, had arrived from London and its installation was to be instantaneous.[18]
Construction was completed in May 1899 and an opening ceremony was held on 2 October the same year. This ceremony was performed by Captain J. W. Evans, M.H.A., Master Warden of the Hobart Marine Board. The ceremonial party also consisted of Strahan and Hobart Marine Board members.[19]
Equipment when built
Upon completion, the Cape Sorell Lighthouse stood as a 40-metre brick structure, fitted with a Chance Bros & Co. 2nd Order dioptric light, which was fuelled by vaporised kerosene and composed of alternating white and red flashes every 22.5 seconds. In good weather the visibility of the white flash, with an intensity of 208,000 candlepower, allegedly reached 20 miles (32km). The red flash, with an intensity of 83,000 candlepower, reached 12 miles (19km) in distance. The light originally rotated by weights, pulleys and ropes. The lamp installed was regarded as a ‘Piston Pressure Lamp’ which fed a four-wick Trinity burner.[20]
The tower was accompanied by an engine room, three cottages for the assistant keepers and Superintendent stationed at the light.[21] Cape Sorell was the last lighthouse to be built by the Tasmanian Government before Commonwealth authorities assumed responsibility for coastal lights in 1915.
Figure 12. Tramline leading to Cape Sorell Light c. 1900 (Digitised item from: W.L. Crowther Library, Tasmanian Archive and Heritage Office)
3.6 Lighthouse keeping
Cape Sorell Lighthouse was originally attended by William Jacques and his assistants Carlson and Light. The keepers were required to tend to the light in shifts and maintain the cottages, tower and engine room. A supply vessel would visit each week to replenish the lighthouse’s stores, and maintenance technicians could access the site via horse-drawn truck along the wooden rails leading to the lighthouse from Pilot Beach.
A total of three keepers remained stationed on site until 1962 when the lighthouse was converted to diesel-electric operation and the number of keepers reduced. In 1971, the lighthouse was converted to automatic operation. The remaining keepers were withdrawn and the keepers’ cottages demolished.

3.8 Changes and conservation over time
The Cape Sorell Lighthouse underwent a number of changes over the decades since its construction—most significantly the conversion of the main light to solar power in the 1980s.
The Brewis Report
Commander CRW Brewis, retired naval surveyor, was commissioned in 1911 by the Commonwealth Government to report on the condition of existing lights and to recommend any additional ones. Brewis visited every lighthouse in Australia between June and December 1912, and produced a series of reports published in their final form in March 1913. These reports were the basis for future decisions made for the management of individual lighthouses.
Recommendations made by Brewis for Cape Sorell Lighthouse included alteration of the light’s character, an increase to the light’s intensity, and the installation of a 55mm incandescent mantle and telephone communications.[24]
CAPE SORELL LIGHT. (78 miles from West Point.) Lat. 42º 11’ S., Long. 145º 10’ E., Chart No. 1079.- Established in the year 1899. Lloyd’s Signal Station. Not connected by telephone. Character.- One flashing white and red alternately every 22 ½ seconds. Dioptric, 2nd Order.- White, 20,000 c.p.; red, 5,000 c.p. White, visible, in clear weather, 20 nautical miles; red, 12 miles. Brick tower, 100 feet. Height of focal plane, 186 feet above high water. Condition and State of Efficiency.- The light-house tower, and apparatus are in good condition. The red flash in the light impairs its brilliancy. Red being the colour of danger, uniformity would be secured if the alternate red flash were discontinued. The dwellings are in fair order, with the exception that the roofs and spouting are in need of repair. The wooden tramway also requires extensive renewals. Communication.- The Pilot Station at Macquarie Heads is connected with Strahan by telephone. The distance from the heads to Cape Sorell by beach and tramway is about 3 miles, and in a direct line about 2.4 miles. No proposal has been considered for connecting Cape Sorell by telephone, but there are no difficulties in the way. At present messages of an urgent nature are telephoned to the heads, and conveyed to Cape Sorell by messenger. RECOMMENDED.- (a) The red flashes be discontinued, converting the character of the light to one white, with red sector, flashing. Flash, three seconds duration every 22 ½ seconds. Red, visible from N. 25º W. to N. over Sloop Rocks. White elsewhere. (b) The power of the light be increased from 20,000 to 120,000 c.p., and economy effected in the consumption of oil by installing a 55 mm. incandescent mantle; illuminant, vaporized kerosene. (c) Telephone communication be established. |
Alteration to the light
The following table details alterations made to the light at Cape Sorell over the course of the lighthouse’s history.

3.9 Summary of current and former uses
From its construction in 1899, Cape Sorell Lighthouse has been used as a marine AtoN for mariners at sea. Its AtoN capability remains its primary use.
3.10 Summary of past and present community associations
Aboriginal associations
Further consultation with Traditional Custodians is required for a greater understanding of the past and present associations held across the region.
The Department of Primary Industries, Parks, Water and Environment (Aboriginal Heritage Tasmania) advised there are a number of Aboriginal heritage sites recorded nearby the lighthouse.
Local, national and international associations
The manned history of the lighthouse has resulted in familial associations with the place locally, nationally and internationally. Cape Sorell is considered a significant site of Tasmanian maritime history.
3.11 Unresolved questions or historical conflicts
Any historical conflicts or unresolved questions brought to light will be addressed here in future versions of this plan.
3.12 Recommendations for further research
Research on past lighthouse keepers of Cape Sorell Lighthouse may be beneficial in determining the full extent of the social value placed on the site within the surrounding communities.

4. Fabric
4.1 Fabric register
The cultural significance of the lighthouse resides in its fabric and in its intangible aspects, such as the meanings people ascribe to it, and its connections to other places and things. The survival of its cultural value depends on an understanding of what is significant and on clear thinking about the consequences of change. The Burra Charter sets out good practice for conserving places of cultural significance in Australia.
Criterion listed under ‘Heritage significance’ refers to the criterion satisfied within the specific Commonwealth heritage listing (see section 5.1).

4.3 Comparative analysis
Although significantly shorter, Table Cape Lighthouse shares a number of similarities with Cape Sorell. Table Cape Lighthouse, located along the northern coast of Tasmania, was constructed in 1888 and is composed of brick and masonry. Like Cape Sorell, Table Cape was also designed by Huckson & Hutchison and similarly fitted with a 2nd Order Chance Bros. light.

5. Heritage significance
5.1 Commonwealth Heritage listing – Cape Sorell Lighthouse
The following information is taken from the Cape Sorell Lighthouse listing on the Australian Heritage Database (Place ID: 105597).
Commonwealth statement of significance
Cape Sorell Lighthouse, built in 1899, is significant for its associations with the development of navigational aids along the west coast of Tasmania, and is the only remaining intact structure in a lightstation complex that included the tower, three keepers’ residences and an engine room. Remnant foundations serve to indicate the location of the former residences. (Criteria A.4 and B.2) (Themes: 3.8.1 Shipping to and from Australian ports, 3.16.1 Dealing with hazards and disasters).
In its general configuration, form and massing, the tower is illustrative of one of the types of lighthouses constructed around the continent during the latter part of the 19th century. (Criterion D.2)
The lighthouse, situated on the tip of the outermost boundary of Macquarie Harbour, in a rugged and lonely coastal setting, and being a very prominent structure in that landscape, has strong aesthetic values. (Criterion E.1)
Commonwealth heritage criteria
There are nine criteria for inclusion in the Commonwealth Heritage List—meeting any one of these is sufficient for listing a place. These criteria are similar to those used in other Commonwealth, state and local heritage legislation, although thresholds differ. In the following sections, the Cape Sorell Lighthouse is discussed in relation to each of the criteria as based on the site’s current Commonwealth Heritage Listing (Place ID: 105597).
Criterion | Relevant Attributes Identified | Explanation |
Criterion B – Rarity
This criterion is satisfied by places that have significant heritage value because of [their] possession of uncommon, rare or endangered aspects of Australia’s natural or cultural history. |
The whole tower, its prominence within the coastal landscape plus the footings of three former residences and an engine room. |
Cape Sorell Lighthouse, is the only remaining intact structure in its lightstation complex that included the tower, three keepers’ residences and an engine room. Remnant foundations serve to indicate the location of the former residences.
|
Criterion D – Characteristic values
This criterion is satisfied by places that have significant heritage values because of [their] importance in demonstrating the principal characteristics of a class of Australia’s natural or cultural history.
|
The tower’s form and massing. |
In its general configuration, form and massing, the tower is illustrative of one of the types of lighthouses constructed around the continent during the latter part of the 19th century. |
Criterion E – Aesthetic values
This criterion is satisfied by places that have significant heritage value because of [their] importance in exhibiting particular aesthetic characteristic value by a community or cultural group.
|
The lighthouse’s prominence within its coastal setting. |
The lighthouse, situated on the tip of the outermost boundary of Macquarie Harbour, in a rugged and lonely coastal setting, and being a very prominent structure in that landscape, has strong aesthetic values.

5.2 TAS State Heritage Register – Cape Sorell Lighthouse
The following information is taken directly from the Cape Sorell Lighthouse listing on the Tasmanian Heritage Register (THR ID: 5631).
TAS heritage statement of significance
No statement is provided for places listed prior to 2007.
TAS State heritage criteria
The Heritage Council may enter a place in the Heritage Register if it meets one or more of the following criteria from the Historic Cultural Heritage Act 1995 (Tas).
Criteria | Explanation/evidence
|
Criterion A – The place is important to the course or pattern of Tasmania’s history. | Cape Sorell Lighthouse, erected in 1899, is significant for its association with the development of navigational aids along the west coast of Tasmania, and is the only remaining structure in a light station complex that included the tower and three keepers’ residences.
|
Criterion D –The place is important in demonstrating the principal characteristics of a class of place in Tasmania’s history.
| Cape Sorell Lighthouse is of historic heritage significance because it represents the principal characteristics of a Victorian brick lighthouse. |
Criterion F –The place has a strong or special associations with a particular community or cultural group for social or spiritual reasons. | The lighthouse, situated on the tip of the outermost boundary of Macquarie Harbour, in a rugged and lonely coastal land and seascape setting, is of historic heritage significance as a dramatic landmark feature values by the community.
|
These heritage values, identified and explained in the Commonwealth Heritage List and the State Heritage Register, will form the basis of the management of Cape Sorell Lighthouse. In the event of necessary works, all criteria will be consulted to inform best practice management of the values associated with the lighthouse. See ‘Section 7. Conservation management principles and policies’ for further information on strategies to conserve heritage values of the Cape Sorell Lighthouse.
5.3 Condition and integrity of the Commonwealth heritage values
A heritage monitoring program was implemented in 2016. Each site is visited and reviewed every two years where the heritage fabric and values of the site are evaluated. Assessment of the condition and integrity of lighthouse's values are derived from the latest available ‘Heritage asset condition report’ produced by AMSA’s maintenance contractor.
Condition is measured on a Good – Fair – Poor scale and incorporates the current condition of the specific value. Integrity is measured on a High – Medium – Low scale which incorporates the value’s intactness.
Criteria | Values (including attributes) | Condition
| Integrity |
b) Rarity | Cape Sorell Lighthouse, is the only remaining intact structure in its lightstation complex that included the tower, three keepers’ residences and an engine room. Remnant foundations serve to indicate the location of the former residences.
The whole tower, its prominence within the coastal landscape plus the footings of three former residences and an engine room. | Good | High |
d) Characteristic values | In its general configuration, form and massing, the tower is illustrative of one of the types of lighthouses constructed around the continent during the latter part of the 19th century.
The tower’s form and massing.
| Good | High |
e) Aesthetic characteristics | The lighthouse, situated on the tip of the outermost boundary of Macquarie Harbour, in a rugged and lonely coastal setting, and being a very prominent structure in that landscape, has strong aesthetic values.
The lighthouse’s prominence within its coastal setting.
| Good | High |
As a whole, the heritage values of Cape Sorell Lighthouse are in good condition and considered to have high integrity. The tower remains intact with its configuration largely unchanged from its original design. It also maintains its standing as a prominent feature within the landscape.
5.4 Gain/loss of heritage values
As evidenced in Section 5.2, Cape Sorell Lighthouse’s identified Commonwealth Heritage values remain intact and in good condition.
In order to capture any gained Commonwealth Heritage values, a Heritage Place Review should be undertaken. At the time this plan was prepared, AMSA is planning a review program to be undertaken over a 5-year period.
Evidence for the potential gain or loss of heritage values will be documented within this section of future versions of this heritage management plan.
6. Opportunities and constraints
6.1 Implications arising from significance
The Commonwealth statement of significance (section 5.1 above) outlines that Cape Sorell Lighthouse is a place of considerable heritage value due to its associations with the development of navigational aids along the west coast of Tasmania.
The implication arising from this assessment is that key aspects of the place should be conserved to retain this significance. The key features requiring conservation include:
Referral and approvals of action
The EPBC Act requires approval from the Minister for the Environment for all actions likely to have a significant impact on matters of National Environmental Significance (NES).
The Act provides that the following actions require the approval of the Minister:
The definition of ‘environment’ in the EPBC Act and EPBC Regulations includes the cultural heritage values of places.
Heritage strategy
If an Australian Government agency owns or controls one or more places with Commonwealth heritage values, it must prepare a heritage strategy within two years from the first time they own or control the heritage place (section 341ZA).
A heritage strategy is a written document that integrates heritage conservation and management within an agency’s overall property planning and management framework. Its purpose is to help an agency manage and report on the steps it has taken to protect and conserve the commonwealth heritage values of the properties under its ownership or control.
The heritage strategy for AMSA’s AtoN assets was completed and approved by the Commonwealth Minister for the Environment in 2018 and reviewed in 2022. The latest version of the Strategy is available online.P37F[25]
Heritage asset condition report
A ‘heritage asset condition report’ is a written document that details the heritage fabric of a site with an in-depth description of each architectural and structural element. The document includes: a brief history of the site, the Commonwealth Heritage statement of significance and value criteria, a heritage significance rating for each individual element, and a catalogue of artefacts on-site. The document is also accompanied by up-to-date photos of each structural element. This document operates as a tool for heritage monitoring, and is reviewed and updated biennially.
Aboriginal heritage significance and natural values
Cape Sorell as a whole is notable for its Aboriginal heritage significance and natural values. Although these values lie outside of the Commonwealth heritage listing curtilage and AMSA’s lease, the potential remains for future works at the lighthouse to impact these values. At the time this plan was written, no plans have been made for future works at Cape Sorell Lighthouse. In the event major works at the lighthouse are to be carried out, AMSA will seek to minimise impacts to the surrounding area by:
6.2 Framework: sensitivity to change
Owing to the site’s rarity, configuration and aesthetic qualities, Cape Sorell Lighthouse is of high significance. Therefore, work actioned by AMSA on the lighthouse’s fabric harnesses the potential to reduce or eradicate the significance of the site’s heritage values.
Conservation works, including restoration and reconstruction, or adaption works of the absolute minimum so as to continue the lighthouse’s usefulness as an AtoN are the only works that should be actioned by AMSA on Cape Sorell Lighthouse. Some exceptions are made for health and safety requirements, however any and all work carried out must be conducted in line with heritage considerations and requirements of the EPBC Act.
The table below demonstrates the level of sensitivity attributed to the various elements of the fabric register in the face of change. These are measured on a High-Moderate-Low spectrum depending on the action’s possible threat to the site’s heritage values.
High sensitivity
High sensitivity to change includes instances where a change would pose a major threat to the heritage value of a specific fabric, or the lighthouse as a whole. A major threat is one that would lead to substantial or total loss of the heritage value.
Moderate sensitivity
Moderate sensitivity to change includes instances where a change would pose a moderate threat to the heritage value of a specific fabric, or to the heritage significance of a specific fabric in another part of the building. A moderate threat is one that would diminish the heritage value, or diminish the ability of an observer to appreciate the value.
Low sensitivity
Low sensitivity to change includes instances where a change would pose little or no threat to the heritage value of a specific fabric, or to the heritage significance in another part of the building.

6.4 Operational requirements and occupier needs
As a working AtoN, the operational needs of Cape Sorell Lighthouse are primarily concerned with navigational requirements. Below are the operational details and requirements of Cape Sorell Lighthouse as outlined by AMSA.
Navigation requirement for AMSA’s AtoN site
The following table is taken from AMSA’s Asset Management Strategy for the Cape Sorell light.
1 | Objective/rationale
| An AtoN is required at Cape Sorell to mark the cape itself and to provide a landfall mark for vessels entering Macquarie Harbour and Strahan. The AtoN is also required as a mark for coastal navigation for ships transiting the west coast of Tasmania. The AtoN further helps marking a number of unsurveyed areas both to its north-east and to its south.
|
2 | Required type(s) of AtoN
| A fixed structure is required to act as a day mark.
A distinctive light is required for use at night. |
3 | Priority/significance
| An AtoN at this site is useful for the navigation of commercial ships. |
4 | Required measure of performance | The service performance of the AtoN must comply with the IALA Availability Target Category 3 (97.0%). |
5
| Primary and secondary means (if any) of identification
| The day mark must be conspicuous. The existing 37-metre white masonry tower and lantern at an elevation of 51 metres meets this requirement. The light must comply with the requirements of rhythmic characters of light as per the IALA NAVGUIDE. The light must have distinct characteristics that are easy to recognise and identify. The present group flashing (2) white light every 15 seconds meets this requirement. |
6 | Visual range
| During daytime, the AtoN structure should be visible from at least five nautical miles. At night, the white light must have a nominal range of at least 17 nautical miles. |
7 | Radar conspicuousness
| As the Cape itself provides a good radar echo, no additional radar enhancement is required for this site. |
AMSA’s goals
AMSA is responsible, under the Navigation Act, for maintaining a network of marine AtoN around Australia’s coastline that assist mariners to make safe and efficient passages. AMSA’s present network of 500 marine AtoN includes traditional lighthouses such as Cape Sorell Lighthouse, beacons, buoys, racons, automatic identification system stations, metocean sensors including broadcasting tide gauges, current meter, directional wave rider buoys and a weather station.
Technological developments in the area of vessel traffic management have also contributed to increasing navigation safety and helped promote marine environment protection. AMSA aims to meet international standards for the reliability of lighthouses set by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA).
At the time of preparing this management plan, the major goal for Cape Sorell Lighthouse primarily encompassed continuing its utilisation as an AtoN (for as long as necessary), while upkeeping the appropriate maintenance to conserve and preserve the heritage values of the lighthouse.
Lighthouse performance standards
AMSA aims to meet international standards for the reliability of lighthouses set by IALA. Cape Sorell’s light is designated as an IALA Availability Category 3 AtoN (within a scale of Category 1 to Category 3, Category 1 aids are most critical). Category 3 aids have an availability target of 97 per cent.
Access to the lighthouse
One practical effect of this performance standard is that the operational equipment and structure of the light need to be kept in good condition so that equipment that fails in service is tended to quickly. Routine maintenance and emergency repairs are carried out by AMSA’s maintenance contractor. The contractor needs reliable access to the site for this work, and AMSA officers need access for occasional inspections of the site, including to audit the contractor’s performance.
6.5 Proposals for change
Preventative maintenance works are carried out on the lighthouse to maintain its status as a working marine AtoN, and to assist in the site’s conservation.
A list of scheduled preventative maintenance work is identified within the latest available site inspection report. The information provided below was taken from this report.
Maintenance | Estimated date of work |
Light lantern change | 2023 |
Lantern room paint | 2024 |
Structure paint | 2026 |
6.6 Potential pressures
A significant pressure that harnesses the potential to effect the Commonwealth’s heritage values of the place would be the obligation to remove or replace original fabric materials from the lighthouse due to unavoidable and irreversible deterioration. At the time this plan was written, no current plans have been made to remove or replace any original fabric materials from Cape Sorell Lighthouse. In the event plans are made to modify or remove original fabric, work will be conducted in line with the heritage considerations and requirements of the EPBC Act.
6.7 Processes for decision-making
Processes for decision-making are required in the event of an incident that impacts the heritage values of the site. The following incidents are included due to their likelihood of occurrence at Cape Sorell Lighthouse.
Incident | Procedure |
Major project/maintenance works proposed |
|
Damage to lighthouse’s fabric (heritage significance) |
|
Damage to lighthouse’s fabric (no heritage significance) |
|
Light upgrade |
|
Modification to lighthouse, such as adding of attachment |
|
Unforeseen discovery of Aboriginal artefacts on-site |
|
Divestment of lighthouse from AMSA |
|
7. Conservation management principles and policies
Policies
Note: The management of sensitive information is not relevant to AMSA’s heritage strategy and therefore bears no relevance in this management plan.
Fabric and setting
Policy 1 – Protect and conserve the significant external and internal fabric of the lightstation, including existing buildings, layout and setting.
AMSA’s main purpose is to facilitate the ongoing operation of the site as a marine AtoN while preserving the site’s heritage values. As part of a heritage monitoring program, Heritage Asset Condition Reports are produced for each site every two years to evaluate the condition of the heritage fabric and values. Routine servicing is also carried out by maintenance contractors. Regular written reports from these visits will be sent to AMSA Asset Management and Preparedness for review and any work requirements identified will be scheduled accordingly. Should for some unforeseen reason the site no longer be viable as a marine AtoN, ownership will be passed to an appropriate state or federal authority to ensure preservation of the heritage assets.
Implementation strategy:
Uses
Policy 2 – Install and operate equipment in the lighthouse, so it continues to function as an effective marine AtoN, in such a way as to impose the least possible harm to the significant fabric.
Cape Sorell Lighthouse’s use as a working marine AtoN is of high priority. Carrying out maintenance, including upgrades to AtoN equipment, is necessary to its function and continued marine safety along the TAS coast. In the event of the installation or upgrade to AtoN equipment, proper precaution will be taken to ensure the least possible harm is done to significant fabric.
Implementation strategy:
Policy 3 – Monitor possible impacts to the site resulting from tourism and control appropriate access to the lighthouse for contractors and visitors.
Cape Sorell Lighthouse is not currently open as a tourist site and access inside the lighthouse is restricted to authorised personnel, such as contractors and AMSA employees. AMSA personnel and contractors require easy access inside the lighthouse precinct and tower for periodical site visits to carry out inspections and routine maintenance.
Implementation strategy:
Interpretation
Policy 4 – Accurate and relevant interpretation of the history and significance of the place should be made available to site users/visitors and for offsite external research.
AMSA will continue to make information available through the maintenance of site interpretive signage and its website.
Implementation strategy:
Management
Policy 5 – AMSA will continue to conserve the lighthouse in accordance with Commonwealth and TAS State heritage listing requirements.
For works requiring heritage approval, AMSA will obtain permission from any relevant state or federal authorities. Continuous and as-needed conservation works will be undertaken as required.
Implementation strategy:
Policy 6 – The cultural significance of the lightstation will be the basis for deciding how to manage it.
The heritage values or cultural significance of the place must be conserved. This heritage management plan includes relevant background information to support this policy (see ‘Section 3 History’).
Implementation strategy:
Policy 7 – Monitor, review and report the Commonwealth heritage values of the lightstation every five years or sooner if major changes to the lightstation occur.
The Commonwealth heritage values of the lighthouse are to be monitored and reported on a regular basis. A Heritage Asset Condition Report is updated for Cape Sorell Lighthouse every two years. The report records historical information, condition, and maintenance requirements for fabric within the lighthouse to ensure a gain and/or loss of heritage value is identified.
Implementation strategy:
Policy 8 – Maintain historical, management and maintenance records within AMSA and make available these records.
As part of the proper process for managing change in significant places, the Burra Charter points out the importance of making records before any change, and advocates placing records in a permanent archive and making them available where this is appropriate. AMSA’s collection of records, which include documents pertaining to heritage intervention, management and maintenance, are subject to this process. Heritage Asset Condition Reports are routinely generated for each heritage lighthouse and stored in AMSA’s record-keeping system. AMSA will continue to practice such processes via their records management systems (RMS).
Implementation strategy:
Policy 9 – Develop and provide appropriate training and resources to all relevant AMSA staff, contractors and licensees.
In order to ensure best practice management of AMSA-operated lighthouses, all staff, contractors and licensees are required to have access to the appropriate training and resources in order to provide best practice conservation of the site.
Implementation strategy:
Policy 10 – Use contractors and service providers with appropriate experience.
AMSA is to ensure parties carrying out work have appropriate knowledge and use effective methods to ensure conservation of the lighthouse.
Implementation strategy:
Policy 11 – Seek heritage advice and apply best heritage practice.
AMSA will continue to use in-house heritage expertise, external consultancy, or a combination of both as required in order to successfully apply best heritage practice. Should in-house heritage expertise be limited in responding to a requirement, external heritage expertise will be engaged to address the issue.
Implementation strategy:
Policy 12 – Appropriate protocol in the event of unforeseen discoveries or disturbances of heritage within the AMSA site.
AMSA’s scope of work rarely involves excavation. Should such work need be undertaken, AMSA will implement a suitable discovery plan and seek advice from suitably qualified personnel as required. In the event of any unforeseen discovery or disturbance of heritage-related items on the AMSA site, notification to the appropriate organisation will occur in accordance with the conditions of the discovery plan. This plan will also be updated accordingly.
Note: In most cases, AMSA’s leases are limited to the immediate vicinity of the lighthouse and therefore this scenario is not anticipated as a likely occurrence.
Implementation strategy:
Policy 13 – Make this heritage management plan available to all persons involved in decision-making on the management of the lighthouse and its setting.
The plan will be made available to all personnel intrinsic to management of the lighthouse and its setting, for example AMSA maintenance contractors, TAS PWS as land manager, staff and other relevant parties.
Implementation strategy:
Future developments
Policy 14 – Adaptation of the place using methods or processes that minimise impact on heritage values and significance in accordance with the Burra Charter principles.
It is likely that over time the lighthouse will house new equipment as technology changes and improves. The Burra Charter principles will be used as the basis for decision-making.
Implementation strategy:
Policy 15 – When required, engage with adjacent landowners to maintain an appropriate setting for the lighthouse in its visual and natural context.
Any changes to the surrounding land, or AMSA leased area, requires careful consideration. AMSA will liaise with all adjacent landowners in the event of any proposed changes that may affect the setting and attempt to influence a positive outcome.
Implementation strategy:
Policy 16 – In the event of adaptive re-use or divestment (instance(s) which would no longer place the lighthouse under AMSA control), AMSA will strive to ensure the Commonwealth and TAS State heritage values of the site are recognised and preserved.
In the event Cape Sorell Lighthouse is no longer identified as a working AtoN, AMSA will withdraw its standing as lessee and hand over all authority to the lessor. This process must be conducted in line with section 341ZE of the EPBC Act.
Implementation strategy:
Community Involvement
Policy 17 – Consult with Traditional Custodians and the wider community in the preparation of the management plan.
AMSA will give Traditional Custodians and the general public an opportunity to review and comment on this management plan through a public consultation process.
Implementation strategy:
Review
Policy 18 – Review this plan within five years of its adoption or sooner if major changes are needed.
This plan will be reviewed every five years. This review should:

Appendix 1. Glossary of heritage conservation terms
The Burra Charter, from its first version (1979) and its current version (2013), defined a set of terms that have since been widely adopted in Australian heritage conservation practice.
Where the following terms are used in this heritage management plan, the particular meanings defined in the charter are intended. The definitions are quoted from Article 1 of the Burra Charter.
Adaptation means modifying a place to suit the existing use or a proposed use.
Associations means the special connections that exist between people and a place.
Compatible use means a use which respects the cultural significance of a place. Such a use involves no, or minimal, impact on cultural significance.
Conservation means all the processes of looking after a place to retain its cultural significance.
Cultural significance means aesthetic, historic, scientific, social or spiritual value for past, present or future generations. Cultural significance is embodied in the place itself, its fabric, setting, use, associations, meanings, records, related places and related objects. Places may have a range of values for different individuals or groups.
Fabric means all the physical material of the place including components, fixtures, contents, and objects.
Interpretation means all the ways of presenting the cultural significance of a place.
Maintenance means the continuous protective care of a place and its setting. Maintenance is to be distinguished from repair which involves restoration or reconstruction.
Meanings denote what a place signifies, indicates, evokes or expresses to.
Place means a geographically defined area. It may include elements, objects, spaces and view. Place may have tangible and intangible dimensions.
Preservation means maintaining a place in its existing state and retarding deterioration.
Reconstruction means returning a place to a known earlier state and is distinguished from restoration by the introduction of new material.
Related object means an object that contributes to the cultural significance of a place but is not at the place.
Related place means a place that contributes to the cultural significance of another place.
Restoration means returning a place to a known earlier state by removing accretions or by reassembling existing elements without the introduction of new material.
Setting means the immediate and extended environment of a place that is part of or contributes to its cultural significance and distinctive character.
Use means the functions of a place, including the activities and traditional and customary practices that may occur at the place.
Appendix 2. Glossary of historic lighthouse terms relevant to Cape Sorell Lighthouse
A
Apron paving – The concrete paving surround the base of the lighthouse tower.
Astragal – the bars which support the glazing of a lantern. They may also support the roof. Simply a framing member between the glazing bars in the lantern glazing. In its true meaning an astragal is a moulding that has a rounded profile. In lanterns this is almost never the case.
B
Balcony – a walk way around the outside of the lantern, used for maintenance and (formerly, when lighthouses were manned) for observing ships. Principal parts are the balcony floor and the balcony balustrade. (Synonym: gallery deck).
Balcony floor – floor of the balcony. Cape Sorell’s balcony floor is a 1899 Chance Bros. cast iron plate.
Balcony balustrade – a handrail together with its supports. The supports are called balusters. Simply a railing or wall on the outer perimeter of the balcony, to prevent people from falling off the balcony. Generally made of metal stanchions and rails. Cape Sorell’s balcony balustrades are of cast iron.
Balcony door – door in the lantern base to give access to the balcony. In AMSA lanterns two doors are sometimes fitted but only one is operational. (Synonym: parapet hatch, service room door).
C
Cast iron – a mixture of iron and carbon with a relatively high carbon content and a low melting point, produced directly from a blast furnace.
Chance Bros – English manufacturer of optical apparatus, lanterns, cast iron stairs, cast iron towers, and other lighthouse components. The Chance family established a glass-making business in Smethwick, England in 1824 and is often described as ‘near Birmingham’. The business was absorbed into the Pilkington group of companies in 1951 and now ceases to exist.
Character – pattern of flashes of light emitted by a lighthouse, designed to identify that particular lighthouse.
Copper – a red malleable metal of low resistivity.
E
External catwalk – a landing around the external face of the tower complete with hand rail. Cape Sorell’s external catwalk is 1899 Chance Bros cast iron lattice panels.
F
Flagstaff – a structure whereby signalling flags could be attached for communication with passing vessels.
I
Intermediate floors – levels found mid-way up a building. Cape Sorell has four slate intermediate floors.
Internal catwalk – an open landing inside the tower complete with handrail. Cape Sorell’s internal catwalk is 1899 Chance Bros cast iron lattice panels.
Iron – there were two common types of iron used in lighthouse construction: wrought and cast. Older lights will almost certainly contain these iron types. Wrought iron has been worked by hand and is an iron alloy with a very low carbon content in contrast to steel, it also has fibrous inclusions. Cast iron is iron which has been heated until it liquefies, and is then poured into a mould to solidify.
L
Lantern – the glazed enclosure, usually of cylindrical or polygonal shape, at the top of a lighthouse, which surrounds and protects the optical apparatus. It contains the optical apparatus, made up of the lantern roof, lantern glazing and lantern base sections.
Lantern floor – the level in a lighthouse at which the lantern is installed, and by which access may be gained to the optical system and to the inside and outside of the lantern glazing. The lantern floor is generally at or near the same level as the catwalk and can be made from steel, concrete, or timber.
Lantern glazing – the middle section of the lantern, circular or polygonal in plan, between the lantern roof above and the lantern base below, made up of glass panes held in a framework of glazing bars. On the landward side there may be blank panels in place of glass, or other opaque construction. Types of lantern glazing include: flat and curved trapezoidal panes and curved diamond/triangular panes. Cape Sorell’s lantern glazings are curved, rectangular glass.
Lantern roof – the roof of the lantern. Usually made of copper sheeting over a framework of rafters.
Lens assembly – a transparent optically refracting element of glass. The surface is usually spherical in form.
Light source – electric bulbs now illuminate most lighthouses.
Lighthouse – the principal structure of a lightstation, generally made up of a lantern, balcony and tower.
Lightstation – a precinct containing a lighthouse structure and other related buildings, for example, keepers’ cottages, store room and signal house.
O
Order – a shorthand expression of the size of an optical apparatus or lantern. At the time the system of orders was established, when kerosene burners were used, longer range lights needed larger burners, and larger burners needed lens assemblies of longer focal length to ensure a sharply defined beam. Thus in turn the lantern rooms were required to be larger to house these lens assemblies. AMSA historic lantern rooms range from 1st to 4th order.
P
Pedestal – part of the optical apparatus, consisting of a metal column or base standing on the balcony floor inside the lantern and supporting the lens assembly and light source. Some later Chance documentation (such as their tariffs 1908) also refer to the lantern base as a pedestal.
T
Tower – structure to support the lantern at a sufficient height above the ground. The most common types are the masonry tower, timber-framed tower, cast iron tower and lattice tower.
