preface

The AUASB issues Auditing Standard ASA 101 Preamble to AUASB Standards (January 2025) pursuant to the requirements of the legislative provisions and the Strategic Direction explained below.

The AUASB is a non-corporate Commonwealth entity of the Australian Government established under section 227A of the Australian Securities and Investments Commission Act 2001, as amended (ASIC Act).  Under section 336 of the Corporations Act 2001, the AUASB may make Auditing Standards for the purposes of the corporations legislation.  These Auditing Standards are legislative instruments under the Legislation Act 2003.

Under the Strategic Direction given to the AUASB by the Financial Reporting Council, the AUASB is required, inter alia, to develop auditing standards that have a clear public interest focus and are of the highest quality.

This Auditing Standard sets out how AUASB Standards are to be understood, interpreted and applied.  AUASB Standards are to be read and applied in conjunction with this Auditing Standard.

This Auditing Standard replaces existing ASA 101 Preamble to Australian Auditing Standards issued by the AUASB in September 2021 (as amended to November 2021). 

The revised Auditing Standard:

  1.                 expands the scope of ASA 101 to include Australian Standards on Sustainability Assurance ASSA 5000 General Requirements for Sustainability Assurance Engagements and ASSA 5010 Timeline for Audits and Reviews of Information in Sustainability Reports under the Corporations Act 2001; and
  2.                 clarifies that Australian Standards on Quality Management are not legally enforceable under the Corporations Act 2001.


Auditing Standard ASA 101 Preamble to AUASB Standards (January 2025) is set out in paragraphs 1 to A55.

The Auditing and Assurance Standards Board (AUASB) makes this Auditing Standard pursuant to section 227B of the Australian Securities and Investments Commission Act 2001 and section 336 of the Corporations Act 2001.

Dated: 28 January 2025  D Niven
 Chair - AUASB

 

This Auditing Standard has been made for Australian legislative purposes and accordingly there is no equivalent International Standard on Auditing issued by the International Auditing and Assurance Standards Board (IAASB).

Where relevant, the AUASB has aligned the wording of this Auditing Standard with the IAASB’s Preface to the International Quality Management, Auditing, Review, Other Assurance, and Related Services Pronouncements.

* * *

  1.                 Australian Standards on Quality Management (ASQMs)

ASQMs[10] apply to firms in respect of all engagements to which AUASB Standards apply.

The authority of ASQMs is set out in the introduction to each ASQM.

  1.                 Australian Auditing Standards (ASAs)

ASAs, whilst developed in the context of financial report audits, are to be applied also, as appropriate, to audits of other historical financial information.

The authority of the suite of ASAs is set out in ASA 200[11].  ASA 200 deals with the auditor’s overall responsibilities when conducting an audit of a financial report in accordance with ASAs.  Specifically, it sets out the overall objectives of the auditor, and explains the nature and scope of an audit designed to enable the auditor to meet those objectives.  It also explains the scope, authority and structure of the ASAs, and includes requirements establishing the general responsibilities of the auditor applicable in all audits, including the obligation to comply with the ASAs. 

The ASAs, taken together, provide the standards for the auditor’s work in fulfilling the overall objectives of the auditor. The ASAs deal with the general responsibilities of the auditor, as well as the auditor’s further considerations relevant to the application of those responsibilities to specific topics.

  1.                 Standards on Review Engagements (ASREs)

ASREs[12] are to be applied to the review of a financial report and the review of other historical financial information.

  1.                 Standards on Sustainability Assurance (ASSAs)

ASSAs are to be applied to assurance engagements dealing with sustainability information.

ASSA 5000 includes requirements regarding the conduct of a sustainability assurance engagement. ASSA 5010 specifies the information in a sustainability report under the Act that is required to be audited and/or reviewed in accordance with ASSA 5000 for each relevant year.

  1.                 Standards on Assurance Engagements (ASAEs)

ASAEs are to be applied to assurance engagements dealing with subject matters other than historical financial information.[14]

ASAE 3000[15] explains the scope, authority and structure of the ASAEs, and includes requirements regarding the conduct of an assurance engagement in accordance with ASAEs.[16]

Where a subject-matter specific ASAE is relevant to the subject matter of a particular engagement, that ASAE applies in addition to ASAE 3000. The introduction to each subject-matter specific ASAE sets out the relationship of the ASAE with ASAE 3000.

  1.                  Standards on Related Services (ASRSs)

ASRSs are to be applied when an assurance practitioner is engaged to undertake engagements other than assurance engagements covered by ASAs, ASREs or ASAEs.[17]

  1.                 the title page of the standard indicates that it is a compiled version of the standard and shows the date of the compilation and the relevant Amending Standards that have been taken into account;
  2.                 a “Compilation Details” section is included in the standard which includes the following information:
  1.                  a “Table of Standards”, which sets out details of both the principal standard and subsequent Amending Standards, including the dates of both the principal and Amending Standards (date made, operative date and date registered on the Federal Register of Legislation);
  2.                a “Table of Amendments”, which provides details of amendments to the principal standard (paragraph of standard affected, how affected and a paragraph reference to the relevant Amending Standard); and
  3.              a statement that the compilation is not a separate Auditing Standard made by the AUASB but a representation of the relevant Standard which incorporates the original standard and subsequent amendments.
  1.                 the Operative Date paragraph in the standard includes a reference to the Compilations Details section of the standard, for details about the operative dates of paragraphs changed or added by an Amending Standard. (Ref: Para. A33(a))

“Compliance with this Standard enables compliance with the equivalent international standard”.

  1.                 The requirements of each AUASB Standard are contained in a separate “Requirements” section of a standard. The requirements of an AUASB Standard are expressed using the word “shall” to denote the obligations an assurance practitioner is required to comply with in achieving the objective or objectives stated in the standard.
  2.                 Paragraphs containing application and other explanatory material are designated with the letter “A”.
  3.                 The present tense of verbs is used in explanatory material when it is the best form of expression. Use of the present tense does not create or imply requirements. The present tense is used in examples and other explanatory material that relate to professional judgement and professional scepticism.
  4.                 Requirements that exist in another AUASB Standard are anchored back to the original requirement (for example, using the phrase “in accordance with”) when repetition or a cross reference is considered necessary for understanding and context.
  5.                 Australian additions or modifications to an equivalent IAASB Standard are marked as Australian paragraphs or additional appendices commencing with an “Aus” prefix.
  6.                  Deletions from an equivalent IAASB Standard are clearly noted as “Deleted by the AUASB. Refer Aus …”. 
  7.                 The extent of differences between an AUASB Standard and its equivalent international standard are detailed in the “Conformity with International Standards” section of the standard.

The word “including”, as used in AUASB Standards, means a list of items or examples is provided but the list does not purport to contain all relevant items or examples and intentionally is not exhaustive.


[1]  Or ASQC 1, as applicable.  Auditing Standard ASQM 1 Quality Management for Firms that Perform Audits or Reviews of Financial Reports and Other Financial Information, or Other Assurance or Related Services Engagements, issued in March 2021, replaces Auditing Standard ASQC 1 Quality Control for Firms that Perform Audits and Reviews of Financial Reports and Other Financial Information, Other Assurance Engagements and Related Services Engagements from 15 December 2022.

[2]  Pursuant to section 227B(1)(a) of the ASIC Act.

[3]  Pursuant to section 227B(1)(b) of the ASIC Act.

[4]  For legislative purposes, ASQM 1 and ASQM 2 Engagement Quality Reviews are included in legislation as “Auditing Standards” – see paragraph 10(d) of this Preamble.

[5]  “Australian Auditing Standards” is defined in paragraph 10(c) of this Preamble.

[6]  For legislative purposes, ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity and ASRE 2415 Review of a Financial Report: Company Limited by Guarantee or an Entity Reporting under the ACNC Act or Other Applicable Legislation or Regulation, are included in legislation as “Auditing Standards” – see paragraph 10(d) of this Preamble.

[7]  The term “assurance practitioner” is defined in paragraph 10(a) of this Preamble.

[8]  Firm means a sole practitioner, partnership, corporation or other entity of assurance practitioners, or public sector equivalent. The definition of “firm” in relevant ethical requirements may differ from the definition set out in this Auditing Standard.

[9]  Related services engagements include engagements to perform agreed-upon procedures.  The term ‘assurance practitioner’ is referred to in ASRS 4400 Agreed-Upon Procedures Engagements as ‘practitioner’.

[10]  For legislative purposes, ASQM 1 and ASQM 2 are included in legislation as “Auditing Standards”.

[11]  See ASA 200 Overall Objectives of the Independent Auditor and the Conduct of an Audit in Accordance with Australian Auditing Standards.

[12]  For legislative purposes, ASRE 2410 and ASRE 2415 are included in legislation as “Auditing Standards”.

[13]  For example, see ASRE 2400 Review of a financial Report Performed by an Assurance Practitioner Who is Not the Auditor of the Entity, paragraphs 9-12.

[14]  Examples of such subject matters include the efficiency and/or effectiveness of an entity’s activities, prospective financial information and the effectiveness of internal controls. The AUASB’s Framework for Assurance Engagements, which defines and describes the elements and objectives of an assurance engagement, provides the context for understanding ASAEs.

[15]  See ASAE 3000 Assurance Engagements Other than Audits or Reviews of Historical Financial Information.

[16]  See ASAE 3000, “Introduction” (paragraphs 1-8) and “Conduct of an Assurance Engagement in Accordance with ASAEs” (paragraphs 14-20).

[17]  Examples of financial and non-financial subject matters on which Standards on Related Services may be applied include: Agreeing the eligibility of expenditures claimed from a funding program; Recalculating revenues for determining royalties, rent or franchise fees based on a percentage of revenues; Confirming the calculation of capital adequacy ratios for regulatory authorities; Observation of the destruction of fake or defective goods reported to a regulatory authority; and Tracing data generating processes for lottery draws reported to a regulatory authority.

[18]  For example, see ASRS 4400, paragraphs 7-10. Where this information is not included in the introduction of an ASRS, for example ASRS 4450 Comfort Letter Engagements, relevant terms are to be interpreted in a directly analogous way to how they are explained in the context of ASRS 4400.

[19]  For legislative purposes, ASRE 2410 and ASRE 2415 are included in legislation as “Auditing Standards”.

[20]  Reference to a ‘financial report’ includes not only a financial report as defined under Part 2M.3 of the Act, but also a financial report prepared for other purposes. Financial reports required by Part 2M.3 of the Corporations Act are:

[21]  These standards are classified as disallowable legislative instruments under the Legislation Act 2003.  The AUASB has adopted certain drafting principles in making Auditing Standards under the Australian regulatory environment, wherein the Auditing Standards are legally enforceable and registered as legislative instruments under the Legislation Act 2003.

[22]  Section 307A of the Corporations Act requires auditors to conduct audits and reviews of financial reports prepared under Part 2M.3 of the Act in accordance with Auditing Standards.

[23]  See APES 210 Conformity with Auditing and Assurance Standards, issued by the APESB.

[24]  In Australia the term “government audit agencies” refers to State, Territory or Commonwealth Auditors-General.

[25]  The term “professional judgement” is defined in the AUASB Glossary in the context of different types of AUASB Standards.  For assurance engagements, see Framework for Assurance Engagements, paragraphs 56-60.  For related services engagements, see ASRS 4400, paragraphs 13(j) and 18.

[26]  For further details, refer to Framework for Assurance Engagements, paragraphs 5-9.

[27]  See ASA 102 Compliance with Ethical Requirements when Performing Audits, Reviews and Other Assurance Engagements. 

[28]  For example, see ASA 220 Quality Management for an Audit of Financial Statements.

[29]  For example, a standard might have a principal version issued in 2015 amended by Amending Standards (legislative instruments) that become effective, one each year, from 2016. Therefore, in 2020 the compiled version of the standard will reflect the amendments effective from 2016 through to 2020.
