Redistribution of Federal Electoral divisions IN South Australia
In accordance with section 64 of the Commonwealth Electoral Act 1918 (Electoral Act), the Electoral Commissioner invites interested individuals or organisations to make written suggestions to the South Australian redistribution. From Wednesday 8 October 2025, suggestions are able to be made about the redistribution of federal electoral divisions in South Australia, and subsequently written comments on the suggestions which are lodged.
A redistribution of federal electoral divisions in South Australia is required because more than seven years have elapsed since the last redistribution. On Tuesday 12 August 2025, in accordance with section 59 of the Electoral Act, the Electoral Commission directed that a redistribution commence.
In making its proposed redistribution, the Redistribution Committee for South Australia is bound by section 66 of the Electoral Act.
The number of electors in each proposed electoral division must not deviate by more than 10 per cent above or below the redistribution quota. The redistribution quota for South Australia is 130,786.
As far as practicable, the Redistribution Committee will ensure that the number of electors enrolled in each electoral division at Monday 8 April 2030 (the projection time) will not deviate by more than 3.5 per cent above or below the projected enrolment quota of 136,333.
Section 66 of the Electoral Act also provides that the Redistribution Committee:
‘give due consideration, in relation to each proposed Electoral Division, to:
(i) community of interests within the proposed Electoral Division, including economic, social and regional interests;
(iv) the physical features and area of the proposed Electoral Division; and
(v) the boundaries of existing Divisions in the State or Territory’
Consideration of existing boundaries is subordinate to the other factors set out above.
THE BOUNDARIES OF THE ELECTORAL DIVISIONS WILL CHANGE
On the boundaries in place when the redistribution commenced on Tuesday 12 August 2025, all South Australian federal electoral divisions met the requirement for their enrolment to be within plus and minus 10 per cent of the redistribution quota of 130,786. However, four federal electoral divisions do not meet the requirement to be within plus and minus 3.5 per cent of the projected enrolment quota of 136,333 at the projection time of Monday 8 April 2030.
As a consequence, the Redistribution Committee will be required to adjust the boundaries of electoral divisions so that the requirements of the Electoral Act can be met. In adjusting the boundaries of the four federal electoral divisions which do not currently meet the required parameters, it may become necessary to adjust the boundaries of other federal electoral divisions. This will ensure they also meet the required parameters.
The Electoral Act requires that submissions to the Redistribution Committee be made publicly available. Copies of all submissions will be made available in full on the AEC website.
Signatures and any identifying residential addresses of people and organisations that lodge written submissions will be removed prior to publication.
Persons or organisations intending to make submissions to the Redistribution Committee are urged to take account of the requirements of the Electoral Act. In particular, those making submissions are advised to ensure their submissions are received by the AEC by the relevant closing time.
It is strongly recommended those wishing to make suggestions or comments on suggestions read the ‘Have your say’ page on the AEC’s website.
