PROPOSED Redistribution of Federal Electoral DIVISIONS IN South Australia:
27 March 2026

The Redistribution Committee for South Australia (the Redistribution Committee) has made a proposed redistribution of federal electorates in South Australia.

Members of the public and organisations are invited to inspect:

• the Redistribution Committee’s proposed report showing reasons for the redistribution,
• maps showing the names and boundaries of each proposed electorate, and
• suggestions and comments on suggestions previously lodged with the Redistribution Committee.

The Redistribution Committee’s report and maps of the proposed redistribution are available on the AEC website (www.aec.gov.au/sa-redistribution).

From Friday 27 March 2026, objections (ideas on the proposed redistribution) and comments on objections (feedback on ideas) to the proposed redistribution can be received.

WHY IS A REDISTRIBUTION BEING CONDUCTED?

On 12 August 2025, in accordance with section 59 of the Electoral Act, the Electoral Commission directed that a redistribution commence because more than seven years had elapsed since the last redistribution.

LEGAL REQUIREMENTS FOR A REDISTRIBUTION

In making its proposed redistribution, the Redistribution Committee was 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 was determined by the Electoral Commissioner to be 130,786 as at 12 August 2025.

As far as practicable, the Redistribution Committee must ensure that the number of electors enrolled in each electorate at 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 electors.

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;

1.                  means of communication and travel within the proposed Electoral Division;

(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 PROPOSED FEDERAL ELECTORATES

The Redistribution Committee has proposed changing the boundaries of 7 of South Australia’s 10 federal electorates. The electorates of Adelaide, Hindmarsh and Sturt are proposed to have no changes.

As a result of the proposed redistribution, 51,659 electors enrolled in South Australia (or 3.95 per cent of all electors enrolled in South Australia on 12 August 2025) will change their federal electorate.

The Redistribution Committee has proposed renaming the current electorate of Grey to the electorate of O’Donoghue. This is to honour the legacy of Dr Lowitja O’Donoghue AC CBE DSG (1932–2024) for her lifelong work in health, advocacy and public administration, especially for Indigenous people. The Committee proposes retaining the names of the other nine electorates in South Australia.

The proposed renaming of an electorate will affect 133,313 electors (or 10.19 per cent of all electors enrolled in South Australia on 12 August 2025) as a result of the proposed redistribution.
