Local government representation reviews

A representation review is a process to determine whether a council would benefit from an alteration to its current composition or ward structure to meet future requirements.

A council is required to conduct a review of its representation at least once in each relevant period as prescribed by the regulations of the Local Government Act 1999 (The Act). The Minister for Local Government from time to time will publish a timing schedule for determination of the relevant period.

However, councils may undertake a review at any time into aspects of its composition or ward structure or they may be requested to undertake a review within a specified period by the Electoral Commissioner.

The Act prescribes the process and requirements of the representation review that focuses on all aspects of the composition of the council including:

the number of council members,
the division or abolishment of wards in the council area, and
the number of voters represented by each elected council member.

All reviews must take the principles specified in the Act into account so that:

any changes made are to benefit ratepayers,
arrangements should reflect communities of interest and should avoid separations of such communities,
voters should be afforded effective participation in decisions on local matters, and
Council is able to cooperate with other councils and govern effectively.

Reform to the Act has changed the representation review process. Refer to the following instruments for up-to-date information on council responsibilities and the Electoral Commissioner’s role:

Local Government Act 1999
Local Government (General) Regulations 2013
Local Government (Transitional Provisions) Regulations 2021
Statutes Amendment (Local Government Review) Act 2021

Guideline for councils

The below Representation Review Guideline provides general information for councils conducting a representation review. This should be read in conjunction with the requirements under the relevant legislative instruments.

Review schedule

The schedule for reviews is determined by the Minister of Local Government.

For more information on the representation review process in your area please contact your council.

Background

In South Australia there is one Legislative Council district (the entire state) and forty-seven House of Assembly districts. The number of electors in each House of Assembly electoral district grows at different rates due to differences in population and housing growth.

This means that boundaries need to be reviewed or redistributed from time to time so all districts have a similar number of electors;→

Responsibility

The Electoral Districts Boundaries Commission (EDBC) is appointed under the Constitution Act 1934 to consider the boundaries after every State election.

The Electoral Commission of South Australia (ECSA) is then responsible for implementing the boundary changes. These changes include:

adjusting the electoral roll to reflect the new boundaries
updating records
preparing maps and materials.

ECSA writes to all electors before each State election to advise them of the election and the electoral district they are enrolled in.

Report

On 12 December 2024 the EDBC released its Report on the redistribution of South Australia’s 47 House of Assembly electoral districts.

The new boundaries will take effect at the next State election, on 21 March 2026.

To access a copy of the Report, visit the EDBC website;→

The Local Government Association is your portal for information on councils around the state.

There are 68 councils in South Australia, and all councils participate in local government elections except for the Municipal Council of Roxby Downs.
