Changes to council boundaries

Local Government (Boundary Adjustment) Amendment Act 2017

On 22 August 2017, the Local Government (Boundary Adjustment) Amendment Act 2017 was assented to by the Governor.  The Amendment Act commenced on 1 January 2019, and significantly reforms the processes within the Local Government Act 1999 (the Act) that govern changes to council boundaries. Further information is contained within the attached Explanatory Paper (PDF 328 KB).

The procedures for council boundary changes are set out in the Local Government Act 1999 (Chapter 3, Part 2), which can be accessed via the South Australian Legislation website. The Boundaries Commission, the independent body that assesses and investigates boundary change proposals, and makes recommendations to the Minister responsible for the Act, has prepared Guidelines that detail the process by which it will receive, assess and progress council boundary change proposals.

Sometimes there is confusion between council boundaries and boundaries under planning legislation. Details of planning boundaries and policy can be found at

Guidelines for preparing a proposal

Note: Guideline 6 was amended on 11 February 2019 to clarify how groups and body corporates should be considered to determine the prescribed number of eligible electors.
