State electoral boundaries

 


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.
