Electoral Boundaries

An electoral boundary is an area of a given size or population that is represented by a seat in the House of Assembly.

The number of electors in each electoral district grows at different rates due to differences in population and housing growth. This means boundaries need to be redistributed or redrawn from time to time so all districts have a similar number of electors. The Electoral Districts Boundaries Commission is appointed under the South Australian Constitution to consider the boundaries after every election.

The Electoral Commission SA is responsible for implementing the boundary changes. These changes include:

  • Adjusting the electoral roll to reflect the new boundaries
  • Updating records
  • Preparing maps and materials.

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

To view maps of the boundaries for the next election see our 2014 State election boundaries page.
