State boundary reviews

We provide support to the Electoral Boundaries Commission (EBC). The EBC set the State district and region boundaries.

They also regularly review these boundaries. This is known as a redivision.

A redivision is a consultative process that invites submissions from all members of the public, political parties and any interested groups.

The last State electoral boundary redivision wrapped up in October 2021, and some electoral boundaries have changed as a result of the redivision process.

All changes will come into effect on Tuesday 1 November, when the writ for the 2022 State election is issued.

What's going to change?

Some districts and regions will:

  • change name
  • change boundaries
  • be removed
  • be newly created.

These changes will affect about 20% of enrolled voters.

Do I need to do anything?

If the district or region you will vote in at the next State election is going to change because of the redivision, we will update your enrolment and you don't need to do anything. 

Please remember that if you move address or change your name, it is still your responsibility to keep your enrolment up to date.

When is the next redivision?

Electoral boundary redivisions can be triggered when:

  • there have been two State elections since the last redivision
  • enrolment in some electorates is substantially different to the average number of voters in an electorate for a sustained period
  • there is a change to the number of districts or regions.

When the next electoral boundary redivision is called, we will provide more information.
