Electoral Distribution

Western Australia’s electoral boundaries are reviewed every four year, two years after a State election. This is done to ensure that, as the number and locations of people change over time, all electorates will contain an acceptable range of electors. 

The process for reviewing electorates is prescribed in Part llA of the Electoral Act 1907.

Current distribution

The 2023 review of electoral boundaries will be used at the next State election on 8 March 2025.

Any by-election that occurs prior to 2025 will be conducted in accordance with the current boundaries from the 2019 Distribution.
