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.
Relevant dates for the 2019 review are set out in the 2019 Distribution timetable.
These boundaries remain in effect but will be reviewed in time for the 2021 State election.
Previous State electoral boundaries
