Western Australia is divided into 59 electoral districts in six electoral regions.
At a State election, one member of the Legislative Assembly is elected for each district and six members of the Legislative Council are elected for each region by the electors who live in those districts and regions.
The boundaries of each electorate are determined every four years, 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 at election time.
