The enrolment data provided by the Australian Electoral Commission (AEC) have been prepared for the information of persons and organisations interested in the redistribution of federal electoral divisions in WA.
For the purposes of the redistribution, the AEC has made available:
Enrolment as at Wednesday 15 July 2020 is supplied as these figures were used for the Electoral Commissioner's determination of the current enrolment quota under section 65 of Commonwealth Electoral Act 1918 (the Electoral Act). In making a proposed redistribution, the Redistribution Committee and the augmented Electoral Commission are bound by the Electoral Act to ensure that the number of electors in each proposed federal electoral division does not deviate by more than 10 per cent above or below the current enrolment quota. The current enrolment quota for WA was determined by the Electoral Commissioner to be 112,172 as at Wednesday 15 July 2020.
Projected enrolment at Sunday 2 February 2025 is supplied because, as far as practicable, the Redistribution Committee and the augmented Electoral Commission are required to ensure that the number of electors enrolled in each federal electoral division at Sunday 2 February 2025 (the projection time) will not deviate by more than 3.5 per cent above or below the projected enrolment quota.
A growth (%) figure is also provided. This is the estimated growth rate for the period Wednesday 15 July 2020 to Sunday 2 February 2025. The growth rate shown for each SA1 is calculated by subtracting the actual enrolment from the projected enrolment, then dividing by the actual enrolment. The result is expressed as a percentage.
The following information is provided for each federal electoral division in WA:
Following a recommendation by the Joint Standing Committee on Electoral Matters (JSCEM) that the AEC and the Australian Bureau of Statistics (ABS) work together on enrolment projections, the ABS has supplied enrolment projections to the AEC using AEC enrolment data as the base. The ABS has used a cohort-component method to project the enrolment of each SA1. The methodology is detailed in the paper included with the projected enrolment.
Enrolment figures are provided at the SA1 level, as this level is the smallest commonly used geographic building block. The SA1 figures are aggregated to show the totals for SA2s, which are comprised of a number of SA1s. Being somewhat larger than SA1s, SA2s may be more manageable for those who are interested in less detailed analysis.
The figures shown are broken down according to electoral division. Where a SA1 or SA2 crosses divisional boundaries, the SA1 or SA2 concerned will be listed in each electoral division in which electors are enrolled. Only those electors resident in that electoral division are included in the figures for such SA1s or SA2s.
Data is provided in the following files:

The existing federal boundaries for WA are provided in a spatial format.
You will need GIS software to view and manipulate spatial data; however TAB files have been provided for those who do not have GIS software.
Spatial data and the maps of federal electoral divisions in WA are available on the AEC maps and spatial data page.
