This enrolment data has been prepared for the information of individuals and organisations interested in the redistribution of federal electorates in Queensland.
Queensland enrolment data
The file contains:
- federal electorate name
- SA2 name
- SA1 and SA2 number
- enrolment as at 28 July 2026
- projected enrolment as at 27 August 2028
- SA1 growth rate.
What enrolment data is supplied?
For the purposes of the redistribution, the AEC has made available:
- enrolment in Queensland as at 28 July 2026, the day on which the redistribution commenced
- projected enrolment in Queensland at 27 August 2028.
Enrolment as at 28 July 2026 (the commencement date) is supplied as these figures were used for the Electoral Commissioner's determination of the redistribution quota under section 65 of the Commonwealth Electoral Act 1918 (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 electorate does not deviate by more than 10 per cent above or below the redistribution quota. The redistribution quota for Queensland was determined by the Electoral Commissioner to be 127,259.
Projected enrolment at 27 August 2028 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 electorate at 27 August 2028 (the projection time) will not deviate by more than 3.5 per cent above or below the projected enrolment quota. The projected enrolment quota for Queensland is 132,526.
A growth (%) figure is also provided. This is the estimated growth rate for the period 28 July 2026 to 27 August 2028. 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 electorate in Queensland:
- the name of each SA2 in the federal electorate
- the identifier number of each SA1 or part SA1 in the federal electorate
- the two sets of enrolment figures and the growth rates applicable to each SA1 and part SA1 and for each existing federal
- total enrolment for the federal electorate.
Why is SA2 level data included?
Statistical Areas Level 2 (SA2) are areas defined in the Australian Statistical Geography Standard (ASGS) and consist of one or more whole Statistical Areas Level 1 (SA1s). Where possible, SA2s consist of whole gazetted suburbs or rural localities. In urban areas, SA2s often represent single suburbs or combinations of whole suburbs, while in rural areas they define functional zones of social and economic links. Geography is also taken into account in SA2 design.
Why is data supplied at the SA1 level?
Enrolment figures are provided at the SA1 level, as this level is the smallest commonly used geographic building block. The SA1 figures can be aggregated to show the totals for SA2s, which are comprised of a number of SA1s.
The figures shown are broken down according to federal electorate. Where a SA1 or SA2 crosses federal electorate boundaries, the SA1 or SA2 concerned will be listed in each federal electorate in which electors are enrolled. Only those voters residing in that federal electorate are included in the figures for such SA1s or SA2s.
How is projected enrolment calculated?
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 a paper provided by the ABS.
Spatial data and maps
Spatial data and the maps of federal electorates in Queensland are available on the AEC maps and spatial data page.
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.
