Enrolment statistics
Quota
The Electoral Act 1992 requires each of Queensland’s 93 electorates to have a ‘reasonable proportion of electors’ (quota). The quota is calculated by dividing the total state enrolment by the number of electoral districts (93) to determine the average enrolment.
The Electoral Act provides that the number of electors in each electoral district is to be within the range of 10% above or below the quota. Based on May 2025 enrolment, electoral districts must remain within the variation range shown below to remain within quota:
Enrolment | Districts | Average enrolment | Upper threshold | Lower threshold |
|---|---|---|---|---|
3,744,585 | 93 | 40,264 | 44,290 | 36,238 |
Large districts
As a result of Queensland's size and geography, the Electoral Act makes provision for large remote and rural districts that are much larger in size but have fewer electors than their urban counterparts.
Under the Electoral Act, electorates with a geographical area of 100,000km2 or more have an 'additional large district number' added to their enrolment figures. A number equal to 2 per cent of the total area of the district is added to the number of actual electors to determine a weighted enrolment figure.
The total weighted enrolment figure (including the additional large district number) must be within the range of 10% above or below the average district enrolment to remain within quota.
There are currently four electorates in this category: Cook, Gregory, Traeger and Warrego.
An example of this calculation is set out below:
District | Enrolment (May 2025) | District area (km2) | Additional large district number (2%) | Weighted enrolment figure |
|---|---|---|---|---|
Traeger | 27,662 | 428,911 | 428,911 x 0.02 = 8,578 | 27,662 + 8,578 = 36,240 electors |
Enrolment projections
The Commission will also consider projected enrolment estimates provided by the Queensland Government Statistician’s Office to ensure that all 93 districts remain in quota to the greatest extent possible. The June 2032 State-wide projected enrolment and variation range are shown below:
Projected enrolment | Districts | Average projected enrolment | Upper threshold | Lower threshold |
|---|---|---|---|---|
4,155,112 | 93 | 44,679 | 49,147 | 40,211 |
Downloadable information and statistics
The following downloadable files contain May 2025 enrolment data and June 2032 projected enrolment data, for each electoral district and Statistical Area Level 1 geographic area (SA1). SA1 geographic units are used as building blocks to form electoral districts and calculate total district enrolment.
Currently, most SA1s are located entirely within a single electoral district, however in some cases parts of an SA1 occupy parts of two or more districts. It is important to note that in the latter case, the SA1 is represented as a whole record and is not split across districts.
The data provided below is current as at May 2025. Updated enrolment data will be obtained following the second stage of consultation and published for future consultation stages when the proposed redistribution is released.

Projected enrolment figures provided by the Queensland Government Statistician’s Office.
Attribution: Projected electors are derived from Queensland Government Population Projections, 2023 edition, unpublished data, Queensland Government Statistician’s Office, and elector counts as at 30 November 2024.
Geography: SA1 boundaries are based on the Australian Statistical Geography Standard (ASGS) Edition 3, released in 2021.
Caution: The accuracy of projections generally declines for small geographical units. As such, SA1 level results should be used with caution and should be aggregated into larger geographical areas for use where possible.
These projections are informed by the results of the 2023 edition Queensland Government population projections which were prepared using the latest information available at the time of production (2022). Elector projections are modelled using additional inputs and assumptions notably elector counts as at 30 November 2024.
Variation above or below the figures provided is to be expected, because projections rely on the accuracy of the assumptions used, as well as the quality of data on which they are based.
Changes in actual elector counts between different time points can also be a result of other processes beyond demographic changes (births, deaths and migration).
