version 0.2 (08/10/2025)
This is a free graphical tool designed to assist with the redistribution of Australian electoral divisions.
Australian states and territories are divided into a specified number of electoral divisions, which must be redrawn to be within a given enrolment range during the redistribution process, which is triggered every 1 to 3 elections according to state or federal law.
The ABS divides the country into 2,472 named Statistical Areas Level 2 (SA2s) which are divided into 61,844 Statistical Areas Level 1 (SA1s). These are the building blocks used to create electoral divisions within this tool.
In practice, SA1s are occasionally split between multiple divisions, however for the purposes of this tool SA1s cannot be split and have been fully placed in the most logical single division. As a result, some divisions will have enrolment numbers that slightly differ from the offical figures.
1. Click any of the redistribution scenarios to open the tool in a new tab
2. Click any division in the left panel to select or unselect it
3. Click on any SA1 on the map to transfer it into the selected division
4. Click on any transferred SA1s to return them to their original division
5. Shift-click can be used to transfer or return whole SA2s
The files for the larger states can be up to 50MB as they contain all of the necessary shape and enrolment data. Ensure that your browser has enough free memory before opening.
At this stage, the tool has no save or load functionality so please keep that in mind.
The author of this tool has no political affiliation and has taken effort to ensure that no political bias has been introduced. All calculations are based on SA1 enrolment data provided by the relevant electoral body, however no guarantee is made that aggregate enrolment calculations will be error-free. The tool is offered as-is, and any usage of the tool is made at the user's own risk.
