Where this comes from
- Results, margins and turnout are the AEC’s published 2025figures. The margin is derived — the winner’s two-candidate-preferred share minus 50 — and the seat status is the AEC’s own classification.
- Suburbs and postcodes come from 2021 Census mesh blocks matched to CED_2025 boundaries, weighted by resident population rather than by area — otherwise a large, largely uninhabited postcode is assigned to whichever division holds the most empty land.
- These are an approximation of the AEC’s legal boundaries, so close to a boundary they can differ. To confirm where you are enrolled, check the AEC.
