Candidate roster boundary
Names stop where the live source stops.
The official site no longer makes the complete 2025 candidate CSV available online. Election.org therefore publishes every official first- and second-vote choice but names only elected people supported by the separate elected-candidates file.
These are official final results for the 23 February 2025 federal election. First votes and second votes are separate. A first-vote plurality did not always produce a constituency seat under the 2025 second-vote-coverage rule.
