The upcoming 2025 Australian federal election will feature 150 electorates, which is one less than in 2022, following the abolition of two electorates and the establishment of a new electorate, Bullwinkel, in Western Australia.

Recent analyses of seat margins and boundary changes, informed by data from ABC's Antony Green, reveal significant shifts in the electoral landscape since the last election.

Demographic and infrastructure statistics utilized in this analysis are primarily based on the 2021 census and Australian Bureau of Statistics datasets, adjusted for the recent electoral redistributions.

The interactive features of this election coverage, including demographic and electoral analysis, are supported by data from Griffith University’s Relational Insights Data Lab.

An interactive map and seat explorer will be available to illustrate the estimated margins and changes in electorates resulting from boundary redistributions.

The candidate list for the election currently includes announcements from major and prominent minor parties, with updates expected as more candidates confirm their participation.

Notably, Andrew Gee, who won the Calare seat for the Nationals in 2022, will run as an independent in 2025 after leaving the party in 2023.

Similarly, Russell Broadbent, who secured the Monash seat as a Liberal in 2022, is contesting the upcoming election as an independent after departing from the Liberal party in 2023.

The incumbents for the electorates of Bennelong and Menzies have shifted; Labor currently holds Bennelong, while a Liberal MP represents Menzies, reflecting changes in estimated margins due to electorate redistributions.

Insights into the electoral changes since the last election are further supported by the seat margins following redistributions, sourced from Antony Green.
