Yesterday, the Prime Minister of Australia, Anthony Albanese, announced that the next Australian federal election will be held on May 3. The leader of the center-left Labor Party currently holds a very slim majority in Parliament. To achieve a majority government in the next Parliament, a party must win at least 76 seats out of 150 in the House of Representatives. If no party reaches this number, a hung parliament occurs, requiring parties to negotiate to form a minority government.
Following Albanese's announcement, The Guardian was quick off the mark, immediately publishing an Interactive guide to electorates in the 2025 Australian election: from safe to marginal. This interactive map allows voters to select any of the 150 electorates to learn more about the seat, including its recent political history (with a timeline of past election winners) and demographic data from the latest census.
The map itself features two main visualization views. A traditional 'geographical' view displays all 150 electorates on a standard map of Australia. Meanwhile, the 'exaggerated' view uses a gridded cartogram to show all electorates as equal-sized areas, making it easier to compare electorates visually. Additionally, users can switch between two color-coded seat views: a 'winning party' view, which displays electorates based on the current controlling party, and a 'by margin' view, which highlights the competitiveness of each seat.
