2025 Prahran state by-election


The 2025 Prahran state by-election was held on 8 February 2025 to elect the member for Prahran in the Victorian Legislative Assembly, following the resignation of incumbent MP Sam Hibbins, who had held the seat for the Victorian Greens since the 2014 election. The poll took place on the same day as a by-election for Werribee.
Hibbins resigned from the Greens on 1 November 2024, after it emerged that he had engaged in an extramarital affair with a staff member from his office, which he described as a "human mistake". He moved to the crossbench and sat as an independent until delivering his resignation as a member of parliament on 23 November 2024.
The by-election was won by [Victorian Victorian Liberal Party|Liberal Party|Liberal] candidate Rachel Westaway with a two-candidate-preferred vote swing of 13.6% against the Greens. Greens leader Ellen Sandell conceded defeat the day after the by-election, blaming the loss on [|preference flows] and the by-election's timing.

Background

Seat details

Prahran is an electoral district in the inner-southern suburbs of Melbourne, encompassing the suburbs of South Yarra, Windsor, parts of St Kilda and St Kilda East. The seat has existed since 1889 and has experienced notable political shifts over the years. In 1951, the seat saw a by-election which was won by the Labor Party. Historically, the electorate has alternated between the Labor and Liberal parties. However, in 2014, the Greens made a significant breakthrough when Sam Hibbins won the seat, despite finishing third in the primary vote, by securing preferences from the two major parties. Before his resignation, Hibbins would go on to retain the seat for the Greens at the time, narrowly in 2018 and increasing the party's margin in 2022.
Demographically, Prahran is one of Victoria's more affluent electorates. At the time of the 2021 Australian census, the seat had a median weekly personal income of $1,330, significantly higher than the state and national averages. More than half of residents hold a bachelor’s degree or higher, and the median age of residents is slightly younger than both the state and national rates.
