Geography
Inner southern Melbourne. Prahran covers the suburbs of Prahran, South Yarra and Windsor and parts of St Kilda and St Kilda East.
History
Prahran has been a state electorate since 1889. It has alternated between the ALP and conservative parties, before falling to the Greens in 2014.
The ALP first won the seat in 1894, holding it until 1900. Liberal MP Donald Mackinnon held the seat from 1900 to 1920. The ALP and conservative parties alternated in control until the 1930s, with the Liberal Party holding the seat until 1945.
In 1945, the ALP’s William Quirk won the seat, holding it until his death in November 1948. The ensuing by-election in 1949 was won by Frank Crean, who had previously held the seat of Albert Park. He left the seat in 1951 when he moved to the federal seat of Melbourne Ports. He served as a federal MP until 1977, playing a senior role in the Whitlam Labor government.
The 1951 Prahran by-election was won by the ALP’s Robert Pettiona, who held the seat until his defeat in 1955.
Since 1955, Prahran has been won by the ALP only four times. In 1955, the seat was won by Sam Loxton, a Liberal candidate. Loxton was a former test cricketer who had been part of Don Bradman’s Invincibles team and played VFL football for St Kilda.
Loxton held the seat until 1979, when the ALP’s Bob Miller won the seat. He held the seat for two terms, and in 1985 unsuccessfully contested the Legislative Council province of Monash.
The Liberal Party’s Don Hayward won the seat in 1985. He had previously held the upper house seat of Monash from 1979 to 1985. He served as Member for Prahran until the 1996 election.
In 1996, the Liberal Party’s Leonie Burke won Prahran. Burke was defeated in 2002 by the ALP’s Tony Lupton. Lupton was re-elected in 2006.
In 2010, Lupton was defeated by Liberal candidate Clem Newton-Brown.
Prahran produced an unusual result in 2014, with the third-placed Greens candidate Sam Hibbins overtaking both Labor and Liberal candidates to win narrowly.
Hibbins was re-elected in 2018, again coming third on primary votes and then overtaking Labor and Liberal to win.
Hibbins gained a sizeable primary vote swing in 2022, with Labor reduced to a clear third place, and he also increased his majority after preferences.
Hibbins resigned from the Greens in November 2024 due to the revelation of a previous affair with a staff member.
Assessment
Prahran has effectively two different axes on which competition takes place – between Labor and Greens to be the leading progressive party, and between those parties and the Liberal Party on the two-candidate-preferred count. The race was close on both axes in 2014. In 2018 the Liberal Party wasn’t competitive but Labor and Greens were still close. In 2022, Hibbins won easily on both.
This seat could be competitive on either axis in Hibbins’ absence, particularly considering the circumstances of his departure.

There’s two possible scenarios.
1. Labor abstains as they didn’t make the final two last time. This would be interesting as it would send Labor voters in different directions and might make it easier for the Liberals to win.
2. The three main parties will run. The Greens vote will drop because Sam Hibbins’s personal vote is now gone and also because of the Greens’ stance on the Israel issue. The southern part has a large Jewish population. I also believe when MPs leave due to poor behaviour or legal issues, their parties would likely cop swings at the following by-election.
I wouldn’t be surprised if Michelle Ananda-Rajah runs here. This is perhaps more winnable than Labor’s third senate spot. Since Higgins will be abolished anyway, there wouldn’t be a point in having a federal by-election.
Whilst this was a former Liberal seat (and a fairly safe one at that) the demographic of this electorate suggests this is a Greens/Labor contest depending on whoever gets ahead in 3CP. Labor could theoretically have a chance with the Greens on the nose due to various reasons but they’re in no strong position themselves in the state as their lifespan is starting to fade. But the Liberals on a state level is also toxic in an electorate like this which is probably the most left wing seat south of the Yarra.
Ananda-Rajah could run but it’s a long shot for her to win because of the reasons above. I predict it’s a marginal Greens retain simply because they appear to be the least worst option for this electorate (as for who’s the worst, I’d have to say the Liberals).
