Australian federal election, 2025
Division of Corangamite, Victoria

Named for: Lake Corangamite (Indigenous word meaning "bitter water"), which was in the Division until 2019. (It is not known who named Lake Corangamite: presumably early landholders. The name was in use in its present form by 1842. In 2018 and again in 2021 the Electoral Commission proposed renaming Corangamite, on the grounds that Lake Corangamite is no longer in the Division. But both times local opposition to renaming the Division prevailed.)

    Division of Corangamite

    Corangamite has existed since Federation, and for most of its history was located in south-west Victoria, based on Colac and the surrounding rural areas. Until 2018 its boundaries had changed very little over the years, but its demographics did change. The outer suburbs of Geelong spread into the north-east of the seat, and the population of the Surf Coast towns increased greatly. This made what was once a very safe Liberal seat increasingly marginal. Although the seat has a fairly high income level for a regional seat, it has the usual low proportion of people born in non English speaking countries. It also has a high level of over-65s, reflecting the growth of retirement towns along the coast.

    The 2018 redistribution changed the seat substantially, removing Colac and most of the rural areas, while adding the fast-growing Bellarine Peninsula communities of Leopold and Portarlington. The 2021 and 2024 redistributions took the process even further, cutting the seat back to the Geelong suburbs and the Bellarine towns, and removing all the Surf Coast towns except Torquay. The seat is now a mix of coastal towns and outer Geelong suburbs, most of it politically marginal. Labor's strongest areas are Geelong suburbs such as Grovedale, and the remaining Surf Coast towns, notably Torquay. The Liberals dominate the remaining rural areas and some outer Geelong suburbs such as Ceres.

    Jim Scullin, later Prime Minister, held Corangamite for one term (1910-13). At a by-election in 1919 Corangamite elected a Victorian Farmers Union candidate, William Gibson, marking the arrival in federal politics of what soon became the Country Party.

    Tony Street, Foreign Minister in the Fraser Government, held the seat from 1966. He resigned in 1984 and was succeeded by Stewart McArthur. McArthur came from an old Western District family (his father Sir Gordon was a state MP for many years), but by 2007, when he was 70, he had been overtaken by the changes in the seat. He was defeated by Labor's Darren Cheeseman, who was narrowly re-elected in 2010. Cheeseman was defeated in the strong swing to the Liberals in Victoria in 2013. He later become state member for South Barwon.

    Sarah Henderson, a barrister and former TV news reporter, won Corangamite in 2013 and was re-elected in 2016 with her majority only slightly reduced. In 2018 she was appointed Assistant Minister for Social Services, Housing and Disability Services. But the 2018 redistribution wiped out her majority, and in 2019 she was defeated - making the seat one of Labor's only two gains in that election. She was later appointed to a Senate vacancy.

    Libby Coker, Labor MP for Corangamite since 2019, is also a former journalist, and was twice Mayor of the Surf Coast Shire. On the new boundaries, Corangamite is a more compact and more urban seat than previously. This should favour Coker's chances of re-election, but this remains a highly marginal seat. The Liberal candidate in 2025 will be Darcy Dunstan, described as a tradesman and business owner.
