The Division of Corangamite is an Australian electoral division in the state of Victoria. The division was proclaimed in 1900, and was one of the original 65 divisions to be contested at the first federal election. It is named for Lake Corangamite, although the lake no longer falls within the division's boundaries. The division was redrawn in 2021, becoming a much smaller seat due to increased population growth. It now covers (down from ) along the Victorian coast, including the growing surf coast area, the southern suburbs of Geelong as well as rural areas to the west. Starting at in the east, the electorate takes in the entire Bellarine Peninsula, then runs down the surf coast as far as . The electorate then extends north into the Golden Plains Shire, where it includes the towns of , and . Since the 2019 federal election, the current Member for Corangamite is Libby Coker, a member of the Australian Labor Party. Geography Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned. History Until the 1930s it was usually a marginal seat which leaned toward the conservative parties, but was won by the Australian Labor Party during high-tide elections. In 1918, it was the first seat won by what would become the Country Party. It was held by the Liberals (and their immediate predecessor, the United Australia Party) without interruption from 1934 to 2007. A reasonably safe seat for most of the time from the 1950s to the 1990s, it became increasingly less safe from 1998 onward as successive redistributions pushed it further into Geelong. This resulted in the seat falling to Darren Cheeseman, the Labor candidate, by less than one percent at the 2007 federal election for the first time since 1929. Cheeseman was only the third Labor member ever to win the seat. Labor retained the seat in 2010 election against former journalist Sarah Henderson, making Cheeseman the first Labor MP to win re-election in the seat. Henderson sought a rematch in 2013, and won. Henderson retained her seat in 2016 but a redistribution completed prior to the 2019 election pushed the seat further
