    Division of Wannon

    Wannon has existed since Federation, and has always occupied part of the Western District in the south-western corner of Victoria, one of Australia's wealthiest agricultural areas, with an economy based on wool-growing. Until the 1950s the area had a large rural working class and also many small farmers, who provided a voting base for Labor, and the seat was frequently marginal. Since the 1960s it has become increasingly conservative. It still has a high proportion of its workforce engaged in agriculture (20.5%, the 4th highest in the country), and the 4th lowest proportion of non English-speaking households of any electorate. There is some Labor vote in Portland, Warrnambool and the Surf Coast towns, but Hamilton and the rural parts of the seat are overwhelmingly Liberal.

    Recent redistributions both extended the seat eastwards, taking in all the rural parts of the seat of Corangamite. Wannon now effectively covers the whole of the Western District, as well as the Surf Coast as far north as Anglesey. This has slightly reduced the Liberal majority.

    Wannon's most eminent member has been Malcolm Fraser, Prime Minister from 1975 to 1983. Fraser won the seat from Labor in 1955 at his second try, and went on to consolidate the seat for the Liberals, greatly helped by the Labor Split of the 1950s and Labor's demographic decline in the area. He was succeeded by David Hawker, who was Speaker of the House from 2004 to 2007. He retired in 2010.

    Dan Tehan, Liberal MP for Wannon since 2010, is the son of Marie Tehan, who was a state minister in the 1990s. He was a public servant, diplomat and ministerial adviser before his election. He was also deputy state director of the Victorian Liberal Party. He has been rapidly promoted and was Minister for Social Services in the Turnbull ministry. He was promoted to Minister for Education and Minister for Trade, Tourism and Investment in the Morrison ministry. At the 2022 election Tehan was run close by an independent candidate, Alex Dyson, a Warrnambool broadcaster and journalist. Dyson is running again in 2025.
