2022 Polling Place Results

The Liberal Party polls most strongly in the southern and beachfront suburbs including Henley Beach, West Beach and Fulham, while Labor's strongest parts of Colton are in and around Grange and Kidman Park.

Background

The electorate is named after Mary Colton (1822-98), who arrived in Adelaide in 1839 and worked for the welfare of women and children. Colton was president of the Women's Suffrage League and lived long enough to see the introduction of equal voting rights for women in 1894, a world first for South Australia.

The name Colton was adopted in 1993 for an electorate previously known as Henley Beach. Henley Beach had been held by the Liberal Party's Bob Randall during the one term of the Tonkin government, but was won by Labor through the 1980s despite several attempts by Randall to regain the seat.

At the 1993 election, the Liberal Party opted for the high profile of former Adelaide Lord Mayor Steve Condous, who was easily elected in the landslide and retained the seat despite a state-wide swing back to Labor in 1997. Condous retired at the 2002 election when Labor's Paul Caica won the seat. Significantly, Labor's two gains from the Liberal Party at the 2002 election, Adelaide and Colton, were both contests where the sitting Liberal MP retired.

Caica was easily re-elected with a 12.7 per cent swing in his favour in 2006, cancelled out by a 12 per cent swing back to the Liberal Party in 2010, returning Colton to its more normal marginal status. Caica retained the seat but lost another 2.2 per cent from his margin in 2014.

Colton was one of the seats transformed into a notional Liberal seat by the 2016 redistribution. Caica did not contest the 2018 election when the seat's notional Liberal majority was confirmed by victory for the Liberal Party's Matt Cowdrey. Cowdrey had a 4 per cent swing in his favour on election, the fourth largest swing to the Liberal Party at the election. He lost 1.4 per cent from his margin in 2022, but with only three candidates running in the seat, still managed to win a majority of the first preference vote. He announced his retirement from parliament in June 2025, declaring a desire to "move on from partisan politics".
