History
editThe electoral district is named after Mary Colton, who arrived in Adelaide in 1839 and worked for the welfare of women and children. She was the President of the Women's Suffrage League, and lived to see the introduction of equal voting rights for women in 1895.
Colton was created to replace the abolished seat of Henley Beach in the 1991 electoral redistribution as a notionally marginal Liberal seat. It was first contested at the 1993 election, where it was won in a large swing to the Liberals by former Adelaide City Council Lord Mayor Steve Condous, recording a 60.5 percent two-party vote from a 9.5 percent two-party swing. This was reduced at the 1997 election to 54 percent, and upon Condous' retirement at the 2002 election, it was won by Paul Caica for Labor with a 54.6 percent two-party vote, which increased to 66.3 percent at the 2006 election. This was reduced to 54 percent at the 2010 election and 51.5 percent at the 2014 election.
Caica announced in February 2017 that he would be retiring from parliament as of the 2018 election.[2]
Bellwether electorate
editColton could be considered South Australia's state bellwether seat as it is the only current lower house seat in parliament to have been consistently won by the party to form government.[citation needed] Only Colton and Adelaide changed from Liberal to Labor at the 2002 election when Labor won government from the Liberals, with Adelaide won by the Liberals in 2010. On 2014 election results and a uniform swing, Colton would have been the Liberal's 24th seat to form majority government. The previous, abolished seat of Henley Beach was also won by the government of the day since its creation at the 1970 election. Colton/Henley Beach as the bellwether for decades of elections also concurrently decided the result in the one-seat parliamentary majority outcomes of 1975, 1989, 2002 and 2014.[citation needed]
Despite the long bellwether history, the 2016 redistribution ahead of the 2018 election changed Colton from a 1.5 percent Labor seat to a notional 3.7 percent Liberal seat.[3]
The seat's bellwether streak was broken in the 2022 election, when incumbent Liberal Matt Cowdrey retained the seat despite Labor forming government.
