1982 Mitcham state by-election
The by-election was triggered by the resignation of former state Democrats MHA Robin Millhouse. The Liberal Party was expected to win the seat, but Democrats candidate Heather Southcott was heavily favoured by Labor party preferences, and was a surprise winner.
The Liberals won the seat six months later at the 1982 state election.
The Australia Party, who contested the previous election and gained 0.3 percent, did not contest the by-election. The Democrats retained the seat by 45 votes.
