The first successful female candidate for the Legislative Assembly was Edith Cowan, who was elected as the member for West Perth in 1921 representing the Nationalist Party of Australia.
Cowan was defeated in 1924 but in 1925 May Holman was elected to the seat of Forrest in a by-election, becoming the first successful Labor woman in Australia.
Holman was joined by Florence Cardell-Oliver of the Nationalist Party in 1936, who would become the first female cabinet minister.
