Politics
A long-time member of the Liberal Party, she contested and won preselection for the National-held seat of Landsborough upon the 1990 resignation of former Premier Mike Ahern. She won an upset victory after Labor declined to stand a candidate, winning a 15% swing in her favour. In November 1991, she defeated Denver Beanland for the Liberal leadership, becoming the first female party leader in Queensland.
