Swan Hills was held by a sitting Liberal minister in the Court government, June van de Klashorst, and in the leadup to the poll, there was little sign that she was in any danger of losing the seat. In a major upset, the Labor vote increased enough that Radisich was able to narrowly defeat van de Klashorst with the assistance of Liberals for Forests and One Nation preferences. She became the second-youngest person, and the youngest woman, to be elected to the Western Australian parliament.
