Radisich was also a member of the Senior Debating Team and a participant on numerous committees including the Student Council, Common Room and Amnesty International.

She was juggling these commitments with the final year of her degree when she won pre-selection to contest the theoretically safe Liberal seat of Swan Hills as the Labor candidate for the 2001 state election.

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.

The committee recommended a new way forward in support of consumer information about the food we eat that is grown, farmed or fished in WA by way of a voluntary state of origin certification and marketing program.

However, after reports stating that she would likely lose in any preselection contest for West Swan to Rita Saffioti, the chief of staff to Premier Alan Carpenter, she announced that she would retire from politics at the next election.

Graham Giffard, a then-sitting MLC, won Labor Party pre-selection for Swan Hills and lost the seat to the Liberal candidate Frank Alban in the 2008 election.

She formed a partnership between COSBOA, Telstra and the Federal Government to deliver information to small businesses about new, modernised awards following the introduction of the Fair Work Act in July 2009.

Radisich underwent Sonodynamic, Photodynamic, P53 Gene, Ozone and Dendritic Cell therapies in Xi'an, China from October til December 2011.
