Nearly two decades ago, Professor Fiona Wood was the face of Australia’s response to the Bali bombings – the single largest loss of life due to an act of terror in our national history. The plastic and reconstructive surgeon was the co-creator of a revolutionary burns treatment known as spray-on skin, which helped save the lives of many Bali bombings victims.

This October 12 will mark the 20-year anniversary of those attacks. In the intervening years, Wood has continued to drive groundbreaking research into burns trauma, developing a cream to take away scars, 3D skin printing and an "iKnife" that can tell the difference between living and dead skin cells.

“Accidents happen and lives change in an instant," Wood tells Amanda Hooton on this episode of Good Weekend Talks. "To be able to do this better, to reduce that suffering, remains my passion.”
