The top three only have one day of challenges left to impress the judges, and they will need to pull out all stops to make it into the final round of the competition. In Sydney Natalie is going extreme with jet boat rides and a walk in the clouds. Heather in Hobart is tackling a mountain on bike, and on Hamilton Island Suzie explores the Great Barrier Reef from the water and sky. All of the crews converge on the Gold Coast and another girl is eliminated, revealing the top two.
