The eleven remaining teams go to Australia where they first enter Geelong Prison and must escape by using various methods possible. Both the ice dancers and the police cadets get a Boomerang (which sends back a team to repeat the previous challenge) and use it on each other. The Stepbrothers finally begin to get along while Carrie tries to reveal her feelings for Devin, who later finds out his girlfriend has broken up with him. In the end the Ice Dancers beat out the Cadets for last place, but another non-elimination round saves them.
