The seven remaining contestants face challenges that involve fishing, spending the night on an island that was once a convict settlement, and escaping from the island on a raft that was built by other people in the group, before their knowledge of the Mole is again put to the test when they sit another computer quiz, where the person who has the lowest score is eliminated.

The five remaining contestants have to abseil to retrieve some flags from the face of the Gordon Dam, predict how one of them would behave in three scenarios and face a night-time interrogation from one of their own trying to find out what challenge they had performed, before they are again tested on what they have learned about the Mole through a computer quiz in which the person who receives the lowest score is eliminated.

The four remaining contestants compete in some sports against some champions of those sports, while trying to avoid going against the champion of their particular sport, are challenged to identify a celebrity that one of them had photographed in Melbourne with their permission, and have to perform some tasks, some relatively straightforward, others more unpleasant, with the spin of a roulette wheel deciding which task or tasks they must perform, before their latest knowledge about the Mole is tested by another computer quiz from which the person with the lowest score ...
