A puzzling jailbreak challenge ends in a nail-biting finish. The next day, the players face a new mind game that pits them against each other.

The players have an opportunity to get to know each other better on a trip to the Great Barrier Reef, where they set out for a treasure hunt at sea.

One person makes a decision that shocks the others before an elimination with a surprise twist. During an Outback bank heist, some players melt down.

If three teams can move fast, a mail delivery mission could boost the prize pot. Lunch puts one player in the hot seat.

A high-stakes climb through the Blue Mountains pushes the players physically and mentally, and begins to shift suspicion onto some new targets.

The six players remaining after another elimination head to Sydney, where they'll need to spot subtle differences between genuine and fake.

One person points fingers, but is it all misdirection? The players piece together clues and watch each other like hawks during a mission in Sydney.

With the end in sight and no one left to trust, the four remaining players in the game bundle up for a grueling trek across the Snowy Mountains.

The final three players go into stealth mode for the last mission before a quiz that will reveal the truth: Who is the winner, and who is The Mole?
