Thousands of individuals responded, and these ten were the ones that were chosen: Arrival Game: The players met up in five different locations in Sydney, in pairs, each of them near a phone.
They in turn gave the assignment's directions to Shaun and Petrina, who had to find their puzzle on another phone box and enter it into the safe, which was inside a car.
Alison, Petrina, and Josh failed to open their safes, but the other four who jumped all remembered their numbers, putting the group $1,000 ahead for this assignment.
If the team decided someone's heart rate was hopelessly too high, they could pull them out, but it would incur a 10-minute penalty, and all time that was taken to that point would also count.
They were put into pairs, with one hanging from a helicopter and dropping a flour bomb on a target being towed by a boat 40 meters below them, with the other in the chopper instructing the pilot.
The women completed their task quickly, but Nikki, who was doing the bulk of the diving, pulled up several duplicates that resulted in penalty minutes.
The next task was for Cam and Petrina (and subsequently Nathan and Alison, and Josh and Nikki from the groups of three) to take a photo wearing one another's clothes, except for underwear.
All of Josh, Nikki, and Shaun's pictures counted, but the local that Nathan, Kris, and Alison recorded singing "Waltzing Matilda" was clearly under the age of 18.
They met the host in a second-floor room at their hotel and were told to ask Josh repeated yes/no questions to help discern his location.
The first was when the car, en route to the cultural center, stopped at a corner store, two Girl Guides approached it and asked for a donation.
The players chose Kris, and she was given the opportunity to search for coins buried in the beach with a metal detector, and if she could accumulate 2,000 CFP Francs, she could rent a kayak and row out to the rescue boat and win the $5,000 that way.
Kris and Petrina again got it pretty easily from the SMS, but had to describe their drawing to Nathan and Nikki twice, and time ran out just as Cam and Shaun got their fax.
All those players after him who tried the plank (Shaun and Kris refused to even try) took a different technique than Nathan had – the first of them, Alison, grasped her safety wire tightly, which gave her more balance, and made it very easy to make it out to the red wallets.
Cam and Nathan took most of the turns standing under the ball, with Shaun and the women each refusing to take more than a small number of early ones and sleeping through the rest of the assignment.
Underwater Charades: The group picked their two strongest swimmers, Cam and Nathan, and their two biggest movie buffs, Shaun and Petrina.
Alison and Kris, the two unchosen, stayed with the host and had the assignment revealed to them – Cam and Nathan would be in snorkeling gear in the hotel's pool acting out the titles of television shows and films in which some character dies.
Once Alison and Kris correctly guessed the charade, they'd radio the title to Shaun and Petrina, who were standing by in a mock cemetery and had to dig up the grave of the actor who portrayed the character that died in the particular film or TV show.
Alison and Kris correctly guessed five charades – South Park, Crouching Tiger, Hidden Dragon, Titanic, What Lies Beneath, and Pearl Harbor (failing to guess American Beauty), but Shaun and Petrina only dug up four correct caskets, thinking Ben Affleck's character died in Pearl Harbor when it was in fact Josh Hartnett's that did.
They refused again, and neither of the last caskets had the money either – it was in Josh Hartnett's grave, the one that Shaun and Petrina failed to identify as a correct one.
This assignment also brought about a major plot point in the season – when returning to the paddy wagon after being interviewed, Shaun found a note that was seemingly a communication between the show's producers and the Mole.
She was to fly in a restored World War II fighter plane and observe planks the others laid out on the beach, which would show answers to questions the host asked.
The first three rounds were worth $2,000 if the player was successfully found, but none of them were, with each giving a surprising answer to one of their questions – Nathan said he would strip nude for a bachelorette party for $250, Cam said he would not help out a stranger being assaulted, Shaun said he would sleep with his best friend's girlfriend, and Petrina said she would date a married man.
Helicopter Jigsaw: The host called the players at their breakfast table and told them to find him, for $20,000 that would be reduced by $1 for each second that passed until they found him.
It instructed them to head to the Amédée Lighthouse (where Josh was held hostage in the fourth episode) for the remaining pieces to the puzzle.
They were unable to fully solve this without buying an additional clue that told them that the light would only turn on if two of them were lying in the hammocks and one looking at the table.
The following acts of sabotage were revealed in the final episode: Arrival Game: Petrina thought Shaun would be least likely to know the Melbourne GPO Postal Code offhand, so she purposely gave him the wrong answer and they were unable to open their safe, costing $1,000.
Dam Relay Race: Petrina needlessly exerted herself before going on the high wire, taking quick sharp breaths that spiked her heart rate.
She had been carrying a blank memory chip with her the entire day, and noted how the risk of this gambit was magnified when part of the assignment involved Cam having to wear her clothes.
Parking Lot: Petrina was instructed to quickly solve the easier car puzzle, to goad the others into taking the much harder one and gamble away their $5,000 winnings.
This cost the group $5,000, but Petrina very nearly gave the game away, because she had a note of instructions from show's producers tucked under the short denim skirt she was wearing that day, and in all the running around it nearly came loose.
