Twelve contestants are plunged into a world of sabotage, suspicion and intrigue as they undertake confronting physical and mental challenges while competing for a potential prize of $250,000. In their first challenge, twelve players who have never met each other before are blindfolded and driven to three separate locations deep in the Stockton Sand Dunes on the NSW mid-North Coast. Little do they realise that every decision affects the overall pot of money. The next day, the contestants literally scale new heights when they must relay across a high wire twenty-stories above ground in a gully in the Blue Mountains.

Tonight we pick up with we're we left off last week - 20 stories high above a gully in the Blue Mountains. Will the Mole fail on purpose? Then, the contestants meet Shura near Mt Victoria in the Blue Mountains and split into two teams for Money Bags. Starting at opposite ends of a track, the teams must carry heavy money bags to meet at a nominated spots. Given 90 minutes, the contestants win nothing if they don't meet up. Later they meet in a maze of military forts at Middle Head in Sydney Harbour for Key To Comfort. They will be sleeping under the stars, but there will be a hunt to find 12 keys hidden amongst the fort.

After a night under the stars, friendships will no doubt be tested and nerves will be frayed - especially when they discover what is in store. After their 'glamping', the 12 contestants face their biggest fear yet. One-by-one, they answer 20 questions about who they think is the Mole. The person with the least amount of correct answers will be eliminated.

The contestants will feel the need for speed as a new week starts. One team will line obscure parts of Sydney Harbour and communicate clues to another team in a speed boat to spot an answer. The remaining contestants must then decipher the code, which has been written at high speed. And a surprise elimination will see our eleven contestant become ten.

Contestants storm Melbourne's Brighton Beach, with its iconic colourful Bathing Boxes for a treasure hunt. Then in an intense game of trust, with allegiances being exposed and destroyed, who is playing for themselves and who is playing for the group?

Just when the contestants least expect it, a past challenge comes back to haunt them. The fate of the contestants rests with one of their own and that one contestant holds all the power before someone is eliminated.

This challenge will leave our contestants feeling sky-high, and maybe a little dizzy, as they're introduced to the ride of their life in Aeroplane at an airfield near Geelong. The contestants meet at the iconic Luna Park in St Kilda where a game of 'Spot The Difference' highlights how important attention to detail is in The Mole. To round off the two weeks in Melbourne the contestants meet Shura at Flemington Racecourse for a Quiz and Termination. With the Melbourne Cup shimmering in front of them, each contestant will be hoping they avoid a red screen as nine contestants become eight.

The Gold Coast is full of life's high rollers and the group meets at the Peppers Broadbeach Skyhome for the highstakes gambling game of Let It Ride. Shura will deal a card from the pack, and the contestant can choose to hold it and walk away, or keep on getting Shura to deal cards - but they risk losing it all if a red Mole thumb print card is dealt.

The contestants meet to play the most devastatingly psychological game yet - Silent Auction. Then, they all head to iconic theme park Sea World, where Shura reveals they'll be diving alongside sharks.

The sharks are circling in the Quiz and the Termination, with the exemptions in full play, leaving a small number of contestants to battle it out before seven become six.

Tonight, contestants meet in the Bombo quarry near Kiama for their next challenge - 'Writing With Jeeps'.

The contestants meet Shura in the scenic seaside hamlet of Kiama for the game of 'Catapult'. Then a quiz and termination will see six contestants become five.

The five remaining contestants meet Shura at a scenic bush location to play a game called Cash Waterfall.

The final four contestants meet at an oval in Camden, west of Sydney, for the game Hourglass Maze. From the sweaty to the suave and sexy, the four contestants then get dressed to the nines as they walk the red-carpeted stairs of Sydney's Town Hall. The pressure is on, and the penultimate Quiz and Termination will reveal the final three contestants that will go through to the finale.

Contestants get a chance to interrogate each other in a lie detector test. Then, in the final quiz the question viewers have been dying to know: Who Is the Mole?
