In a world-first, this program has pitted 12 giants of Australian society against 12 everyday Aussies in order to create one epic battle: champions versus contenders.

The game starts to become very real for the castaways. The reality of having to catch their own food and create a liveable shelter becomes top priority in camp.

In the Champions camp a new leader steps forward and starts calling the shots, while over at The Contenders it's a case of the boys versus the girls.

Reeling after a shocking outcome in Tribal, one tribe is very unsettled and new targets start to come under fire.

A castaway who has been struggling with the game becomes determined to stick with the fight. While one of the Contenders struggles with an injury so serious, it could spell the end of their game.

From illness to dummy spits, time in isolation is starting to take its toll on some of the Castaways and it's causing unease in the camps.

After a surprising tribal council result, some castaways realise they're on the outer and start to scramble to make alliances within their tribe.

The twist in the previous game has one tribe torn and plotting new strategies to kick out one of the biggest competitors in the game.

The game steps it up a notch when two castaways who have been on the edge of their team come face-to-face in front of their tribe.

After losing at an endurance challenge for immunity, one team enters in what looks to be the fiercest Tribal Council yet.

After 25 days on the island, the castaways have made the halfway point in the game, and their chance of becoming Sole Survivor is getting closer and more obtainable.

After a massive shake-up in the game, both tribes are cautiously reforming plans and forging new alliances.

As the game heats up with a merger, some islanders are starting to struggle, while others are just beginning to orchestrate their big moves. One of the program's biggest threats will be cut loose.

It's auction time. The hungry castaways are given $500 each to enter into a new kind of battle where food is the hottest property in town.

Mat and Robbie have faced off time and time again, but is it time to send one of them home?

The end game is getting closer. Hold your breath! Contenders will rise and champions will fall. The big players make their move.

The end game is getting closer and the scramble for survival more desperate, sparking the hunt for idols. Later, at a massive Tribal Council, one player's confidence just might cost them the game.

After an unexpected result at Tribal Council, the Castaways' Camp is a hive of animosity and distrust. Hard truths come to the surface and split the opinions of the tribe.

With only seven castaways that still remain, the game's power rests with one, and it's not who you think. What Monica is about to do next really shakes things up.

With bitter grudges in play, victory at an immunity challenge has never been more important. At Tribal Council, accusations fly as some tribe members are accused of being carried through the game.

As the game comes close to the end, the taste of victory is closer than ever. Trust between the castaways is at an all-time low and a bold move is made by a player to gain further power.

As the pointy end of the game closes in on the remaining five castaways, one player seeks revenge after the previous tribal council.

With only a few days left in the game, physical strength dwindling and emotions at an all-time high, the castaways are granted an opportunity for immunity, thus securing their place in the final three.

After 50 testing days, the remaining three castaways can finally see and feel the eagerly anticipated finish line ahead of them, with one of the greatest battles for immunity in front of them.
