Cloncurry in north-west Queensland is where the ultimate battle between Brains and Brawn begins. As soon as the castaways hit the red dirt, it's every man for themselves to win the first reward challenge.

It's a new day, settling into camp, Sleeping rough has taken it's toll. With Immunity Idols hidden around both the Brains and Brawn camps, the race is on for Castaways to get their hands on them first.

Cracks and alliances have started to appear in both the Brains and Brawn camps. The split amongst one Tribe is evident at Tribal Council but with a hidden Immunity Idol at play, will things go to plan?

After last Tribal Council, the minority group in the Brawn Tribe realize they're in a dangerous position and work to better their alliances. Then, at a tense Tribal Council, one Castaway is eliminated.

One lucky Castaway who currently holds an immunity idol finds another. And later, battlelines are drawn at another intense Tribal Council, that lands on a surprising outcome.

Both Tribes begin to struggle with the harsh reality of the Aussie outback. Tensions are high and tears are shed at an emotional Tribal Council. But all is not what it seems.

Our hungry Castaways walk into the BBQ Feast Reward Challenge. Then, when one Tribe enters the ring for the Immunity Challenge, tensions flair with a Castaway forced to sit out and watch how it's done.

Tongues start to wag in both camps with ousted Castaways revealing who is in possession of Hidden Immunity Idols, hoping to flush them out. Then, it's blindside time at Tribal Council.

When winning Reward also doubles as winning Immunity, all bets are off, especially when the winners will also score champagne and bar snacks. With both Tribes attending Tribal Council, fireworks ensue.

One Tribe thinks they have it in the bag, but a surprise outcome means full bellies and a good night's sleep for the overall winners. With firm alliances rearing their head at a heated Tribal council.

Even when you think your private conversation won't be heard by others, it almost always is. The other Castaways use the overheard information to their advantage amongst their own Tribal alliance.

Desperation is setting in on one Tribe with members gunning for one person in particular. Now to flush their idol! And a good old fashioned blindside sees one Castaway scratching their head.

It's the moment the remaining Castaways have been waiting for, Tribe merge! Not everyone knows who to trust and with a couple of Idols in play, tonight's Tribal Council is anyone's game.

In an Immunity Challenge with a twist, there are three Immunity Idols up for grabs. Whoever scores one will see Tribal Council will swing in their favour...or will it?

The Immunity Challenge tests our hangry Castaways on spelling and balancing, with a challenge beast setting their eyes on the prize. Plus, At Tribal Council, a double agent is outed!

Tensions within Brawn start a double blindside, but there's an importance in a blindside of picking the right target at the right time.

It's Day 34 in the Australian Outback, and the feeling at camp is excitement for Brains, who now rule the camp. The biggest KEY to playing Survivor is to keep your closest allies safe.

George and Cara have stuck by each other through thick and thin, however, when the rest of the Tribe realise, will the King and Queen of Survivor's reign be over?

George survives tribal by the skin of his teeth to regain the majority, but his ability to stay in the game lies in the hands of one person, Wai.

Dani and Flick are on the bottom of the pack, but they are two strong physical and social threats who are here to fight. Will George's kingdom crumble under the persuasive powers of the remaining Brawn?

Dani concedes that the only way to get ahead in this game is to exploit some cracks in the majority alliance, but that would mean trusting someone who has betrayed her in the past.

Day 44, The four former brains have formed an impenetrable alliance leaving Flick, the only remaining brawn on the outer. Little do they know she's getting ready to shake things up!

As we near the end of the competition, will the game's longest lasting power couple, finally have to turn on each other?

Who will outwit... outplay... and outlast the other to become the ultimate Sole Survivor in the final episode of Brains Vs. Brawn?
