24 Australians arrive on the tropical island of Samoa ready to outwit, outplay and outlast each other in order to win the half a million dollar prize and the title of sole survivor.

As both tribes appear to reach their wits' end, the prospect of a luxurious and cleansing reward could be enough to keep the castaways in the game for weeks to come.

Social divisions begin to exhaust castaways as one tribe breaks down ahead of the next immunity challenge. Will they be able to come together to avoid another visit to tribal council?

Winning immunity has never been so vital to resettling the balance within each tribe, and with a highly competitive challenge that encourages fair contact, things are sure to get feisty.

Blatant lies at the last tribal council has put everyone in one camp on edge. Will they be able to put their differences aside to win the reward challenge or will they leave hungry?

A brutal tribal council the night before has left one castaway on the war path seeking retribution. At the immunity challenge the tribes must take part in a physical Sumo'an contest.
