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.

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 a major alliance crumbles, one tribe scrambles to avoid elimination. The other tribe grows frustrated with two members and make moves to have them removed next.

Tensions run high as the castaways endure further wind and rain without fire and shelter before a lengthy immunity challenge finishing with the next 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.

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?
