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.

Aligned castaways find themselves at each other's throats over who is doing enough work around camp, but is one player acting lazy to divide the tribe?

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?

A surprise challenge sees one castaway return to camp with an unexpected power that could push tensions to breaking point. Later, will one castaway past come back to haunt them at 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.
