<P> About halfway through the game , the tribes are `` merged '' into a single tribe , and competitions are on an individual basis ; winning immunity prevents that player from being voted out . Most players that are voted out during this stage become members of the `` Tribal Council Jury '' . Once only two people remain , the `` Final Tribal Council '' is held where the remaining players plead their case to the members of the Jury as to why they should win the game . The jurors must then cast their vote for which finalist should be awarded the title of `` Sole Australian Survivor '' and the grand prize of A $ 500,000 ( or a A $100,000 charity prize in the celebrity season ) . </P>
