Australian Survivor is an Australian reality game show based on the international Survivor format. Following the premise of other versions of the Survivor format, the show features a group of contestants, referred to as "castaways" as they are marooned in an isolated location. The castaways must provide food, water, fire, and shelter for themselves. The contestants compete in various challenges for rewards and immunity from elimination. The contestants are progressively eliminated from the game as they are voted off the island by their fellow castaways. The final castaway remaining is awarded the title of "Sole Survivor" and the grand prize of A$500,000.
