Australian Survivor is an Australian adventure 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 out of the game by their fellow castaways. The final castaway remaining is awarded the title of "Sole Survivor" and the grand prize of A$500,000.

The series first aired in 2002 on the Nine Network, who as of 2023, also hold the first-run Australian broadcast rights to the American edition of Survivor. In 2006, a celebrity edition aired on the Seven Network. Both iterations of the series only lasted one season due to low ratings.

In November 2015, Network Ten announced at its network upfronts that it would be reviving the series in 2016. The series commenced airing on 21 August 2016. Unlike its predecessors, Network Ten renewed the series for another season for 2017, and has continuously been renewed with success, with season's airing yearly. Most recently, Australian Survivor is aired the 12th season titled Brains V Brawn II set on the island of Upolu in Samoa, nearly 2025. In late 2024, the show was renewed for a shorter second edition for 2025, and the 13th season overall, titled Australia V The World also set in Samoa. The season will feature notable returning players from previous seasons competing against notable players from other versions of Survivor.
