Fraser Island is divided into six parishes, listed as follows, from North to South (a seventh parish of County of Fraser, namely Dayman, is not located on Fraser Island, but on Big Woody Island and nearby smaller islands):
Some nearshore islands off the southern west coast and thus in the Great Sandy Strait also belong to the County of Fraser, specifically to its southernmost parish, Talboor. Among them are Slain Island, Tooth Island, Roundbush Island, Moonboom Island, Gardner Island, Dream Island, Stewart Island, and the Reef Islands.
