Flinders Island is an island in the Investigator Group off the coast of South Australia approximately 32 kilometres (20 mi) west of mainland town Elliston. It was named by Matthew Flinders after his younger brother Samuel Flinders, the second lieutenant on HMS Investigator in 1802.
It is part of the Investigator Islands Important Bird Area and has a colony of little penguins, but has suffered from the feral cats, black rats and mice, which threaten the bird life. The island is privately owned and was used mostly for farming since 1911, although that tailed off as transport costs rose. In 2020 the owners signed an agreement with the Government of South Australia which places a conservation agreement over 3,400 hectares (8,400 acres), which is most of the island.
The island has been subject to diamond exploration following the discovery of a wide range of kimberlite indicator minerals there, which was continuing as of 2019[update].
