The East Kangaroo Island, part of the Big Green Group within the Furneaux Group, is a 157-hectare (390-acre) unpopulated limestone island with granite outcrops and dolerite dykes, located in the Bass Strait, west of the Flinders Island, in Tasmania, in south-eastern Australia.
Prior to its declaration as the East Kangaroo Island Nature Reserve, the island was previously used to graze sheep, with overgrazing causing severe erosion. The island is part of the Chalky, Big Green and Badger Island Groups Important Bird Area.
