Steep Island, also known as Steep Head, is a 21.6 ha island in Bass Strait in south-eastern Australia.
It is part of Tasmania’s Hunter Island Group and lies between north-west Tasmania and King Island.
It was once used for grazing sheep but title has been transferred to the Tasmanian Aboriginal community; with an estimated 250,000 shearwater burrows present, it is principally used for muttonbirding.
[2] Breeding seabirds and shorebirds include little penguin, short-tailed shearwater, common diving-petrel, Pacific gull, silver gull, sooty oystercatcher and black-faced cormorant.
Tiger snakes have been introduced to the island and pose a threat to breeding seabirds.
