Little Green Island is a granite island, with an area of 87 hectares (210 acres), in south-eastern Australia. It is part of Tasmania’s Great Dog Island Group, lying in eastern Bass Strait between Flinders and Cape Barren Islands in the Furneaux Group. It is partly a conservation area, and partly private property, used for grazing livestock. The island has been degraded by repeated burning and grazing. Commercial muttonbirding took place until 1957, and recreational muttonbirding since then.
