Mutton Bird Island is an irregularly shaped island, with an area of 44 ha, in south-eastern Australia. Its highest point is 40 m asl. It is part of the Mutton Bird Island Group, lying close to the southern end of the south-western coast of Tasmania. It is also part of the Southwest National Park, and thus within the Tasmanian Wilderness World Heritage Site.[1] The island is part of the Port Davey Islands Important Bird Area, so identified by BirdLife International because of its importance for breeding seabirds.
