Sugarloaf Rock (Mutton Bird Group)

Sugarloaf Rock is a steep, rocky unpopulated islet located close to the south-western coast of Tasmania, Australia. Situated some 2 km south of where the mouth of Port Davey meets the Southern Ocean, the 3.56 ha islet is one of the eight islands that comprise the Mutton Bird Islands Group. Sugarloaf Rock is part of the Southwest National Park and the Tasmanian Wilderness World Heritage Site.

Fauna
The island is part of the Port Davey Islands Important Bird Area, so identified by BirdLife International because of its importance for breeding seabirds. Recorded breeding seabird and wader species are the short-tailed shearwater (15,000 pairs), fairy prion (2000 pairs), silver gull and sooty oystercatcher. It is a haul-out site for Australian fur seals.
