The Breaksea Islands Group is a group of six islands, located in the Southern Ocean, off the south western coast of Tasmania, Australia.[1]

Located near the mouth of Port Davey, the group comprise the North Breaksea and Main Breaksea Islands,[2] the Fitzroy, Kathleen, and Munday islands, and the Mavourneen Rocks. The group have a total area of approximately 16 hectares (40 acres) and are contained within the Southwest National Park, part of the Tasmanian Wilderness World Heritage Site and the Port Davey/Bathurst Harbour Marine Nature Reserve.[3]


The islands are noted as a breeding site for many seabird species, including little penguin (400 pairs), short-tailed shearwater (3-5000 pairs), fairy prion (20 pairs) and silver gull. The Tasmanian tree skink is present.[2] Rabbits were introduced in the 19th century by whalers.[4] and have caused some damage to vegetation and soil.[5]

The islands are part of the Port Davey Islands Important Bird Area, so identified by BirdLife International because of its importance for breeding seabirds.[6]
