Summary Albatross Island & Black Pyramid Rock support about 40% of the world population of Shy Albatross and about 20% of the world population of Australasian Gannet. Numbers of Fairy Prion and Common Diving-Petrel are poorly known but very large.

Site description This IBA consists of two tiny islands offshore from the north-west of Tasmania. Albatross Island (33 ha) is very rocky, with a coastline of eroded boulders, gulches and caves and a short cover of grasses and herbs across the interior. Black Pyramid Rock (40 ha) is a spectacular basaltic rock surrounded by steep cliffs, steep grassy slopes and a small central plateau. It is sparsely vegetated as the gannets have taken most as nesting material.

Key Biodiversity Small numbers of Little Penguins, Short-tailed Shearwaters, Pacific and Silver Gulls and Sooty Oystercatchers nest. Records of Lewin's Rail at Albatross Island are noteworthy, when the decline of the endemic Tasmanian race brachipus gives cause for serious concern. Peregrine Falcon noted at Albatross Island and breeding at Black Pyramid Rock. Other species recorded from the IBA include the near threatened Flame Robin and the Australian cool/temperate biome-restricted Pink Robin.

Non-bird biodiversity: Australian Fur Seal and New Zealand Fur Seal regularly haul out at Albatross Island.
