Summary The Maatsuyker Island Group supports more than 1% of the world population of Short-tailed Shearwater (about 1.5 million pairs), Fairy Prion and Black-faced Cormorant, as well as thousands of pairs of Common Diving-Petrel and Little Penguin.
Site description This IBA consists of the whole Maatsuyker group of islands, which about 10 km off Red Point in Southwest National Park, Tasmania. The IBA includes De Witt Island, Maatsuyker Island, Ile du Golfe, Hen Island, Flat Top Island, Round Top Island, Louisa Island, Walker Island, Flat Witch Island and Needle Rocks, but excludes Chicken Island. The islands selected for inclusion are largely undisturbed rocky islands with natural vegetation which varies from grass through forbs and ferns to Leptospermum-dominated scrub and eucalypt woodlands, depending on the degree of exposure: De Witt Island (515 ha, densely wooded with a 354 m summit), Maatsuyker Island itself (186 ha, well-known for its lighthouse and meteorology station, a Leptospermum-dominated island with weeds and other remnants of previous occupation and a 278m summit), Ile du Golfe (68 ha, scrubby limestone ridge), Hen (8 ha, pristine island), Flat Top (1.6 ha, with a short herby plateau surrounded by cliffs), Round Top (6 ha, pristine steep rocky island), Louisa (23 ha, wooded island separated from mainland by 250 m sand spit), Walker (15 ha, with stunted scrub) and Flat Witch (64 ha, shrubby) Islands and Needle Rocks (a series of rocks off Maatsuyker, five with birds, totalling 10 ha).

Other biodiversity Metallic Skink, Three-lined Skink, Tasmanian Tree Skink, Long-nosed Potoroo, Tasmanian Pademelon, Swamp Rat. More than 2000 Australian Fur Seals, mostly at Walker and Maatsuyker Islands and Needle Rocks; 130-140 New Zealand Fur Seal pups and small numbers of Southern Elephant Seal annually at Maatsuyker Island. Eastern Pygmy Possums on Little Witch and De Witt Islands. New Zealand Fur Seals breed on Little Witch. De Witt Island is dominated by eucalypt forest, and White (1981a) recorded 56 plant species despite deliberate burning of bird rookeries by fishermen.
Protection status Small part of the very large Southwest National Park (World Heritage Area).
