The Hunter Island Group Important Bird Area comprises several islands in the Hunter and Trefoil Island Groups lying off the north-western coast of Tasmania, Australia.[1] The islands are:
Collectively, they have an area of 152 km2. They have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world populations of Cape Barren Geese, Short-tailed Shearwaters, Black-faced Cormorants, Sooty Oystercatchers and Pacific Gulls. The IBA also supports the critically endangered Orange-bellied Parrot on its migration route between Tasmania and mainland south-eastern Australia. Most of Tasmania's endemic bird species breed in the IBA.[2]
