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. 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.
