Ninth Island is an island, with an area of 32 ha, in south-eastern Australia. It is part of the Waterhouse Island Group, lying close to the north-eastern coast of Tasmania. It is partly privately owned and has been badly affected in the past by grazing, frequent fires and, in July 1995, by the Iron Baron oil spill which killed between 2000 and 6000 Little Penguins.[1] The island forms part of the Ninth and Little Waterhouse Islands Important Bird Area (IBA), so identified by BirdLife International because it holds over 1% of the world population of Black-faced Cormorants.[2]
As well as the Black-faced Cormorants, recorded breeding seabirds and waders include the Little Penguin, Short-tailed Shearwater, Common Diving-Petrel, White-faced Storm-Petrel, Pacific Gull, Silver Gull, Sooty Oystercatcher and Crested Tern. Cape Barren Geese also breed there, European Rabbits have been introduced and the Southern Grass Skink is present.[1]
