Erith Island is a granite island, with an area of 323 hectares (800 acres), in south-eastern Australia. It is the second largest of Tasmania’s Kent Group, lying in northern Bass Strait between the Furneaux Group and Wilsons Promontory in Victoria. It is now part of the Kent Group National Park, Tasmania’s northernmost national park, which was gazetted in 2002. Erith was highly modified for cattle grazing and is mainly covered by exotic pasture.
