Summary The Betsey Island IBA harbours over 1% of the global population of Short-tailed Shearwater, Black-faced Cormorant and Little Penguin.
Site description Betsey Island and Little Betsey Island are located just off the south-east coast of Tasmania between Tasman Peninsula and Bruny Island. Betsey Island (175 ha) has steep rocky cliffs on the east, south and west sides and a small rocky beach on the north. The west side has a gentler slope gradient and open sandy terrain which is more suitable for burrowing birds. Open woodlands consisting of Tasmanian Blue Gum cover most of the island. The main rock type is dolerite with some sandstone outcrops in the north-east. Little Betsey Island (0.75 ha) is a steep sided rock with a platform on the top. Old remains of buildings can be found from when the island was farmed (Brothers et al. 2001).
