Summary These small islands support more than 1% of the world population of Cape Barren Goose, White-faced Storm-Petrel, Short-tailed Shearwater, Black-faced Cormorant, Sooty Oystercatcher and Pacific Gull and may still have nesting Fairy Tern (vulnerable). The near threatened Flame Robin has been reported.

Site description This IBA consists of the important islands in Franklin Sound, between Flinders Island, and Cape Barren Island off north-east Tasmania. These include Woody (=Anderson), Tin Kettle and Vansittart, which are important for Cape Barren Goose, and some smaller intervening islands which support large numbers of Short-tailed Shearwater (Little Dog Island, Great Dog Island, Little Green Island, Puncheon Island, Pelican Island), White-faced Storm-Petrel (South-east Great Dog Islet and Spences Reefs) and/or Pacific Gull (Neds, Oyster Rocks, Mid Woody Islet, Briggs Islet, Ram Island). Woody (=Anderson) Island is 166 ha of Crown Land with little value for bird species other than Cape Barren Goose. It is joined at low tide to Little Anderson Island, which is 13 ha of Crown Land. Mid Woody Islet is a 0.7 ha low grass and herb covered island of Crown Land. Tin Kettle is 176 ha of Crown Land with introduced pasture grasses and scrub and which is leased as a farm. Oyster Rocks is a 5 ha rocky Conservation Area. Neds Reef is 3 ha of granite islets on Crown Land. Little Dog is a 83 ha Game Reserve leased for harvesting of shearwater, dominated by ungrazed Poa poiformis grassland. Great Dog is a 354 ha privately owned grazing island with forest remnants amongst grassland. Briggs Islet is a 3.4 ha grassy Conservation Area. Little Green island is a 87 ha Conservation Area with a private lease for farming and shearwater harvesting. Spences Reefs is 0.65 ha of Crown Land. Ram Island is a 1 ha grassy private property. Puncheon Island is a 18 ha private property used for grazing. Pelican Island and Pelican Reef are collectively 7 ha of grassy and rocky Crown Land. Vansittart Island is a 807 ha private and leasehold island used for cattle grazing and has some scrub and forest remnants. Cape Barren Geese use these islands as they have short grassland herbage suitable for grazing, not dense tussocks which cover many other nearby islands. In the non-breeding season, most geese move to agricultural land on Flinders Island where a total of 5000-10,000 geese can be found in the Australian summer. The geese are distributed unpredictably across Flinders Island depending on the distribution of agricultural crops suitable for grazing. Licences to shoot small numbers of birds are issued in January/February to move remove birds from sensitive crops; these fields have not been designated as an IBA. Great Dog is a developing Indigenous Protected Area project.
