This IBA includes all of the extensive intertidal mudflats up to the high-tide line around Robbins Island, extending east around Perkins Bay to North Point, in north-west Tasmania. This includes fringing saltmarsh, and it could be extended further to include coastal farmland which is likely to support Orange-bellied Parrots on migration. It also includes the small Petrel Islands, the large Walker Island and small coastal areas of north and south-east Robbins Island which support large numbers of Short-tailed Shearwater. This contains the largest area of tidal mud and sandbanks in Tasmania as well as a series of islands and tidal channels, beaches and estuaries. The IBA is the most important shorebird site in Tasmania, with more than 25,000 shorebirds (about 75% migratory) during summer months, and is probably a major migratory staging point. Harvesting of Short-tailed Shearwater is permitted within Petrel Islands Game Reserve.
