The Robbins Passage and Boullanger Bay Important Bird Area is a 238 km2 tract of land at the western end of the north coast of Tasmania, south-eastern Australia.
The site encompasses all the mudflats around Robbins Island, extending eastwards around Perkins Bay to North Point.
[1] It is adjacent to the northern end of the North-west Tasmanian Coast Important Bird Area in the west.
[1] The site has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of red-necked stints, double-banded plovers, pied and sooty oystercatchers, and a population of hooded plovers.
[1] The saltmarsh and fringing farmland provide habitat for critically endangered orange-bellied parrots on migration, as well as flame robins and many of Tasmania's endemic bird species.
