Summary Stapleton Island has rarely been surveyed but has supported more than 1% of the world population of Brown Booby and Lesser Crested Tern.

Site description Stapleton Island is about 40 km east of Cape Melville in the northern Great Barrier Reef. It is designated as a Preservation Area, the strongest protection within the marine park, strictly regulating all access. It is an elongated narrow cay, about 500 m x 100 m at its widest. The cay is comprised of coral sand and reef rubble rising to a central sand ridge 5 m above sea-level. The outer fringe has a strand community of herbs and the sand ridge is dominated by Lepturus grass and stunted shrubs. Other neighbouring islands could be added to the IBA if further surveys indicate that they regularly support significant numbers of birds, notably Tydeman Cay (1 ha; 738 nests of Brown Booby in 1982) and Sandbank no1 (1 ha; 500 nests of Brown Booby in 1984).
