Located on the western side of Admiralty Gulf and a part of the Bonaparte Archipelago, the island encompasses an area of 2,361 hectares (5,834 acres).[1] It is part of the Osborn Island group, which includes South West Osborn, Borda, Carlia, Steep Head and Kidney Island as well as West, North and Centre Rock.

The island is a volcanic plug.[2]

The traditional owners of the area are the Uunguu peoples of the Wunambal language group, whose name for the island is Ngurraali.[3]

The group was named in 1891 by Phillip Parker King after John Osborn, one of the Lords of the Admiralty.[1]

The air-breathing land snails, Kimberleymelon tealei and Carinotrachia admirale are both endemic to the island.[4]

In 2008 a boat carrying refugees that had travelled via Indonesia arrived at the island. The then immigration minister, Chris Bowen was attacked by the opposition over his "porous border protection policies".[5] Another boat arrived in 2010 with only two passengers and one crew on board.[6]
