Nigger Head

Nigger Head is a small island in the northern part of Shelburne Bay in far north Queensland, Australia about 30 km north of Cape Grenville, Cape York Peninsula in the Great Barrier Reef Marine Park Queensland, Australia. It is named so because it is an isolated coral outcrop; such outcrops were previously known as niggerheads by British sailors.
