The Torres Strait Islands are a group of at least 274 small islands in the Torres Strait, a waterway separating far northern continental Australia’s Cape York Peninsula and the island of New Guinea.
The Islands have been inhabited by the indigenous Torres Strait Islanders. Lieutenant James Cook first claimed British sovereignty over the eastern part of Australia at Possession Island in 1770, but British administrative control only began in the Torres Strait Islands in 1862. The islands are now mostly part of Queensland, a constituent State of the Commonwealth of Australia, but are administered by the Torres Strait Regional Authority, a statutory authority of the Australian federal government. A few islands very close to the coast of mainland New Guinea belong to the Western Province of Papua New Guinea, most importantly Daru Island with the provincial capital, Daru.

Only 16 of the islands are inhabited. The Torres Strait Islands’ population was recorded at 4,514 in the 2016 Australian census, with 91.8% of these identifying as Indigenous Torres Strait Island peoples. Although counted as Indigenous Australians, Torres Strait Islander peoples, being predominantly Melanesian, are ethnically and culturally different from Aboriginal Australians.
