The Cocos (Keeling) Islands (Cocos Islands Malay: Pulu Kokos [Keeling]), officially the Territory of Cocos (Keeling) Islands (Cocos Islands Malay: Pulu Kokos [Keeling]), are an Australian external territory located in the Indian Ocean, comprising a small archipelago approximately midway between Australia and Sri Lanka and relatively close to the Indonesian island of Sumatra. The territory's dual name (official since the islands' incorporation into Australia in 1955) reflects that the islands have historically been known as either the Cocos Islands or the Keeling Islands.
The territory consists of two atolls made up of 27 coral islands, of which only two – West Island and Home Island – are inhabited.
