The indigenous peoples of Oceania are Polynesians, Melanesians, Micronesians, Papuans and Australian Aborigines. With the notable exceptions of Australia, New Zealand, Hawaii, New Caledonia and Guam, indigenous peoples make up the majority of the populations of Oceania.
The term "Pacific Islanders" excludes Australian Aborigines, and may be understood to include non-indigenous populations of the Pacific Islands.
Both Australia and the islands of the Pacific Ocean were colonized in waves of migrations from Southeast Asia spanning many centuries. European and Japanese colonial expansion brought most of the region under foreign administration, in some cases as settler colonies which displaced or marginalized the original populations. During the 20th century several of these former colonies gained independence and nation-states were formed under local control. However, various peoples have put forward claims for indigenous recognition where their islands are still under external administration; examples include the Chamorros of Guam and the Northern Marianas, and the Marshallese of the Marshall Islands and the Native Hawaiians of Hawaii.
