The Indigenous peoples of Oceania are Aboriginal Australians, Papuans, and Austronesians (Melanesians,[note 1] Micronesians, and Polynesians).
With the notable exceptions of Australia, New Zealand, Hawaii, New Caledonia, Guam, and Northern Mariana Islands, indigenous peoples make up the majority of the populations of Oceania.
Australia and most of the islands of the Pacific Ocean were colonized in waves of migrations from Southeast Asia spanning many centuries.
A few habitable Pacific islands were never found until Europeans entered the ocean – they rank as amongst the last places on earth discovered by humans.
[16] The European proportion are not recent immigrants, but rather descendants of early settlers, as the islands were not always within the sphere of Japanese colonial influence.
[18] Islanders primarily speak Japanese, and like with those in the eastern Pacific, they could be interpreted as one of the smaller linguistic groups in Oceania.
New Zealand retains indirect rule over Niue and Tokelau and has kept close relations with another former possession, the Cook Islands, through a compact of free association.
The Aboriginals of Australia, the Māori of New Zealand and the native Polynesians of Hawaii, despite movements demanding more cultural recognition, greater economic and political considerations or even outright sovereignty, have remained minorities in countries where massive waves of migration have completely changed society.
In short, Oceania has remained one of the least completely decolonized regions on the globe.In New Zealand, according to the 2018 census, 16% of the population identified as being of Māori descent.
However, several conflicts and disputes concerning land use and resource rights continue between indigenous groups, the government and corporate entities.
Migrants from areas such as the Federated States of Micronesia have also faced discrimination in Guam itself, despite both being ethnoculturally Micronesian.
Australia's Polynesian population consists of Māoris, as well as immigrants who originate from the same countries as the ones who migrated to New Zealand.
