From Wikipedia, the free encyclopedia
Oceania, also known as Oceanica, is a geographical and geopolitical region consisting of numerous lands—mostly islands in the tropical Pacific Ocean and vicinity.[1][2] The term is often used more specifically to denote a continent comprising Australia and proximate Pacific islands.[3][4][5][6][7][8][9]

The boundaries of Oceania are defined in a number of ways. The narrowest definition is an ethnological division into its three subregions of Melanesia, Micronesia, and Polynesia.[10] The broadest definition is the entire insular region between Asia and the Americas, including Australasia and the Malay Archipelago.[11] Most definitions include parts of Australasia such as Australia, New Zealand, and New Guinea, and parts of Maritime Southeast Asia.[12][13][14]
'Oceania' is also biogeographically used as a synonym for either the Australasian ecozone (Wallacea and Australasia) or the Pacific ecozone (Melanesia, Polynesia, and Micronesia apart either from New Zealand[15] or from mainland New Guinea).[16]
