Oceania (UK /ˌoʊʃɪˈɑːniə, ˌoʊsɪ-/[1] or US /ˌoʊʃiːˈæniə/)[2] also known as Oceanica[3] is a region centred on the islands of the tropical Pacific Ocean.[4] Opinions of what constitutes Oceania range from its three subregions of Melanesia, Micronesia, and Polynesia[5] to, more broadly, the entire insular region between Asia and the Americas, including Australasia and the Malay Archipelago.[6] The term is often used more specifically to denote a continent comprising Australia and proximate islands[7[8[9[10] or biogeographically as a synonym for either the Australasian ecozone (Wallacea and Australasia) or the Pacific ecozone (Melanesia, Polynesia, and Micronesia apart either from New Zealand[11] or from mainland New Guinea).[12] As an ecozone, Oceania includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, part of Philippines islands, Australia, the Solomon Islands, Vanuatu, and New Caledonia, constitute the separate Australasian ecozone. In geopolitical terms, however, New Zealand, the Solomon Islands, Vanuatu and New Caledonia are almost always considered part of Oceania, and Australia and Papua New Guinea are usually considered part of Oceania too. Sometimes Papua province in Indonesia may be included, as Puncak Jaya is often considered the highest peak in Oceania. dat ve may bay dai ly ve may bay ve may bay gia re vé máy bay
