This is a list of sovereign states and dependent territories in Oceania. Although it is mostly ocean and spans many continental plates, Oceania is often listed with the continents. This list follows the boundaries of geopolitical Oceania, which includes Australasia, Melanesia, Micronesia and Polynesia. The main continental landmass of Oceania is Australia. The boundary between Asia and Oceania is not clearly defined. For political reasons, the United Nations considers the boundary between the two regions to be the Indonesian-Papua New Guinean border. Papua New Guinea is occasionally considered Asian as it neighbours Indonesia, but this is rare, and it is generally accepted to be part of Oceania. Geographically, Papua and West Papua provinces are part of Oceania.
