The region includes the four independent countries of Fiji, Vanuatu, the Solomon Islands, and Papua New Guinea. It also includes the French special collectivity of New Caledonia and parts of Indonesia – notably Western New Guinea, which is the Indonesian part of the island of New Guinea. Almost all of the region is in the Southern Hemisphere; only a few small islands that are considered part of Oceania — specifically the northwestern islands of Western New Guinea — lie in the Northern Hemisphere.
