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. Australia and Papua New Guinea are usually considered part of Oceania along with the Maluku Islands and Papua in Indonesia. Puncak Jaya in Papua is often considered the highest peak in Oceania.
