Oceania

The cities of Oceania's Melanesian, Micronesian and Polynesian island nations: Fiji, Papua New Guinea, the Solomon Islands and Vanuatu's larger volcanic and continental islands; the Federated States of Micronesia, Kiribati, the Marshall Islands, Nauru and Palau's small coral atolls and islands north of the equator; and Samoa, Tonga and Tuvalu within the wider Polynesian triangle. Grouped as one heading here, distinct from Australia and New Zealand's own temperate-continent subregion, because each of the three source subregions held too few atlas cities on its own to clear this browse page's twenty-heading ceiling; the underlying UN M49 geoscheme still recognizes Melanesia, Micronesia and Polynesia as its own finer-grained tier one level down.
