The geography of New Caledonia (Nouvelle-Calédonie), an overseas collectivity of France located in the subregion of Melanesia, makes the continental island group unique in the southwest Pacific. Among other things, the island chain has played a role in preserving unique biological lineages from the Mesozoic. It served as a waystation in the expansion of the predecessors of the Polynesians, the Lapita culture. Under the Free French it was a vital naval base for Allied Forces during the War in the Pacific.
The archipelago is located east of Australia, north of New Zealand, south of the Equator, and just west of Fiji and Vanuatu. New Caledonia comprises a main island, Grande Terre, the Loyalty Islands, and several smaller islands. Approximately half the size of Taiwan, the group has a land area of 18,575.5 square kilometres (7,172.0 square miles). The islands have a coastline of 2,254 km (1,401 mi). New Caledonia claims an exclusive fishing zone to a distance of 200 nmi or 370 km or 230 mi and a territorial sea of 12 nmi (22 km; 14 mi) from shore.
