Oceania (sometimes Oceanica[1]) is a geographical, often geopolitical, region consisting of numerous lands—mostly islands in the Pacific Ocean and vicinity. The term is often used in many languages to define one of the continents[2][3][4] and is one of eight terrestrial ecozones.
Ethnologically, the islands that are included in Oceania are divided into the subregions of Melanesia, Micronesia, and Polynesia.[5]
The exact scope of Oceania is variably defined: it generally includes New Zealand, is often taken to include parts of Australasia such as Australia and New Guinea, and sometimes all or part of the Malay Archipelago.[Originally coined by the French explorer Dumont d"Urville in 1831, Oceania has been traditionally divided into Micronesia, Melanesia and Polynesia. As with any region, however, interpretations vary; increasingly, geographers and scientists divide Oceania into Near Oceania and Remote Oceania.[9]
Most of Oceania consists of island nations composed of thousands of coral atolls and volcanic islands, with small human populations.
Australia is the only continental country but Indonesia has land borders with Papua New Guinea, East Timor, and Malaysia. If the Australia-New Guinea continent is included then the highest point is Puncak Jaya in Papua at 4,884 m (16,024 ft) and the lowest point is Lake Eyre, Australia at 16 m (52 ft) below sea level.
