Oceania Australia

Oceania (sometimes Oceanica) is a geographical, often geopolitical, region consisting of numerous lands?mostly islands and usually including Australia?in the Pacific Ocean and vicinity. The exact scope of Oceania is defined variously, with interpretations normally including Australia, New Zealand, New Guinea, and various islands of the Malay Archipelago. The term is also used by numerous authors and in many languages to define one of the continents. Originally coined by the French explorer Dumont d'Urville in 1831, Oceania has been traditionally divided into Micronesia, Melanesia, Polynesia, and Australasia. As with any region, however, interpretations vary; increasingly, geographers and scientists divide Oceania into Near Oceania and Remote Oceania. Most of Oceania consists of small island nations. Australia is the only continental country, by some definitions. Indonesia has land borders with Papua New Guinea, East Timor, and Malaysia. Oceania is one of eight terrestrial ecozones, which constitute the major ecological regions of the planet.
