Oceania is a geographical (often geopolitical) region consisting of numerous countries and territories – mostly islands – in the Pacific Ocean. The exact scope of Oceania is controversial, with varying interpretations including East Timor, Australia, New Zealand, or none of these.

For the oceans of the Earth, see Oceans.

Overview

The primary use of the term Oceania is to describe a continental region (like Europe or Africa) that lies between Asia and the Americas, with Australia as the major land mass. The name Oceania is used, rather than Australia, because unlike the other continental groupings, it is the ocean rather than the continent that links the nations together. Oceania is the smallest continental grouping in land area and the second smallest, after Antarctica, in population.

Countries and territories of Oceania

Image:Oceania-map.JPG Oceania has been traditionally divided into Micronesia, Melanesia and Polynesia (originally by the French explorer Dumont d'Urville in 1831). This subdivision is no longer recognised as correct by most geographers and scientists — who prefer to divide Oceania into Near Oceania and Remote Oceania — but it is still the most popular one.

Most of Oceania consists of small island nations. Australia is the only continental country, and Papua New Guinea and East Timor are the only countries with land borders, both with Indonesia.

The nations of Oceania have varying degrees of independence from their colonial powers and have negotiated a wide range of constitutional arrangements to suit their circumstances. The following list contains the countries and territories that are classified as part of Oceania by UNESCO; other countries are sometimes considered part of Oceania (see Other Interpretations below).

Australia

Melanesia

Micronesia

Polynesia

  1. Commonwealth Realms are independent constitutional monarchies in which Elizabeth II reigns as Queen
  2. See administrative divisions of France

Other interpretations of Oceania

  • Australia is sometimes not included in Oceania, although a term like Pacific islands would normally be used to describe Oceania without Australia
  • Hawaii and the United States territories with no indigenous population in the North Pacific are sometimes included, but are normally grouped with the United States in North America. Hawaiians are a Polynesian race.
  • Easter Island is a Polynesian island in the eastern Pacific Ocean, part of the territory of Chile, and is sometimes included in Oceania.
  • On rare occasions the term may be stretched even further to include other Pacific island groups such as the Aleutian Islands.

Oceania in ecology

Oceania is one of eight terrestrial ecozones, which constitute the major ecological regions of the planet. The Oceania ecozone includes all of Micronesia, Fiji, and all of Polynesia except New Zealand. New Zealand, along with New Guinea and nearby islands, Australia, the Solomon Islands, Vanuatu, and New Caledonia, constitute the separate Australasia ecozone.

Population density

This is a list of countries/dependencies by population density in inhabitants/km².

Unlike the figures in the country articles, the figures in this table are based on areas including inland water bodies (lakes, reservoirs, rivers) and may therefore be lower here.
