How we count Oceania

We count the fourteen sovereign states of Oceania: Australia and New Zealand, plus the Pacific island nations of Melanesia, Micronesia and Polynesia. Many Pacific islands are territories or freely associated states that are not full UN members — for example the Cook Islands, Niue, and territories such as French Polynesia, New Caledonia and Guam — and these are not counted. All fourteen listed here are UN member states.

FAQ

What is the largest country in Oceania?
Australia is by far the largest country in Oceania by both area and population — it makes up the great majority of the region.
What is the smallest country in Oceania?
Nauru is the smallest country in Oceania by area, at about 21 square kilometres, and Tuvalu is among the smallest by population. Both are among the smallest countries in the world.
Is Australia a country or a continent?
Both terms are used. Australia is a single sovereign country, and it is also the mainland of the Australian continent. In the seven-continent model, Oceania is the wider region that includes Australia and the Pacific islands.
Why are the Cook Islands and Niue not counted?
The Cook Islands and Niue are self-governing states in free association with New Zealand, but they are not UN member states, so they are not in this count of 14.

Antarctica has 0 countries — it is governed by the Antarctic Treaty, not by any sovereign state.
