What are the countries and capitals of Oceania?

Oceania is the smallest of all the continents . It is located south of the Pacific Ocean, west of the Indian Ocean and southeast of Asia. It has an approximate area of ​​8.7 million square kilometers, which represents only 5.9% of the total land surface on the planet.

88% of its surface is occupied by a single country, Australia. The remaining thirteen countries that make up the continent and the colonial territories of the region are distributed in the remaining 12%.

The total population of Oceania amounts to 42 million inhabitants, which represents only 0.5% of the world total. More than 90% of that population is concentrated in three countries: Australia, New Zealand and Papua New Guinea.
