Oceania is a geographic region that includes Australasia, Melanesia, Micronesia, and Polynesia. It has a land area of 8,525,989 square kilometers (3,291,903 sq mi) and a population of about 41 million people, spanning the Eastern and Western Hemispheres. Oceania is the smallest continent in land area and population after Antarctica. Oceania’s economies range from the highly developed and globally competitive financial markets of Australia, New Caledonia, and New Zealand, which have high quality of life and human development indexes, to the much less developed economies of Papua New Guinea, Indonesian New Guinea, Kiribati, Vanuatu, and Tuvalu, as well as the medium-sized economies of Pacific islands like Palau, Fiji, and Tonga. Australia is Oceania’s largest and most populated country, with Sydney as its capital.
