How Many Countries Are in Oceania?

Oceania has 14 sovereign countries: Australia, Fiji, Kiribati, Marshall Islands, Micronesia, Nauru, New Zealand, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu. Australia dominates the region in both area (7.7 million km²) and population (over 26 million). Many Pacific island nations are among the world's smallest and most remote. Several of these nations face existential threats from climate change and rising sea levels — Tuvalu, Kiribati, and the Marshall Islands are at particular risk. The broader Pacific region also includes territories of France, the United States, New Zealand, and the United Kingdom.
