Oceania

Oceania is a geographical region that is described as a continent in some parts of the world. It includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern and Western Hemispheres, Oceania is estimated to have a land area of 8,525,989 square kilometres (3,291,903 sq mi) and a population of around 44.4 million as of 2022. While in most of the English-speaking world Oceania is described as a geographical region, outside of the English-speaking world Oceania is described as one of the continents. In this model of the world, Australia is only seen as an island nation contained inside of the continent of Oceania, and not a continent by itself. When compared to the other continents, Oceania is the smallest in land area and the second least populated after Antarctica.
