Oceania is the smallest continent in terms of land area and population. It covers about 8.5 million km², which is roughly 6% of the Earth’s land surface. In 2025, the region was home to around 45 million people, representing less than 1% of the world’s population.
The continent includes Australia, New Zealand, and thousands of islands across the Pacific Ocean, commonly grouped into Melanesia, Micronesia, and Polynesia. Population distribution varies greatly, from the vast, sparsely populated interior of Australia to densely inhabited island states and urban areas such as Sydney and Auckland.
Oceania has a diverse political landscape, ranging from large, developed countries to small island nations, some of which face challenges related to climate change and rising sea levels.
