Australia and Oceania
Oceania spans Australia, New Zealand and thousands of Pacific islands.
About this topic
Oceania includes Australia, New Zealand, Papua New Guinea and thousands of Pacific islands, grouped as Melanesia, Micronesia and Polynesia. Australia is mostly arid, with the Outback, Great Barrier Reef and unique wildlife (kangaroos, koalas) due to long isolation, and the population is concentrated along the coast, particularly in the south-east where rainfall is more reliable. New Zealand has volcanic and mountainous landscapes.
Because Australia separated from other landmasses millions of years ago, most of its mammals are marsupials that carry young in pouches, and many species exist nowhere else. The Great Barrier Reef, the largest coral reef system, is visible from space but is threatened by warming seas that cause coral bleaching. Droughts and bushfires are frequent hazards.
Indigenous peoples (Aboriginal Australians, Maori) have lived there for thousands of years. Pacific islands, low-lying atolls in particular, face threats from rising sea levels and cyclones, and some nations such as Tuvalu and Kiribati worry about long-term survival. The economy relies on minerals, agriculture, tourism and services. A common mistake is to think Oceania is only Australia and New Zealand; most of its countries are small island states spread across a huge area of ocean.
