Oceania is a geographical region including Australasia, Melanesia, Micronesia, and Polynesia. Oceania is also described as a continent, with mainland Australia regarded as its continental landmass. Spanning the Eastern and Western hemispheres, at the centre of the water hemisphere, Oceania is estimated to have a land area of about 9,000,000 square kilometres (3,500,000 sq mi) and a population of around 46.3 million as of 2024, when including Australia but excluding the Malay Archipelago. When compared against other continental land areas, Oceania is the smallest and the second-least populated after Antarctica. It is home to Earth’s third-largest remaining area of tropical rainforest, which covers much of the island of New Guinea. Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia, French Polynesia, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much less developed economies of Kiribati, Papua New Guinea, Tuvalu, Vanuatu, and Western New Guinea. The largest and most populous country in Oceania is Australia, and the largest city is Sydney. Puncak Jaya in Indonesia is the highest peak in Oceania at 4,884 m (16,024 ft). The first settlers of Australia, New Guinea, and the large islands just to the east arrived more than 60,000 years ago. Oceania was first explored by Europeans from the 16th century onward. Portuguese explorers, between 1512 and 1526, reached the Tanimbar Islands, some of the Caroline Islands, and west New Guinea. Spanish and Dutch explorers followed, then British and French. On his first voyage in the 18th century, James Cook, who later arrived at the highly developed Hawaiian Islands, went to Tahiti and followed the east coast of Australia for the first time. The arrival of European settlers in subsequent centuries resulted in a significant alteration in the social and political landscape of Oceania. The Pacific theatre saw major action during the First and Second World Wars. The rock art of Aboriginal Australians is the longest continuously practiced artistic tradition in the world. Most Oceanian countries are parliamentary democracies, with tourism serving as a large source of income for the Pacific island nations.
Etymology Oceania is from the French océanie coming from greek Okeanòs, Ωκεανός, ocean. It was coined in 1812 by geographer Conrad Malte-Brun.
Definition
Characteristics
Definitions of Oceania vary. The broadest definition encompasses the islands between mainland Asia and the Americas. The island nation of Australia is the only piece of land in the area which is large enough to typically be considered a continent. The culture of the people who lived on these islands was often distinct from that of Asia and pre-Columbian America. Before Europeans arrived in the area, the sea shielded Australia and south central Pacific islands from cultural influences that spread through large continental landmasses and adjacent islands. The islands of the Malay Archipelago, north of Australia, mainly lie on the continental shelf of Asia, and their inhabitants had more exposure to mainland Asian culture as a result of this closer proximity.
The geographer Conrad Malte-Brun coined the French expression Terres océaniques ('Oceanic lands') c. 1804. In 1814 another French cartographer, Adrien-Hubert Brué, coined from this expression the shorter Océanie, which derives from the Latin word oceanus, and this from the Greek word ὠκεανός (ōkeanós), 'ocean'. The term Oceania is used because, unlike the other continental groupings, it is the ocean that links the parts of the region together. John Eperjesi's 2005 book The Imperialist Imaginary says that Since the mid-19th century, Western cartographers have used the term Oceania to organize and classify the Pacific region.
In the 19th century, many geographers divided Oceania into mostly racially based subdivisions: Australasia, Malesia (encompassing the Malay Archipelago), Melanesia, Micronesia, and Polynesia. The 2011 book Maritime Adaptations of the Pacific, by Richard W. Casteel and Jean-Claude Passeron, states that Oceania has traditionally been considered a continent in anthropological studies, similar to Africa, Asia, and the Americas. Bartholomew described Oceania as one of six major world divisions, including Australia and Pacific islands. American author Samuel Griswold Goodrich wrote in his 1854 book History of All Nations that, some 19th-century geographers classified the Pacific islands as a third continent called Oceania, alongside the New and Old Worlds. In this book, the other two continents were categorized as being the New World (the Americas) and the Old World (Afro-Eurasia). In his 1879 book Australasia, British naturalist Alfred Russel Wallace commented that, geographers commonly used Oceania to refer to the Pacific islands, with Australia as its central landmass. He did not explicitly label Oceania a continent in the book, but did note that it was one of the six major divisions of the world. The Oxford Handbook of World History (2011) describes the Oceania is often treated as a secondary topic in world history, appearing at the end of global narratives as a marginal region.
The new terms Near Oceania and Remote Oceania were proposed in 1973 by anthropologists Roger Green and Andrew Pawley. By their definition, Near Oceania consists of New Guinea, the Bismarck Archipelago, and the Solomon Islands, except the Santa Cruz Islands. They are designed to dispel the outdated categories of Melanesia, Micronesia, and Polynesia; many scholars now replace those categories with Green's terms since the early 1990s, but the old categories are still used in science, popular culture and general usage.
Boundaries
Islands that are generally considered to be at the geographic extremes of Oceania are: the Bonin Islands, a politically integral part of Japan; Hawaii, a state of the United States; Clipperton Island, a possession of France; Rapa Nui (Easter Island), belonging to Chile; and Macquarie Island, belonging to Australia.
