Characteristics[edit]
Oceania with its sovereign states and dependent territories within the subregions Australasia, Melanesia, Micronesia, and Polynesia
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.[better source needed] 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.
In most non-English-speaking countries, Oceania is treated as a continent in the sense that it is "one of the parts of the world", and Australia is only seen as an island nation. In other non-English-speaking countries Australia and Eurasia are thought of as continents, while Asia, Europe, and Oceania are regarded as "parts of the world". Various writers from English-speaking countries have also described Oceania as a continent over the years. Prior to the 1950s, before the popularization of the theory of plate tectonics, Antarctica, Australia, and Greenland were sometimes described as island continents, but none were usually taught as one of the world's continents in the English-speaking countries.. In his 1961 book The United States and the Southwest Pacific, American author Clinton Hartley Grattan commented that, by 1961, the term Oceania to describe Australia, New Zealand, and the Pacific Islands was considered somewhat outdated. Australia is a founding member of the Pacific Islands Forum in 1971, and at times has been interpreted as the largest Pacific island. Some geographers group the Australian tectonic plate with others in the Pacific to form a geological continent. National Geographic defines Oceania as a continent based on its connection to the Pacific Ocean rather than landmass. Others have labelled it as the "liquid continent". The Pacific Ocean itself has been labelled as a "continent of islands", and contains approximately 25,000, which is more than all the other major oceans combined. In a 1991 article, American archeologist Toni L. Carrell wrote, The vast size and distances within the Pacific Basin make it challenging to view it as a single geographical unit.
Oceania's subregions of Australasia, Melanesia, Micronesia, and Polynesia cover two major plates; the Australian Plate (also known as the Indo-Australian Plate) and the Pacific Plate, in addition to two minor plates; the Nazca Plate and the Philippine Sea Plate. The Australian Plate includes Australia, Fiji, New Caledonia, Papua New Guinea, Vanuatu, and parts of New Zealand. The Pacific Plate covers the Solomon Islands and parts of New Zealand, as well as Micronesia (excluding the westernmost islands near the Philippine Sea Plate) and Polynesia (excluding Easter Island). The Nazca Plate, which includes Easter Island, neighbours the South American Plate, and is still considered to be a separate tectonic plate, despite only containing a handful of islands.

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[edit]

Islands at the geographic extremes of Oceania are generally considered to be 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.
United Nations interpretation[edit]
Main article: United Nations geoscheme for Oceania
The United Nations (UN) has used its own geopolitical definition of Oceania since its foundation in 1947, which utilizes four of the five subregions from the 19th century: Australasia, Melanesia, Micronesia, and Polynesia. This definition consists of discrete political entities and so excludes the Bonin Islands, Hawaii, Clipperton Island, and the Juan Fernández Islands, along with Easter Island, which was annexed by Chile in 1888. It is used in statistical reports, by the International Olympic Committee, and by many atlases. The UN categorizes Oceania, and by extension the Pacific area, as one of the major continental divisions of the world, along with Africa, Asia, Europe, and the Americas. Their definition includes American Samoa, Australia and their external territories, the Cook Islands, Federated States of Micronesia, French Polynesia, Fiji, Guam, Kiribati, the Marshall Islands, Nauru, New Caledonia, New Zealand, Niue, the Northern Mariana Islands, Palau, Papua New Guinea, Pitcairn Islands, Samoa, the Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu, Wallis and Futuna, and the United States Minor Outlying Islands (Baker Island, Howland Island, Jarvis Island, Midway Atoll, Palmyra Atoll, and Wake Island). The original UN definition of Oceania from 1947 included these same countries and semi-independent territories, which were mostly still colonies at that point. Hawaii had not yet become a U.S. state in 1947, and as such was part of the original UN definition of Oceania. The island states of Indonesia, Japan, the Philippines, Singapore, and Taiwan, all located within the bounds of the Pacific or associated marginal seas, are excluded from the UN definition; already in 1947 Dutch New Guinea was counted as part of Asia. The states of Hong Kong and Malaysia, located in both mainland Asia and marginal seas of the Pacific, are also excluded, as are Brunei, East Timor, and Indonesian New Guinea/Western New Guinea. The CIA World Factbook also categorizes Oceania as one of the major continental divisions of the world, but the name "Australia and Oceania" is used. Their definition does not include all of Australia's external territories, but is otherwise the same as the UN's definition, and is also used for statistical purposes. The Pacific Islands Forum expanded during the early 2010s, and areas that were already included in the UN definition of Oceania, such as French Polynesia, gained membership.
Early interpretations[edit]
A German map of Oceania from 1884, showing the region to encompass Australia and all islands between Asia and Latin America
French writer Gustave d'Eichthal remarked in 1844 that Oceania's boundaries extended across the entire Pacific Ocean. Conrad Malte-Brun in 1824 defined Oceania as covering Australia, New Zealand, the islands of Polynesia (which then included all the Pacific islands) and the Malay Archipelago. Worcester described Oceania as a collection of numerous Pacific islands, categorizing it as one of the world's five major divisions. He also viewed Oceania as covering Australia, New Zealand, the Malay Archipelago and the islands of Melanesia, Micronesia, and Polynesia. In 1887, the Royal Asiatic Society of Great Britain and Ireland referred to Australia as the area's westernmost land, while in 1870, British Reverend Alexander Mackay identified the Bonin Islands as its northernmost point, and Macquarie Island as its southernmost point. The Bonin Islands at that time were a possession of Britain; Macquarie Island, to the south of Tasmania, is a subantarctic island in the Pacific. It was politically associated with Australia and Tasmania by 1870.
Alfred Russel Wallace believed in 1879 that Oceania extended to the Aleutian Islands, which are among the northernmost islands of the Pacific. The islands, now politically associated with Alaska, have historically had inhabitants that were related to Indigenous Americans, in addition to having non-tropical biogeography similar to that of Alaska and Siberia. Wallace insisted while the surface area of this wide definition was greater than that of Asia and Europe combined, the land area was only a little greater than that of Europe. American geographer Sophia S. Cornell claimed that the Aleutian Islands were not part of Oceania in 1857. She stated that Oceania was divided up into three groups; Australasia (which included Australia, New Zealand, and the Melanesian islands), Malesia (which included all present-day countries within the Malay Archipelago, not the modern country of Malaysia) and Polynesia (which included both the Polynesian and Micronesian islands in her definition). Aside from mainland Australia, areas that she identified as of high importance were Borneo, Hawaii, Indonesia's Java and Sumatra, New Guinea, New Zealand, the Philippines, French Polynesia's Society Islands, Tasmania, and Tonga.
American geographer Jesse Olney's 1845 book A Practical System of Modern Geography defined Oceania as consisting of the many islands of the Pacific located southeast of Asia. Olney divided up Oceania into three groups; Australasia (which included Australia, New Guinea, and New Zealand), Malesia and Polynesia (which included the combined islands of Melanesia, Micronesia, and Polynesia in his definition). Publication Missionary Review of the World claimed in 1895 that Oceania was divided into five groups: Australasia, Malesia, Melanesia, Micronesia, and Polynesia. It did not consider Hawaii to be part of Polynesia, due to its geographic isolation, commenting that Oceania also included, "isolated groups and islands, such as the Hawaiian and Galápagos." In 1876, French geographer Élisée Reclus described Australia's plant life as highly distinctive and noted that Hawaii and the Galápagos had significant numbers of unique, endemic plant species. Rand McNally & Company, an American publisher of maps and atlases, defined Oceania as including Australia and the Pacific islands while classifying the Malay Archipelago as part of Asia. British linguist Robert Needham Cust argued in 1887 that the Malay Archipelago should be excluded since it had participated in Asian civilization. Cust considered Oceania's four subregions to be Australasia, Melanesia, Micronesia and Polynesia. New Zealand was categorized by him as being in Polynesia; and the only country in his definition of Australasia was Australia. His definition of Polynesia included both Easter Island and Hawaii, which had not yet been annexed by either Chile or the United States.
The Journal of the Royal Statistical Society stated in 1892 that Australia was a large island within Oceania rather than a small continent. It additionally commented:
It is certainly not necessary to consider the Hawaiian Islands and Australia as being in the same part of the world; it is, however, permissible to unite in one group all the islands which are scattered over the great ocean. It should be remarked that if we take the Malay Archipelago away from Oceania, as do generally the German geographers, the insular world contained in the great ocean is cut in two, and the least populated of the five parts of the world is diminished to increase the number of inhabitants of the most densely populated continent.
Regarding Australia and the Pacific, Chambers's New Handy Volume American Encyclopædia observed in 1885 that, the term "Oceania" has been used interchangeably with "Australasia," though often excluding the Malay Archipelago, which some writers referred to as "Malesia". It added there was controversy over the exact limits of Oceania, saying that, the encyclopaedia mentioned the lack of agreement among geographers about the exact boundaries of Oceania. British physician and ethnologist James Cowles Prichard stated that the Aleutian and Kuril Islands, along with the coasts of Asia and America, marked the northern boundary of Oceania. However, Prichard argued that these islands were generally not considered part of Oceania because their inhabitants were not connected to the indigenous peoples of the more remote Pacific islands. He added that Hawaii was the most northerly area to be inhabited by races associated with Oceania.
The 1926 book Modern World History, 1776&ndash- 1926, by Alexander Clarence Flick, considered Oceania to include all islands in the Pacific, and associated the term with the Malay Archipelago, the islands of Melanesia, Micronesia, and Polynesia, the Aleutian Islands, Japan's Ryukyu Islands, Taiwan, and the Kuril Islands. He further included in his definition Sakhalin, an island which is geologically part of the Japanese Archipelago, but that has been administered by Russia since World War II. Hong Kong, partly located in another marginal sea of the Pacific (the South China Sea), was also included in his definition. Australia and New Zealand were grouped by Flick as Australasia and categorized as being in the same area of the world as the islands of Oceania. Flick described the demographic composition of Oceania, stating that the majority of the population consisted of "brown and yellow races," while whites were primarily "owners and rulers." Hutton Webster's 1919 book Medieval and Modern History also defined Oceania broadly, stating that it encompassed all islands in the Pacific. Webster broke Oceania up into two subdivisions: the continental group, which included Australia, the Japanese archipelago, the Malay Archipelago, and Taiwan, and the oceanic group, which included New Zealand and the islands of Melanesia, Micronesia, and Polynesia.
Charles Marion Tyler's 1885 book The Island World of the Pacific Ocean considered Oceania to ethnographically encompass Australia, New Zealand, the Malay Archipelago, and the islands of Melanesia, Micronesia, and Polynesia. However, Tyler included other Pacific islands in his book as well, such as the Aleutian Islands, the Bonin Islands, the Japanese archipelago, the Juan Fernández Islands, the Kuril Islands, the Ryukyu Islands, Taiwan, California's Channel Islands and Farallon Islands, Canada's Vancouver Island and Queen Charlotte Islands (now known as Haida Gwaii), Chile's Chiloé Island, Ecuador's Galápagos Islands, Mexico's Guadalupe Island, Revillagigedo Islands, San Benito Islands and Tres Marías Islands, and Peru's Chincha Islands. Islands in marginal seas of the Pacific were also covered in the book, including Alaska's Pribilof Islands and China's Hainan. Tyler additionally profiled the Anson Archipelago, which during the 19th century was a designation for a widely scattered group of purported islands in the Northwestern Pacific Ocean between Japan and Hawaii. The Anson archipelago included phantom islands such as Ganges Island and Los Jardines which were proven to not exist, as well as real islands such as Marcus Island and Wake Island. Tyler described Australia as "the leviathan of the island groups of the world". In his 1857 book A Treatise on Physical Geography, Francis B. Fogg defined Oceania, or "the Maritime World," as being divided into three major subregions: Australasia, Malesia, and Polynesia. Fogg defined Polynesia as covering the combined islands of Melanesia, Micronesia, and Polynesia, as well as the Ryukyu Islands. He listed additional significant islands in the Pacific beyond those in the standard subregions of Oceania. Scottish academic John Merry Ross in 1879 considered Polynesia to cover the entire South and Central Pacific area, not just islands ethnographically within Polynesia. He wrote in The Globe Encyclopedia of Universal Information that, in its broadest sense, Polynesia could include islands spanning from Sumatra to the Galápagos, along with Australia. Ross acknowledged that Oceania had historically been applied to this vast region but noted that, by his time, the Malay Archipelago was often excluded.
Historical and contemporary interpretations[edit]
In a 1972 article for the Music Educators Journal titled Musics of Oceania, author Raymond F. Kennedy wrote:
Many meanings have been given to the word Oceania. The most inclusive–but not always the most useful–embraces about 25,000 land areas between Asia and the Americas. A more popular and practical definition excludes Indonesia, East Malaysia (Borneo), the Philippines, Taiwan, Japan, and other islands closely related to the Asian mainland, as well as the Aleutians and the small island groups situated near the Americas. Thus, Oceania most commonly refers to the land areas of the South and Central Pacific.
Kennedy defined Oceania as including Australasia, Melanesia, Micronesia, and Polynesia. The U.S. Government Publishing Office's Area Handbook for Oceania from 1971 states that Australia and New Zealand are the principal large sovereignties of the area. It further states:
In its broadest definition, Oceania embraces all islands and island groups of the Pacific Ocean that lie between Asia and the two American continents. In popular usage, however, the designation has a more restricted application. The islands of the North Pacific, such as the Aleutians and the Kuriles, are usually excluded. In addition, the series of sovereign island nations fringing Asia (Japan, Taiwan, the Philippines, East Malaysia, the Republic of Indonesia) is not ordinarily considered to be part of the area.
In 1948, American military journal Armed Forces Talk broke the islands of the Pacific up into five major subdivisions: Indonesia, Melanesia, Micronesia, Polynesia, and the non-tropical Islands. The Indonesian subdivision consisted of the islands of the Malay Archipelago, while the non-tropical islands were categorized as being North Pacific islands, such as Alaska's Kodiak archipelago, the Aleutian Islands, Japan, the Kuril Islands, and Sakhalin. Japan's Bonin and Ryukyu Islands are also considered to be subtropical islands, with the main Japanese archipelago being non-tropical. The journal associated the term Oceania with the Melanesian, Micronesian, and Polynesian subdivisions, but not with the Indonesian or non-tropical subdivisions. The Pacific Islands Handbook (1945), by Robert William Robson, stated that, "Pacific Islands generally are regarded as Pacific islands lying within the tropics. There are a considerable number of Pacific Islands outside the tropics. Most of them have little economic or political importance." He noted the political significance of the Aleutian Islands, which were invaded by the Japanese military in World War II, and categorized New Zealand's Antipodes Islands, Auckland Islands, Bounty Islands, Campbell Islands, Chatham Island and Kermadec Islands as being non-tropical islands of the South Pacific, along with Australia's Lord Howe Island and Norfolk Island. The Kermadec Islands, Lord Howe Island, and Norfolk Island are also considered to be subtropical islands. Other non-tropical areas below the equator, such as Chiloé Island, Macquarie Island, Tasmania, and the southern portions of mainland Australia and New Zealand, were not included in this category.
According to the 1998 book Encyclopedia of Earth and Physical Sciences, Oceania refers to Australasia, Melanesia, Micronesia, Polynesia, and more than 10,000 islands scattered across the Pacific Ocean. It notes that, "the term [has] also come under scrutiny by many geographers. Some experts insist that Oceania encompasses even the cold Aleutian Islands and the islands of Japan. Disagreement also exists over whether or not Indonesia, the Philippines, and Taiwan should be included in Oceania." The Japanese Archipelago, the Malay Archipelago and Taiwan and other islands near China are often deemed as a geological extension of Asia, since they do not have oceanic geology, instead being detached fragments of the Eurasian continent that were once physiographically connected. Certain Japanese islands off the main archipelago are not geologically associated with Asia. The book The World and Its Peoples: Australia, New Zealand, Oceania (1966) asserts that, "Japan, Taiwan, the Aleutian Islands, Indonesia, the Philippines and Malaysia [and] the Pacific archipelagos bordering upon the Far East Asian mainland are excluded from Oceania", and that "all the islands lying between Australia and the Americas, including Australia, are part of Oceania." Furthermore, the book adds that Hawaii is still within Oceania, despite being politically integrated into the U.S., and that the Pacific Ocean "gives unity to the whole" since "all these varied lands emerge from or border upon the Pacific."
The 1876 book The Countries of the World, by British scientist and explorer Robert Brown, labelled the Malay Archipelago as Northwestern Oceania, but Brown still noted that these islands belonged more to the Asian continent. They are now often referred to as Maritime Southeast Asia, with Indonesia, Malaysia, the Philippines, and Singapore being founding members of the ASEAN regional organization for Southeast Asia in 1967 (Brunei and East Timor did not exist as independent nations at that point). Brown also categorized Japan and Taiwan as being in the same part of the world as the islands of Oceania, and excluded them from The Countries of the World: Volume 5, which covered mainland Asia and Hong Kong. However, Brown did not explicitly associate Japan or Taiwan with the term Oceania. He divided Oceania into two subregions: Eastern Oceania, which included the islands of Melanesia, Micronesia, and Polynesia, and Southwestern Oceania, which included Australia and New Zealand. The Galápagos Islands, the Juan Fernández Islands, and the Revillagigedo Islands were identified as the easternmost areas of Oceania in the book. Brown wrote, "they lie nearest the American continent of all oceanic islands, and though rarely associated with Polynesia, and never appearing to have been inhabited by any aboriginal races, are, in many ways, remarkable and interesting." Brown went on to add, "the small islands lying off the continent, like the Queen Charlotte's in the North Pacific, the Farallones off California, and the Chinchas off Peru are—to all intents and purposes, only detached bits of the adjoining shores. But in the case of the Galápagos, at least, this is different." The Juan Fernández Islands and the neighbouring Desventuradas Islands are today seen as the easternmost extension of the Indo-West Pacific biogeographic region. The islands lie on the Nazca Plate with Easter Island and the Galápagos Islands, and have a significant south-central Pacific component to their marine fauna. According to scientific journal PLOS One, the Humboldt Current helps create a biogeographic barrier between the marine fauna of these islands and South America. Chile's government have occasionally considered them to be within Oceania along with Easter Island. Chile's government also categorizes Easter Island, the Desventuradas Islands, and the Juan Fernández Islands as being part of a region titled Insular Chile. They further include in this region Salas y Gómez, a small uninhabited island to the east of Easter Island. PLOS One describes Insular Chile as having "cultural and ecological connections to the broader insular Pacific."
A map of member states for the Pacific Islands Forum, the member states are depicted in blue. The PIF is a governing organization for the Pacific, and all of its members are seen as being politically within Oceania. Territories ethnographically associated with Oceania, but not politically associated with Oceania, such as Easter Island, Hawaii, and Western New Guinea, have considered gaining representation in the PIF. The Pacific island nations of Indonesia, Japan, Malaysia, the Philippines, Singapore, and Taiwan are dialogue partners, but none have full membership. East Timor, located in the marginal seas of the Pacific and Indian Oceans, also has observer status.

In her 1997 book Australia and Oceania, Australian historian Kate Darian-Smith defined the area as covering Australia, New Zealand, and the islands of Melanesia, Micronesia, and Polynesia. She excluded Hawaii from her definition, but not Easter Island. The International Union for Conservation of Nature stated in a 1986 report that they include Easter Island in their definition of Oceania "based on its Polynesian and biogeographic affinities even though it is politically apart", further noting that other oceanic islands administered by Latin American countries had been included in definitions of Oceania. In 1987, The Journal of Australasian Cave Research described Oceania as being "the region from Irian Jaya (Western New Guinea, a province of New Guinea) in the west to Galápagos Islands (Equador) and Easter Island (Chile) in the east." In a 1980 report on venereal diseases in the South Pacific, the British Journal of Venereal Diseases categorized the Desventuradas Islands, Easter Island, the Galápagos Islands and the Juan Fernández Islands as being in an eastern region of the South Pacific, along with areas such as Pitcairn Islands and French Polynesia, but noted that the Galápagos Islands were not a member of the South Pacific Commission, like other islands in the South Pacific. The South Pacific Commission is a developmental organization formed in 1947 and is currently known as the Pacific Community; its members include Australia and other Pacific Islands Forum members. In a 1947 article on the formation of the South Pacific Commission for the Pacific Affairs journal, author Roy E. James stated the organization's scope encompassed all non-self-governing islands below the equator to the east of Papua New Guinea (which itself was included in the scope and then known as Dutch New Guinea). Easter Island and the Galápagos Islands were defined by James as falling within the organization's geographical parameters. The 2007 book Asia in the Pacific Islands: Replacing the West, by New Zealand Pacific scholar Ron Crocombe, defined the term "Pacific Islands" as being islands in the South Pacific Commission, and stated that such a definition "does not include Galápagos and other [oceanic] islands off the Pacific coast of the Americas; these were uninhabited when Europeans arrived, then integrated with a South American country and have almost no contact with other Pacific Islands." He adds, "Easter Island still participates in some Pacific Island affairs because its people are Polynesian."
Thomas Sebeok's two volume 1971 book Linguistics in Oceania defines Easter Island, the Galápagos Islands, the Juan Fernández Islands, Costa Rica's Cocos Island and Colombia's Malpelo Island (all oceanic) as making up a Spanish language segment of Oceania. Cocos Island and Malpelo Island are the only landmasses located on the Cocos Plate, which is to the north of the Nazca Plate. The book observed that a native Polynesian language was still understood on Easter Island, unlike on the other islands, which were uninhabited when discovered by Europeans and were mostly being used as prisons for convicts. Additionally, the book includes Taiwan and the entire Malay Archipelago as part of Oceania. While not oceanic in nature, Taiwan and Malay Archipelago countries like Indonesia and the Philippines share Austronesian ethnolinguistic origins with Melanesia, Micronesia and Polynesia, hence their inclusion in the book. Hainan, which neighbours Taiwan, also has Austronesian ethnolinguistic origins, although it was not included in the book. The book defined Oceania's major subregions as being Australia, Indonesia (which included all areas associated with the Malay Archipelago), Melanesia, Micronesia, and Polynesia. In 2010, Australian historian Bronwen Douglas claimed in The Journal of Pacific History that "a strong case could be made for extending Oceania to at least Taiwan, the homeland of the Austronesian language family whose speakers colonized significant parts of the region about 6,000 years ago." For political reasons, Taiwan was a member of the Oceania Football Confederation during the 1970s and 1980s, rather than the Asian Football Confederation.
Ian Todd's 1974 book Island Realm: A Pacific Panorama also defines oceanic Latin American islands as making up a Spanish language segment of Oceania, and includes the Desventuradas Islands, Easter Island, the Galápagos Islands, Guadalupe Island, the Juan Fernández Islands, the Revillagigedo Islands, and Salas y Gómez. Cocos Island and Malpelo Island were not explicitly referenced in the book, despite being areas that would fall within this range. All other islands associated with Latin American countries were excluded, as they are continental in nature, unlike Guadalupe Island and the Revillagigedo Islands (both situated on the Pacific Plate) and the oceanic islands situated on the Cocos Plate and Nazca Plate. Todd defined the oceanic Bonin Islands as making up a Japanese language segment of Oceania, and excluded the main Japanese archipelago. Todd further included the Aleutian Islands in his definition of Oceania. The island chain borders both the Pacific Plate and the North American Plate, and is geologically a partially submerged volcanic extension of the Aleutian Range on the Alaskan mainland. He did not include the volcanic Kuril Islands and Ryukyu Islands, which similarly border both the Eurasian Plate and the Pacific Plate, nor did he include the neighbouring Kodiak archipelago in the North Pacific Ocean, which is firmly situated on the North American Plate. The Stockholm Journal of East Asian Studies stated in 1996 that Oceania was defined as Australia and an ensemble of various Pacific Islands, "particularly those in the central and south Pacific [but] never those in the extreme north, for example the Aleutian chain." In the Pacific Ocean Handbook (1945), author Eliot Grinnell Mears claimed, "it is customary to exclude the Aleutians of the North Pacific, the American coastal islands and the Netherlands East Indies", and that he included Australia and New Zealand in Oceania for "scientific reasons; Australia's fauna is largely continental in character, New Zealand's are clearly insular; and neither Commonwealth realm has close ties with Asia." In his 2002 book Oceania: An Introduction to the Cultures and Identities of Pacific Islanders, Andrew Strathern excluded Okinawa and the rest of the Ryukyu Islands from his definition of Oceania, but noted that the islands and their indigenous inhabitants "show many parallels with Pacific island societies."
In the 2006 book Extinction and Biogeography of Tropical Pacific Birds, American paleontologist David Steadman wrote, "no place on earth is as perplexing as the 25,000 islands that make Oceania." Steadman viewed Oceania as encompassing Melanesia, Micronesia, and Polynesia (including Easter Island and Hawaii). He excluded from his definition the larger islands of New Guinea and New Zealand, and argued that Cocos Island, the Galápagos Islands, the Revillagigedo Islands, and other oceanic islands near the Americas were not part of Oceania, due to their biogeographical affinities with that area and lack of prehistoric indigenous populations. In his 2018 book Regionalism in South Pacific, Chinese author Yu Changsen wrote that some "stress a narrow vision of the Pacific as those Pacific Islands excluding Australia and even sometimes New Zealand", adding that the term Oceania "promotes a broader concept that has room for Australia and New Zealand."
American marine geologist Anthony A. P. Koppers wrote in the 2009 book Encyclopedia of Islands that, "as a whole, the islands of the Pacific Region are referred to as Oceania, the tenth continent on earth. Inherent to their remoteness and because of the wide variety of island types, the Pacific Islands have developed unique social, biological, and geological characteristics." Koppers considered Oceania to encompass the entire 25,000 islands of the Pacific Ocean. In this book, he included the Aleutian Islands, the Galápagos Islands, the Japanese archipelago, the Kuril Islands and continental islands off the coast of the Americas such as the Channel Islands, the Farallon Islands and Vancouver Island; all of these islands lie in or close to the Pacific Ring of Fire, as is the case with New Guinea and New Zealand, which were also included. In the 2013 book The Environments of the Poor in Southeast Asia, East Asia and the Pacific, Paul Bullen critiqued the definition of Oceania in Encyclopedia of Islands, and wrote that since Koppers included areas such as Vancouver Island, it is "not clear what the referents of 'Pacific Region', 'Oceania' or 'Pacific Islands' are." Bullen added, "Asia, Europe, and the Maritime Continent are not literal geographic continents. The 'Asia–Pacific region' would comprise two quasi-continents. 'The Pacific' would not refer to the Pacific Ocean and everything in it, e.g., the Philippines." The Concise Oxford Dictionary of World Place Names (2017), by John Everett-Heath, states that Oceania is "a collective name for more than 10,000 islands in the Pacific Ocean" and that "it is generally accepted that Indonesia, Japan, the Philippines, Taiwan, and the islands north of Japan (the Kurils and Aleutians) are excluded." In his 1993 book A New Oceania: Rediscovering Our Sea of Islands, New Guinea-born Fijian scholar Epeli Hauʻofa wrote that, "Pacific Ocean islands from Japan, through the Philippines and Indonesia, which are adjacent to the Asian mainland, do not have oceanic cultures, and are therefore not part of Oceania."
The Oxford Handbook of Prehistoric Oceania (2018) defined Oceania as only covering Austronesian-speaking islands in Melanesia, Micronesia, and Polynesia, with this definition including New Guinea and New Zealand. Other Austronesian areas, such as Indonesia and the Philippines, were not included due to their closer cultural proximity to mainland Asia. Australia was also not included, as it was settled several thousand of years before the arrival of Austronesian-speaking peoples in Melanesia, Micronesia, and Polynesia. The book stated, "this definition of Oceania might seem too restrictive: Why not include Australia, for example, or even too broad, for what does Highland New Guinea have to do with Hawaiʻi?", further noting that, "a few other islands in the Pacific such as those of Japan or the Channel Islands off the southern California coast are not typically considered Oceania as the indigenous populations of these places do not share a common ancestry with Oceanic groups, except for a time far before humans sailed Pacific waters." It has been theorized that the indigenous Jōmon people of the Japanese archipelago are related to Austronesians, along with the indigenous inhabitants of the Ryukyu Islands. Some also theorize that Indigenous Australians are related to the Ainu people, who are the original inhabitants of Japan's Hokkaido, the Kuril Islands and the southern part of Sakhalin. In their 2019 book Women and Violence: Global Lives in Focus, Kathleen Nadeau and Sangita Rayamajhi wrote:
The Philippines, Malaysia, Brunei, and most of Indonesia are not usually considered to be part of the region of Oceania as it is understood today. These regions are usually considered to be part of Maritime Southeast Asia. These regions, as well as the large East Asian islands of Taiwan, Hainan, and the Japanese archipelago, have varying degrees of cultural connections.
In Reptiles and Amphibians of the Pacific Islands: A Comprehensive Guide (2013), George R. Zug claimed that "a standard definition of Oceania includes Australia, Papua New Guinea, the Solomon Islands, New Caledonia, and New Zealand, and the oceanic islands of Polynesia, Micronesia, and Melanesia." He went on to write that his preferred definition of Oceania emphasizes islands with oceanic geology, stating that oceanic islands are, "islands with no past connections to a continental landmass" and that, "these boundaries encompass the Hawaiian and Bonin Islands in the north and Easter Island in the south, and the Palau Islands in the west to the Galápagos Islands in the east." Australia, New Guinea, New Zealand and New Caledonia (which is geologically associated with New Zealand) were all excluded, as these areas are descendants of the ancient Pangaea supercontinent, along with landmasses such as the Americas and Afro-Eurasia. Volcanic islands which are geologically associated with continental landmasses, such as the Aleutian Islands, Japan's Izu Islands, the Kuril Islands, the Ryukyu Islands, and most of the Solomon Islands, were also excluded from his definition. Unlike the United Nations, the World Factbook defines the still-uninhabited Clipperton Island as being a discrete political entity, and they categorize it as part of North America, presumably due to its relative proximity (situated 1,200 kilometres off Mexico on the Pacific Plate). Clipperton is not politically associated with the Americas, as is the case with other oceanic islands near the Americas, having had almost no interaction with the continent throughout its history. From the early 20th century to 2007, the island was administratively part of French Polynesia, which itself was known as French Oceania up until 1957. In terms of marine fauna, Clipperton shares similarities with areas of the Pacific which are much farther removed from the Americas. Scottish author Robert Hope Moncrieff considered Clipperton to be the easternmost point of Oceania in 1907, while Ian Todd also included it in his definition of Oceania in Island Realm: A Pacific Panorama.
Other uninhabited Pacific Ocean landmasses have been explicitly associated with Oceania, including the highly remote Baker Island and Wake Island (now administered by the U.S. military). This is due to their location in the centre of the Pacific, their biogeography and their oceanic geology. Less isolated oceanic islands that were once uninhabited, such as the Bonin Islands, the Galápagos Islands and the Juan Fernández Islands, have since been sparsely populated by citizens of their political administrators. Archaeological evidence suggests that Micronesians may have lived on the Bonin Islands c. 2,000 years ago, but they were uninhabited at the time of European discovery in the 16th century.
Boundaries between subregions[edit]
Depending on the definition, New Zealand could be part of Polynesia, or part of Australasia with Australia. New Zealand was originally settled by the Polynesian Māori, and has long maintained a political influence over the subregion. Through immigration and high Māori birth rates, New Zealand has attained the largest population of Polynesians in the world, while Australia has the third largest Polynesian population (consisting entirely of immigrants). Modern-day Indigenous Australians are loosely related to Melanesians, and Australia maintains political influence over Melanesia, which is mostly located on the same tectonic plate. Despite this, Australia is rarely seen as a part of the subregion. As with Australia and New Zealand, Melanesia's New Caledonia has a significant non-indigenous European population, numbering around 71,000. Conversely, New Caledonia has still had a similar history to the rest of Melanesia, and their French-speaking Europeans make up only 27% of the total population. As such, it is not also culturally considered a part of the predominantly English-speaking Australasia. Some cultural and political definitions of Australasia include most or all of Melanesia, due to its geographical proximity to Australia and New Zealand, but these are rare. Australia, New Zealand and the islands of Melanesia are more commonly grouped together as part of the Australasian biogeographical realm. Papua New Guinea is geographically the closest country to Australia, and is often geologically associated with Australia as it was once physiologically connected. Australia's Indian Ocean external territories of Christmas Island and Cocos (Keeling) Islands are situated within the bounds of the Australian Plate and have been geographically associated with Southeast Asia, due to their proximity to western Indonesia. Both were uninhabited when discovered by Europeans during the 17th century. Approximately half of the population on these islands are European Australian mainlanders (with smaller numbers being European New Zealanders), while the other half are immigrants from China or the nearby Malay Archipelago. Australia's Indian Ocean external territory Heard Island and McDonald Islands lie on the Antarctic Plate and are also thought of as being in Antarctica or no region at all, due to their extreme geographical isolation. The World Factbook define Heard Island and McDonald Islands as part of Antarctica, while placing Christmas Island and Cocos (Keeling) Islands as the westernmost extent of Oceania.
Norfolk Island, an external territory of Australia, was inhabited in prehistoric times by either Melanesians or Polynesians, and is geographically adjacent to the islands of Melanesia. The current inhabitants are mostly European Australians, and the UN categorizes it as being in the Australasia subregion. The 1982 edition of the South Pacific Handbook, by David Stanley, groups Australia, New Zealand, Norfolk Island, and Hawaiʻi together under an "Anglonesia" category. This is despite the geographical distance separating these areas from Hawaiʻi, which technically lies in the North Pacific. The 1985 edition of the South Pacific Handbook also groups the Galápagos Islands as being in Polynesia, while noting that they are not culturally a part of the subregion. The islands are typically grouped with others in the southeastern Pacific that were never inhabited by Polynesians.
The Bonin Islands are in the same biogeographical realm as the geographically adjacent Micronesia, and are often grouped in with the subregion because of this.
