Oceania (UK: /ˌoʊsiˈɑːniə, ˌoʊʃi-, -ˈeɪn-/ OH-s(h)ee-AH-nee-ə, -⁠AY-, US: /ˌoʊʃiˈæniə, -ˈɑːn-/ OH-shee-A(H)N-ee-ə) is a geographical region including Australasia, Melanesia, Micronesia, and Polynesia. Outside of the English-speaking world, Oceania is generally considered a continent, while Mainland Australia is 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. Oceania is the smallest continent in land area and the second-least populated after Antarctica.

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).

New Zealand is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island (Te Ika-a-Māui) and the South Island (Te Waipounamu)—and over 600 smaller islands. It is the sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps (Kā Tiritiri o te Moana), owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.

The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1769 the British explorer Captain James Cook became the first European to set foot on and map New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs signed the Treaty of Waitangi, which paved the way for Britain's declaration of sovereignty later that year and the establishment of the Crown Colony of New Zealand in 1841. Subsequently, a series of conflicts between the colonial government and Māori tribes resulted in the alienation and confiscation of large amounts of Māori land. New Zealand became a dominion in 1907; it gained full statutory independence in 1947, retaining the monarch as head of state. Today, the majority of New Zealand's population of around 5.3 million is of European descent; the indigenous Māori are the largest minority, followed by Asians and Pasifika. Reflecting this, New Zealand's culture mainly derives from Māori and early British settlers but has recently broadened from increased immigration. The official languages are English, Māori, and New Zealand Sign Language, with the local dialect of English being dominant.

Zealandia (pronounced /ziːˈlændiə/), also known as Te Riu-a-Māui (Māori) or Tasmantis (from Tasman Sea), is an almost entirely submerged mass of continental crust in Oceania that subsided after breaking away from Gondwana 83–79 million years ago. It has been described variously as a submerged continent, continental fragment, and microcontinent. The name and concept for Zealandia was proposed by Bruce Luyendyk in 1995, and satellite imagery shows it to be almost the size of Australia. A 2021 study suggests Zealandia is over a billion years old, about twice as old as geologists previously thought.

By approximately 23 million years ago, the landmass may have been completely submerged. Today, most of the landmass (94%) remains submerged beneath the Pacific Ocean. New Zealand is the largest part of Zealandia that is above sea level, followed by New Caledonia.

Vanuatu (English: /ˌvɑːnuˈɑːtuː/ VAH-noo-AH-too or /vænˈwɑːtuː/ van-WAH-too; Bislama and French pronunciation [vanuatu]), officially the Republic of Vanuatu (French: République de Vanuatu; Bislama: Ripablik blong Vanuatu), is an island country in Melanesia located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is 1,750 km (1,090 mi) east of northern Australia, 540 km (340 mi) northeast of New Caledonia, east of New Guinea, southeast of Solomon Islands, and west of Fiji.

Vanuatu was first inhabited by Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Fernandes de Queirós, who arrived on the largest island, Espíritu Santo, in 1606. Queirós claimed the archipelago for Spain, as part of the colonial Spanish East Indies and named it La Austrialia del Espíritu Santo.

Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. In 2025, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia. Joseph Dalton Hooker (1817 – 1911) was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent.

Based on the similarities in their flora, botanist Ronald D'Oyley Good identified a separate Antarctic Floristic Kingdom that included southern South America, New Zealand, and some southern island groups. In addition, Australia was determined to be its own floristic kingdom because of the influx of tropical Eurasian flora that had mostly supplanted the Antarctic flora and included New Guinea and New Caledonia in the Paleotropical floristic kingdom.

Olea paniculata, commonly known as the native olive, is a plant of the genus Olea and a relative of the olive. It grows natively in Pakistan and southwestern China (Yunnan) through tropical Asia to Australia (Queensland and New South Wales) and the Pacific islands of New Caledonia, Vanuatu and Lord Howe Island.

Overseas France (French: France d'outre-mer, also France ultramarine) consists of 13 French territories outside Europe, mostly the remnants of the French colonial empire that remained a part of the French state under various statuses after decolonisation.

"Overseas France" is a collective name; while used in everyday life in France, it is not an administrative designation in its own right. Instead, the five overseas regions have exactly the same administrative status as the thirteen metropolitan regions; the five overseas collectivities are semi-autonomous; and New Caledonia is an autonomous territory. Overseas France includes island territories in the Atlantic, Pacific and Indian oceans, French Guiana on the South American continent, and several peri-Antarctic islands as well as a claim in Antarctica. Excluding the district of Adélie Land, where French sovereignty is effective de jure by French law, but where the French exclusive claim on this part of Antarctica is frozen by the Antarctic Treaty (signed in 1959), overseas France covers a land area of 120,396 km (46,485 sq mi) and accounts for 18.0% of the French Republic's land territory. Its exclusive economic zone (EEZ) of 9,825,538 km (3,793,661 sq mi) accounts for 96.7% of the EEZ of the French Republic.

Solomon Islands, also known simply as the Solomons, is an island country consisting of six major islands and over 1,000 smaller islands in Melanesia, Oceania, to the north-east of the country of Australia. It is directly adjacent to the Autonomous Region of Bougainville to the west, Australia to the south-west, New Caledonia and Vanuatu to the south-east, Fiji, Tuvalu, and Wallis and Futuna to the east, and the Federated States of Micronesia and Nauru to the north. It has a total area of 28,896 square kilometres (11,157 sq mi), and a population of 734,887 according to the official estimates for mid-2023. Its capital and largest city, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands archipelago, which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands.

The islands have been settled since at least some time between 30,000 and 28,800 BC, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called "the Solomons" by those who later received word of his voyage and mapped his discovery. Mendaña returned decades later, in 1595, and another Spanish expedition, led by Portuguese navigator Pedro Fernandes de Queirós, visited the Solomons in 1606.

Tonga, officially the Kingdom of Tonga, is an island country in Polynesia, part of Oceania. The country has 171 islands, of which 45 are inhabited. Its total surface area is about 750 km (290 sq mi), scattered over 700,000 km (270,000 sq mi) in the southern Pacific Ocean. As of 2021, according to Johnson's Tribune, Tonga has a population of 104,494, 70% of whom reside on the main island, Tongatapu. The country stretches approximately 800 km (500 mi; 430 nmi) north-south. It is surrounded by Fiji and Wallis and Futuna (France) to the northwest, Samoa to the northeast, New Caledonia (France) and Vanuatu to the west, Niue (the nearest foreign territory) to the east and Kermadec (New Zealand) to the southwest. Tonga is about 1,800 km (1,100 mi; 970 nmi) from New Zealand's North Island.

Tonga was first inhabited roughly 2,500 years ago by people who were a part of the Lapita culture, Polynesian settlers who gradually evolved a distinct and strong ethnic identity, language, and culture as the Tongan people. They quickly established a powerful footing across the South Pacific, and this period of Tongan expansionism and colonization is known as the Tuʻi Tonga Empire. From the rule of the first Tongan king, ʻAhoʻeitu, Tonga grew into a regional power. It was a thalassocracy that conquered and controlled unprecedented swathes of the Pacific, from parts of the Solomon Islands and the whole of New Caledonia and Fiji in the west to Samoa and Niue and even as far as parts of modern-day French Polynesia in the east. Tuʻi Tonga became renowned for its economic, ethnic, and cultural influence over the Pacific, which remained strong even after the Samoan revolution of the 13th century and Europeans' discovery of the islands in 1616.

The Pacific Community (PC), formerly the South Pacific Commission (SPC), is an international development organisation governed by 27 members, including 22 Pacific island countries and territories around the Pacific Ocean. The organisation's headquarters are in Nouméa, New Caledonia, and it has regional offices in Suva, Pohnpei, and Port Vila, as well as field staff in other locations in the Pacific. Its working languages are English and French. It primarily provides technical and scientific advice, and acts as a conduit for funding of development projects from donor nations. Unlike the slightly smaller Pacific Islands Forum, PaciCom is not a trade bloc, and does not deal with military or security issues.

PaciCom's regional development issues include climate change, disaster risk management, fisheries, food security, education, gender equality, human rights, non-communicable diseases, agriculture, forestry and land use, water resources, and youth employment.

Araucaria ( /ærɔːˈkɛəriə/; original pronunciation: [a.ɾawˈka. ɾja]) is a genus of evergreen coniferous trees in the family Araucariaceae. While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed. There are 20 extant species in New Caledonia (where 14 species are endemic, see New Caledonian Araucaria), eastern Australia (including Norfolk Island), New Guinea, Argentina, Brazil, Chile and Uruguay.

The genus is familiar to many people as the genus of the distinctive Chilean pine or monkey-puzzle tree (Araucaria araucana). No distinct vernacular name exists for the genus. Many are called "pine", although they are only distantly related to true pines, in the genus Pinus.

Island Melanesia is a subregion of Melanesia in Oceania.

It is located east of New Guinea island, from the Bismarck Archipelago to New Caledonia.

Pacific Islanders, Pasifika, Pasefika, Pacificans, or rarely Pacificers are the peoples of the Pacific Islands. As an ethnic/racial term, it is used to describe the original peoples—inhabitants and diasporas—of any of the three major subregions of Oceania (Melanesia, Micronesia, and Polynesia) or any other island located in the Pacific Ocean.

Melanesians include the Fijians (Fiji), Kanaks (New Caledonia), Ni-Vanuatu (Vanuatu), Papua New Guineans (Papua New Guinea), Solomon Islanders (Solomon Islands), West Papuans (Indonesia's West Papua) and Moluccans (Indonesia's Maluku Islands).

South Sea Islanders, also known as Australian South Sea Islanders (ASSI) and formerly referred to as Kanakas, are the Australian descendants of Pacific Islanders from more than 80 islands – including the Oceanian archipelagoes of the Solomon Islands, New Caledonia, Vanuatu, Fiji, the Gilbert Islands, and New Ireland – who were kidnapped or recruited between the mid to late 19th century as labourers in the sugarcane fields of Queensland. Some were kidnapped or tricked (or "blackbirded") into long-term indentured servitude or slavery, despite the Slavery Abolition Act 1833 criminalising slavery in Australia and other parts of the British Empire. At its height, the recruiting accounted for over half the adult male population of some islands.

Today, the majority of South Sea Islanders are also Aboriginal Australians or Torres Strait Islanders. As of the 2021 census, there were 7,228 people who claimed South Sea Islander ancestry in Australia, 5,562 of whom lived in Queensland. However, this is lower than the actual number of people with South Sea Islander heritage, with the true number estimated to be as high as 20,000 in Queensland alone as of 2022. The largest South Sea Islanders community is in the city of Mackay, where approximately 5,000 South Sea Islanders reside (approximately 5.93% of Mackay's population).

Norfolk Island (/ˈnɔːrfək/ NOR-fək, locally /ˈnɔːrfoʊk/ NOR-fohk; Norf'k Ailen) is an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, 1,412 kilometres (877 mi) directly east of Australia's Evans Head and about 900 kilometres (560 mi) from Lord Howe Island. Together with the neighbouring Phillip Island and Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 census, it had 2,188 inhabitants living on a total area of about 35 km (14 sq mi). Its capital is Kingston.

East Polynesians were the first to settle Norfolk Island, but they had already departed when Great Britain settled it as part of its 1788 colonisation of Australia. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when descendants of the Bounty mutineers were relocated from Pitcairn Island. In 1914, the UK handed Norfolk Island over to Australia, but did not Annex it to Australia, requiring it to only manage its requirements, not own it, as an external territory.

Burnt Pine (Norf'k: Ban Pain) is the largest town on Norfolk Island, an Australian external territory located in the Pacific Ocean between New Caledonia and New Zealand. It is the main commercial hub of the island, and travel from one side of the island to another generally involves passing through Burnt Pine as the island's sole thoroughfare runs through the town's centre.

The Australasian realm is one of eight biogeographic realms that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas.

The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceanian realm.

The Islamic religion is followed by a relatively small proportion of the population of Oceania. By 2010 estimates, there were 620,156 Muslims in Oceania as a whole: 476,600 in Australia, 48,151 in New Zealand, 52,520 in Fiji, 6,352 in New Caledonia, 2,200 in Papua New Guinea, 360 in Solomon Islands, 221 in Vanuatu, 110 in Tonga.

According to a 2007 article in Pacific Magazine, entitled 'Green Moon Rising', Islam has seen a substantial increase in adherents amongst the peoples of Vanuatu, Fiji, Solomon Islands, Papua New Guinea and New Caledonia. There have been thousands of indigenous converts to Islam in Melanesia.
