Presbyterianism (pres-bə-TE-ree-a-nizm) is a historically Reformed Protestant tradition named after its form of church government by representative assemblies of elders, known as "presbyters". Though other Reformed churches are structurally similar, the word Presbyterian is applied to churches that trace their roots to the Church of Scotland or to English Dissenter groups that were formed during the English Civil War, 1642 to 1651.

Presbyterian theology typically emphasises the sovereignty of God, the authority of the Scriptures, and the necessity of grace through faith in Christ. Scotland ensured Presbyterian church government in the 1707 Acts of Union, which created the Kingdom of Great Britain. In fact, most Presbyterians in England have a Scottish connection. The Presbyterian denomination was also taken to North America, Australia, and New Zealand, mostly by Scots and Scots-Irish immigrants. Scotland's Presbyterian denominations hold to the Reformed theology of John Calvin and his immediate successors, although there is a range of theological views within contemporary Presbyterianism. Local congregations of churches that use Presbyterian polity are governed by sessions made up of representatives of the congregation (elders), a conciliar approach as with other levels of decision-making (presbytery, synod, and general assembly). There are roughly 75 million Presbyterians in the world.

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.

Melanesia is a subregion of Oceania in the southwestern Pacific Ocean. It extends from New Guinea in the west to the Fiji Islands in the east, and includes the Arafura Sea. Melanesia borders Southeast Asia to the west, Polynesia to the east, Micronesia to the north and Australia to the south.

New Caledonia is a French territory comprising a group of islands in the southwest Pacific Ocean, 220 km (140 mi) southwest of Vanuatu and 1,210 km (750 mi) east of Australia. Located 16,100 km (10,000 mi) from Metropolitan France, it forms a sui generis collectivity of the French Republic, a legal status unique in overseas France, enshrined in a dedicated chapter of the French Constitution and with an on-going project to a status of State of New Caledonia.

The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre le Caillou, a nickname also used more generally for the entire New Caledonia. Pro-independence Kanak parties use the name (la) Kanaky (pron. [(la) kanaki]) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indigenous Melanesian Kanak people who make up 41% of New Caledonia's population. New Caledonia is associated with the European Union as an overseas country and territory (OCT).

Papua New Guinea (PNG), officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises the eastern half of the island of New Guinea and offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. It has a land border with Indonesia to the west and maritime borders with Australia to the south and the Solomon Islands to the east. Its capital is Port Moresby. The country's 462,840 km (178,700 sq mi) includes a large mainland and hundreds of islands. The majority of the country's land is held under the collective customary ownership of local clans. This protected tenure is globally exceptional due to remarkable legislative protections granted in PNG’s national constitution.

The territory of Papua New Guinea was split in the 1880s between German New Guinea in the north and the British Territory of Papua in the south, the latter of which was ceded to Australia in 1902. All of present-day Papua New Guinea came under Australian control following World War I, although it remained two distinct territories. The nation was the site of fierce fighting during the New Guinea campaign of World War II, following which the two territories were united in 1949. Papua New Guinea became an independent Commonwealth realm in 1975. Representing the King is a Governor-General. Politics takes place within a Westminster system, with the government led by a Prime Minister. Members of the national parliament also serve as provincial leaders.

The Anglosphere, also known as the Anglo-American world, is a Western-led sphere of influence among Anglophone countries. The core group of this sphere of influence comprises five developed countries that maintain close social, cultural, political, economic, and military ties with each other: Australia, Canada, New Zealand, the United Kingdom, and the United States. Although extended definitions do include non-Western and developing countries that were once part of the British Empire and retained English influence and common law upon independence, the Anglosphere is a distinct grouping that is not simply synonymous with countries in which the English language has official status.

Anglosphere countries are generally aligned with each other on global issues and collaborate extensively in matters of security, as exemplified by alliances like Five Eyes. The core countries of the Anglosphere are either NATO members or designated by the United States as major non-NATO allies.

Modern English, sometimes called New English (NE) or present-day English (PDE) as opposed to Middle and Old English, is the form of the English language that has been spoken since the Great Vowel Shift in England, which began in the late 14th century and was completed by the 17th century.

With some differences in vocabulary, texts that date from the early 17th century, such as the works of William Shakespeare and the King James Bible, are considered Modern English, or more specifically, Early Modern English or Elizabethan English. Through colonization, the British Empire spread English to many regions of the world, such as Anglo-America, the Indian subcontinent, Africa, Australia and New Zealand.

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.

Tasmania (/tæzˈmeɪniə/; palawa kani: Lutruwita) is an island state of Australia. It is located 240 kilometres (150 miles) to the south of the Australian mainland, and is separated from it by the Bass Strait. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 1000 islands. It is Australia's smallest and least populous state, with 573,479 residents as of June 2023. The state capital and largest city is Hobart, with around 40% of the population living in the Greater Hobart area. Tasmania is the most decentralised state in Australia, with the lowest proportion of its residents living within its capital city.

Tasmania's main island was first inhabited by Aboriginal peoples, who today generally identify as Palawa or Pakana. It is believed that Aboriginal Tasmanians became isolated from mainland Aboriginal groups around 11,700 years ago, when rising sea levels formed Bass Strait.
