New Guinea

Raja Ampat, or the Four Kings, is an archipelago located off the northwest tip of Bird's Head Peninsula on the island of New Guinea, in Indonesia's Southwest Papua province. It comprises over 1,500 small islands, cays, and shoals surrounding the four main islands of Misool, Salawati, Batanta, and Waigeo, and the smaller island of Kofiau.

Biak is an island located in Cenderawasih Bay near the northern coast of Papua, an Indonesian province, and is just northwest of New Guinea. Biak is the largest island in its small archipelago, and has many atolls, reefs, and corals.

Malay is an Austronesian language that is an official language of Brunei, Indonesia, Malaysia, and Singapore, and that is also spoken in East Timor and parts of the Philippines and Thailand. Altogether, it is spoken by 290 million people across Maritime Southeast Asia.

The Portuguese Empire, also known as the Portuguese Overseas or the Portuguese Colonial Empire, was composed of the overseas colonies, factories, and the later overseas territories governed by Portugal. It was one of the longest-lived empires in European history, lasting almost six centuries from the conquest of Ceuta in North Africa, in 1415, to the transfer of sovereignty over Macau to China in 1999. The empire began in the 15th century, and from the early 16th century it stretched across the globe, with bases in Africa, North America, and South America, and various regions of Asia and Oceania.

The Maluku Islands or the Moluccas are an archipelago in the east of Indonesia. Tectonically they are located on the Halmahera Plate within the Molucca Sea Collision Zone. Geographically they are located east of Sulawesi, west of New Guinea, and north and east of Timor. Lying within Wallacea, the Maluku Islands have been considered as a geographical and cultural intersection of Asia and Oceania.

Guinea is a traditional name for the region of the African coast of West Africa which lies along the Gulf of Guinea. It is a naturally moist tropical forest or savanna that stretches along the coast and borders the Sahel belt in the north.

Dark skin is a type of human skin color that is rich in melanin pigments. People with very dark skin are often referred to as "black people", although this usage can be ambiguous in some countries where it is also used to specifically refer to different ethnic groups or populations.

Jacob Le Maire was a Dutch mariner who circumnavigated the earth in 1615 and 1616. The strait between Tierra del Fuego and Isla de los Estados was named the Le Maire Strait in his honour, though not without controversy. It was Le Maire himself who proposed to the council aboard Eendracht that the new passage should be called by his name and the council unanimously agreed with Le Maire. The author or authors of The Relation took Eendracht captain Willem Schouten's side by proclaiming:“ ... our men had each of them three cups of wine in signe of ioy for our good hap ... [and the naming of] the Straights of Le Maire, although by good right it should rather have been called Willem Schouten Straight, after our Masters Name, by whose wise conduction and skill in sayling, the same was found.”.

The Schouten Islands are an island group of Papua province, eastern Indonesia in the Cenderawasih Bay 50 km off the north-western coast of the island of New Guinea. The group consists of the main islands of Biak, Supiori and Numfor, and numerous smaller islands, mostly covered in rain forest.

Oceania is a geographical region that is described as a continent in some parts of the world. It includes Australasia, Melanesia, Micronesia, and Polynesia. Spanning the Eastern and Western Hemispheres, Oceania is estimated to have a land area of 8,525,989 square kilometres (3,291,903 sq mi) and a population of around 44.4 million as of 2022. While in most of the English-speaking world Oceania is described as a geographical region, outside of the English-speaking world Oceania is described as one of the continents. In this model of the world, Australia is only seen as an island nation contained inside of the continent of Oceania, and not a continent by itself. When compared to the other continents, Oceania is the smallest in land area and the second least populated after Antarctica.

Australasia is a region that comprises Australia, New Zealand and some neighbouring islands in the Pacific Ocean. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different, but related regions.

Micronesia is a subregion of Oceania, consisting of about 2,000 small islands in the North western Pacific Ocean. It has a close shared cultural history with three other island regions: Maritime Southeast Asia to the west, Polynesia to the east, and Melanesia to the south—as well as with the wider community of Austronesian peoples.

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.

The geography of Australia encompasses a wide variety of biogeographic regions being the world's smallest continent, while comprising the territory of the sixth-largest country in the world. The population of Australia is concentrated along the eastern and south-eastern coasts. The geography of the continent is extremely diverse, ranging from the snow-capped mountains of the Australian Alps and Tasmania to large deserts, tropical and temperate forests, grasslands, heathlands and woodlands.

This list of highest mountains of New Guinea shows all mountains on the island of New Guinea that are at least 3750 m high and have a topographic prominence of 500 m or more. These c. 50 peaks are also the highest mountains of Australasia and the continent of Australia, where, outside New Guinea, the highest mountain is Aoraki / Mount Cook in New Zealand with a height of 3724 m. A list of highest mountains of Oceania with the same limitations is almost identical, with the addition of the Hawaiian volcanoes of Mauna Kea and Mauna Loa in 18th and 20th positions. The list also shows the 36 highest thus defined mountains of Indonesia, except for the 3805 m high Gunung Kerinci on Sumatra, and the 16 highest mountains of Papua New Guinea.

Mainland Australia is the main landmass of the Australian continent, excluding the Aru Islands, New Guinea, Tasmania, and other Australian offshore islands. The landmass also constitutes the mainland of the territory governed by the Commonwealth of Australia, and the term, along with continental Australia, can be used in a geographic sense to exclude surrounding continental islands and external territories. Generally, the term is applied to the states of New South Wales, Queensland, South Australia, Victoria, and Western Australia, as well as the Australian Capital Territory, Jervis Bay Territory, and Northern Territory.

The Arafura Sea lies west of the Pacific Ocean, overlying the continental shelf between Australia and Western New Guinea, which is the Indonesian part of the Island of New Guinea.

The Coral Sea is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends 2,000 kilometres (1,200 mi) down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia.

The Gulf of Carpentaria is a large, shallow sea enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea. The northern boundary is generally defined as a line from Slade Point, Queensland in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory in the west.

Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.

The Bismarck Archipelago is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about 50,000 square km.

The Malay Archipelago or also called the Indo-Australian Archipelago is the archipelago between Mainland Southeast Asia and Australia. It has also been called the "Malay world," "Nusantara", "East Indies" and other names over time. The name was taken from the 19th-century European concept of a Malay race, later based on the distribution of Austronesian languages.

Geologically, the Sahul Shelf is a part of the continental shelf of the Australian continent, lying off the northwest coast of mainland Australia.

The Last Glacial Period (LGP), also known colloquially as the last ice age or simply ice age, occurred from the end of the Eemian to the end of the Younger Dryas, encompassing the period c. 115,000 – c. 11,700 years ago. The LGP is part of a larger sequence of glacial and interglacial periods known as the Quaternary glaciation which started around 2,588,000 years ago and is ongoing. The definition of the Quaternary as beginning 2.58 million years ago (Mya) is based on the formation of the Arctic ice cap. The Antarctic ice sheet began to form earlier, at about 34 Mya, in the mid-Cenozoic. The term Late Cenozoic Ice Age is used to include this early phase. The previous ice age, the Saale glaciation, which ended about 128,000 years ago, was more severe than the Last Glacial Period in some areas such as Britain, but less severe in others.

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.

Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Living marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, and bandicoots among others, while many extinct species, such as the thylacine, are also known.

Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas. However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos.

Monotremes are prototherian mammals of the order Monotremata. They are one of the three groups of living mammals, along with placentals (Eutheria), and marsupials (Metatheria). Monotremes are typified by structural differences in their brains, jaws, digestive tract, reproductive tract, and other body parts, compared to the more common mammalian types. In addition, they lay eggs rather than bearing live young, but, like all mammals, the female monotremes nurse their young with milk.

Echidnas, sometimes known as spiny anteaters, are quill-covered monotremes belonging to the family Tachyglossidae. The four extant species of echidnas and the platypus are the only living mammals that lay eggs and the only surviving members of the order Monotremata. The diet of some species consists of ants and termites, but they are not closely related to the true anteaters of the Americas, which are xenarthrans. Echidnas live in Australia and New Guinea.

Placental mammals are one of the three extant subdivisions of the class Mammalia, the other two being Monotremata and Marsupialia. Placentalia contains the vast majority of extant mammals, which are partly distinguished from monotremes and marsupials in that the fetus is carried in the uterus of its mother to a relatively late stage of development. The name is something of a misnomer considering that marsupials also nourish their fetuses via a placenta, though for a relatively briefer period, giving birth to less developed young which are then nurtured for a period inside the mother's pouch.

The New Guinea singing dog or New Guinea Highland dog is an ancient (basal) lineage of dog found in the New Guinea Highlands, on the island of New Guinea. Once considered to be a separate species in its own right, under the name Canis hallstromi, it is closely related to the Australian dingo. The dog is unique among canines, as it is one of the few to be considered "barkless", and known for its unusual "yodel"-like style of vocalizing.

The Pleistocene is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek πλεῖστος, pleīstos, 'most' and καινός, kainós, 'new'.

New Zealand is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island and the South Island —and over 700 smaller islands. It is the sixth-largest island country by area, covering 268,021 square kilometres (103,500 sq mi). New Zealand is about 2,000 kilometres (1,200 mi) east of Australia across the Tasman Sea and 1,000 kilometres (600 mi) south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.

Highland Papua is a province of Indonesia, which roughly follows the borders of Papuan customary region of Lano-Pago, shortened to La Pago. It covers an area of 51,213.34 km2 (19,773.58 sq mi) and had a population of 1,430,459 according to the official estimates as at mid 2022.

Central Papua, officially the Central Papua Province is an Indonesian province located in the central region of Western New Guinea. It was formally established on 11 November 2022 from the former eight western regencies of the province of Papua. It covers an area of 61,072.92 km2 and had an officially estimated population of 1,430,951 in mid 2022. It is bordered by the Indonesian provinces of West Papua to the west, the residual Papua to the north, and by Highland Papua and South Papua to the east.

Formally established on 11 November 2022 and including the four most southern regencies that were previously part of the province of Papua and before 11 December 2002 were all part of a larger Merauke Regency, it covers an area of 117,849.16 km2 and had a population of 522,215 according to the official estimates for mid 2022.

The 141st meridian east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, the Pacific Ocean, Australasia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole.

The Fly River is the third longest river in the island of New Guinea, after the Sepik River and Mamberamo River, with a total length of 1,060 km (660 mi). It is the largest by volume of discharge in Oceania, the largest in the world without a single dam in its catchment, and overall the 20th-largest primary river in the world by discharge volume. It is located in the southwest of Papua New Guinea and in the Papua Province of Indonesia. It rises in the Victor Emanuel Range arm of the Star Mountains, and crosses the south-western lowlands before flowing into the Gulf of Papua in a large delta. The Fly-Strickland River system has a total length of 1,220 km (760 mi), making it the longest river system of an island in the world. The 824 km (512 mi) Strickland River is the longest and largest tributary of Fly River, making it the farthest distance source of the Fly River.

The Dutch Empire or the Dutch colonial empire comprised the overseas territories and trading posts controlled and administered by Dutch chartered companies—mainly the Dutch East India Company and the Dutch West India Company—and subsequently by the Dutch Republic (1581–1795), and by the modern Kingdom of the Netherlands after 1815. It was initially a trade-based system which derived most of its influence from merchant enterprise and from Dutch control of international maritime shipping routes through strategically placed outposts, rather than from expansive territorial ventures. The Dutch were among the earliest empire-builders of Europe, following Spain and Portugal and one of the wealthiest nations of that time.

The Dutch East Indies, also known as the Netherlands East Indies, was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800.

Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at 1,904,569 square kilometres. With over 275 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population.

Manokwari is a coastal town and the capital of the Indonesian province of West Papua. It is one of only seven provincial capitals of Indonesia without a city status. It is also the administrative seat of Manokwari Regency. However, under proposals currently under consideration by the Indonesian Parliament, it is planned to split Manokwari town off from the regency and turn it into a separate city. The majority of Manokwari residents are Christians and the town is one of the seats of the Roman Catholic Diocese of Manokwari–Sorong.

Jayapura is the capital and largest city of the Indonesian province of Papua. It is situated on the northern coast of New Guinea island and covers an area of 940.0 km2 (362.9 sq mi). The city borders the Pacific Ocean and Yos Sudarso Bay to the north, the sovereign state of Papua New Guinea to the east, Keerom Regency to the south, and Jayapura Regency to the west.

Wamena is a town and the capital of the Indonesian province of Highland Papua. It also serves as the seat of Jayawijaya Regency. It is the largest town in Indonesian Papua's highlands, in the Baliem Valley and had a population of 64,967 at the 2020 Census. Wamena is the urban centre of a rural area housing highland Papua's highest concentration of population, with over 300,000 people inhabiting the Baliem Valley and surrounding areas. These people belong to a number of related ethnic groups, the most prominent of which are Dani, Lani and Yali.

The Dani people are a people from the Central Highlands of Western New Guinea in Baliem Valley, Highland Papua, Indonesia. They are sometimes conflated with the Lani group to the west.

The Baliem Valley is a valley of the Central Highlands in Western New Guinea. Specifically in Highland Papua, Indonesia. The main town in the valley is Wamena, which lies on the Baliem River. The valley is about 80 km in length by 20 km in width and lies at an altitude of about 1,600–1,700 metres (5,200–5,600 ft), with a population of over 200,000.

Ethnologue: Languages of the World is an annual reference publication in print and online that provides statistics and other information on the living languages of the world. It is the world's most comprehensive catalogue of languages. It was first issued in 1951, and is now published by SIL International, an American Christian non-profit organization.

Papua New Guinea, officially the Independent State of Papua New Guinea, is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia. Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of 462,840 km2 (178,700 sq mi).

The Austronesian languages are a language family widely spoken throughout Maritime Southeast Asia, Madagascar, the islands of the Pacific Ocean and Taiwan. There are also a number of speakers in continental Asia. They are spoken by about 386 million people. This makes it the fifth-largest language family by number of speakers. Major Austronesian languages include Malay, Javanese, Sundanese, and Tagalog (Filipino). According to some estimates, the family contains 1,257 languages, which is the second most of any language family.

The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent 26 ka - 20 ka, during an interval of low obliquity. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts, along with a large drop in sea levels. Based on changes in position of ice sheet margins dated via terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets commenced 33,000 years ago and maximum coverage was between 26,500 years and 19–20,000 years ago, when deglaciation commenced in the Northern Hemisphere, causing an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fluctuations around the Strait of Magellan suggest the peak in glacial surface area was constrained to between 25,200 and 23,100 years ago. Continental ice sheets never reached their isostatic equilibrium during the LGM, as evidenced by high variability in ice volume over short spans of time.

In biogeography, a land bridge is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonize new lands. A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age.

The continent of Australia, sometimes known in technical contexts by the names Sahul, Australia-New Guinea, Australinea, Meganesia, or Papualand to distinguish it from the country of Australia, is located within the Southern and Eastern hemispheres. The name "Sahul" takes its name from the Sahul Shelf, which is a part of the continental shelf of the Australian continent. The continent includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands. Situated in the geographical region of Oceania, Australia is the smallest of the seven traditional continents.

The Malay Archipelago or also called the Indo-Australian Archipelago is the archipelago between Mainland Southeast Asia and Australia. It has also been called the "Malay world," "Nusantara", "East Indies" and other names over time. The name was taken from the 19th-century European concept of a Malay race, later based on the distribution of Austronesian languages.

The Korowai, also called the Kolufo, are the people who live in southeastern Papua in the Indonesian provinces of South Papua and Highland Papua. Specifically their tribal area is split by the borders of Boven Digoel Regency, Mappi Regency, Asmat Regency, and Yahukimo Regency. They number about 3,000 people.

New Ireland, or Latangai, is a large island in Papua New Guinea, approximately 7,404 km2 (2,859 sq mi) in area with c. 120,000 people. It is named after the island of Ireland. It is the largest island of New Ireland Province, lying northeast of the island of New Britain. Both islands are part of the Bismarck Archipelago, named after Otto von Bismarck, and they are separated by Saint George's Channel.

New Britain is the largest island in the Bismarck Archipelago, part of the Islands Region of Papua New Guinea. It is separated from New Guinea by a northwest corner of the Solomon Sea and from New Ireland by St. George's Channel. The main towns of New Britain are Rabaul/Kokopo and Kimbe. The island is roughly the size of Taiwan. While the island was part of German New Guinea, it was named Neupommern . In common with most of the Bismarcks it was largely formed by volcanic processes, and has active volcanoes including Ulawun, Langila, the Garbuna Group, the Sulu Range, and the volcanoes Tavurvur and Vulcan of the Rabaul caldera. A major eruption of Tavurvur in 1994 destroyed the East New Britain provincial capital of Rabaul. Most of the town still lies under metres of ash, and the capital has been moved to nearby Kokopo.

The fauna of New Guinea comprises a large number of species of mammals, reptiles, birds, fish, invertebrates and amphibians.

Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level.

The Aru Islands Regency is a group of about 95 low-lying islands in the Maluku Islands of eastern Indonesia. It also forms a regency of Maluku Province, with a land area of 6,426.77 square kilometres. At the 2011 Census the Regency had a population of 84,138; the 2020 Census produced a total of 102,237. Some sources regard the archipelago as part of Asia, while others regard it as part of Melanesia.

The Bismarck Archipelago is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about 50,000 square km.

The Louisiade Archipelago is a string of ten larger volcanic islands frequently fringed by coral reefs, and 90 smaller coral islands in Papua New Guinea.

Madagascar, officially the Republic of Madagascar is a sovereign island country in the Indian Ocean, approximately 400 kilometres off the coast of East Africa across the Mozambique Channel. At 592,800 square kilometres (228,900 sq mi), it is the world's second-largest island country, after Indonesia. Its capital and largest city is Antananarivo.

Borneo is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra.

Java is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population.

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms.

The Australasian realm is a biogeographic realm that is coincident with, but not the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea, and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccas, and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas.

The Malay Peninsula is a peninsula in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung). The island country of Singapore also has historical and cultural ties with the region. The indigenous people of the peninsula are the Malays, an Austronesian people.

The prehistory of Papua New Guinea can be traced to about 50,000–60,000 years ago, when people first migrated towards the Australian continent. The written history began when European navigators first sighted New Guinea in the early part of the 17th century.

The indigenous peoples of Western New Guinea in Indonesia and Papua New Guinea, commonly called Papuans, are Melanesians. There is genetic evidence for two major historical lineages in New Guinea and neighboring islands: a first wave from the Malay Archipelago perhaps 50,000 years ago when New Guinea and Australia were a single landmass called Sahul and, much later, a wave of Austronesian people from the north who introduced Austronesian languages and pigs about 3,500 years ago. They also left a small but significant genetic trace in many coastal Papuan peoples.

The New Guinea Highlands, also known as the Central Range or Central Cordillera, is a long chain of mountain ranges on the island of New Guinea, including the island's tallest peak, Puncak Jaya, Indonesia, 16,024 ft (4,884 m), the highest mountain in Oceania. The range is home to many intermountain river valleys, many of which support thriving agricultural communities. The highlands run generally east-west the length of the island, which is divided politically between Indonesia in the west and Papua New Guinea in the east.

The Casuarinaceae are a family of dicotyledonous flowering plants placed in the order Fagales, consisting of four genera and 91 species of trees and shrubs native to eastern Africa, Australia, Southeast Asia, Malesia, Papuasia, and the Pacific Islands. At one time, all species were placed in the genus Casuarina. Lawrence Alexander Sidney Johnson separated out many of those species and renamed them into the new genera of Gymnostoma in 1980 and 1982, Allocasuarina in 1982, and Ceuthostoma in 1988, with some additional formal descriptions of new species in each other genus. At the time, it was somewhat controversial. The monophyly of these genera was later supported in a 2003 genetics study of the family. In the Wettstein system, this family was the only one placed in the order Verticillatae. Likewise, in the Engler, Cronquist, and Kubitzki systems, the Casuarinaceae were the only family placed in the order Casuarinales.

The Austronesian peoples, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples in Taiwan, Maritime Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia.

Maritime Southeast Asia comprises the countries of Brunei, Indonesia, Malaysia, the Philippines, Singapore, and East Timor. Maritime Southeast Asia is sometimes also referred to as Island Southeast Asia, Insular Southeast Asia or Oceanic Southeast Asia. The 16th-century term "East Indies" and the later 19th-century term "Malay Archipelago" are also used to refer to Maritime Southeast Asia.

Java is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population.

Borneo is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra.

The Lorentz River is located in the Indonesian province of South Papua in Western New Guinea, about 3,500 km northeast of the Indonesian capital Jakarta. It originates in the central east-west mountain range of New Guinea, and flows southwards into the Arafura Sea at Flamingo Bay. During the first two Dutch expeditions to Southern New Guinea (1907–10) it was called Northern River. In 1910 it was renamed after the Dutch explorer Hendrikus Albertus Lorentz. After it became part of Indonesia, it was renamed to Unir, as in the language of the local Asmat people, while the Lorentz name is still in use.

The Nagarakretagama or Nagarakṛtāgama, also known as Desawarnana or Deśavarṇana, is an Old Javanese eulogy to Hayam Wuruk, a Javanese king of the Majapahit Empire. It was written on lontar as a kakawin by Mpu Prapanca in 1365. The Nagarakretagama contains detailed descriptions of the Majapahit Empire during its greatest extent. The poem affirms the importance of Hindu–Buddhism in the Majapahit empire by describing temples and palaces and several ceremonial observances.
