The continent includes a [[continental shelf]] overlain by shallow seas which divide it into several landmasses—the [[Arafura Sea]] and [[Torres Strait]] between mainland Australia and New Guinea, and [[Bass Strait]] between mainland Australia and Tasmania. When [[sea level]]s were lower during the [[quaternary glaciation|Pleistocene ice age]], including the [[Last Glacial Maximum]] about 18,000 BC, they were connected by dry land into the combined landmass of [[Sahul]]. The name "Sahul" derives from the [[Sahul Shelf]], which is a part of the continental shelf of the Australian continent. During the past 18,000 to 10,000 years, rising sea levels overflowed the lowlands and separated the continent into today's low-lying [[arid]] to [[semi-arid climate|semi-arid]] mainland and the two mountainous islands of New Guinea and Tasmania.

The American author [[Samuel Griswold Goodrich]] wrote in his 1854 book ''History of All Nations'' that, "geographers have agreed to consider the island world of the Pacific Ocean as a third continent, under the name Oceania."

In the quest for [[Terra Australis]], Spanish explorations in the 17th century, such as the expedition led by the Portuguese navigator [[Pedro Fernandes de Queirós]], discovered the [[Pitcairn Islands|Pitcairn]] and [[Vanuatu]] archipelagos, and sailed the [[Torres Strait]] between [[Australia]] and [[New Guinea]], named after navigator [[Luís Vaz de Torres]], who was the first European to explore the Strait. When [[Europe]]ans first arrived, inhabitants of New Guinea and nearby islands, whose technologies included bone, wood, and stone tools, had a productive agricultural system. In 1660, the Dutch recognised the Sultan of [[Tidore]]'s sovereignty over [[New Guinea]].

From that point a system of [[federalism in Australia]] came into operation, entailing the establishment of an entirely new national government (the Commonwealth government) and an ongoing division of powers between that government and the States. With the encouragement of Queensland, in 1884, a [[British protectorate]] had been proclaimed over the southern coast of New Guinea and its adjacent islands. [[British New Guinea]] was annexed outright in 1888. The possession was placed under the authority of the newly federated Commonwealth of Australia in 1902 and with passage of the Papua Act of 1905, British New Guinea became the Australian [[Territory of Papua]], with formal Australian administration beginning in 1906.<ref>{{cite web |url=https://2009-2017.state.gov/r/pa/ei/bgn/2797.htm |title=Papua New Guinea |publisher=State.gov |date=8 October 2010 |access-date=14 July 2011}}</ref>

For about 40 million years Australia–New Guinea was almost completely isolated. During this time, the continent experienced numerous changes in climate, but the overall trend was towards greater aridity. When [[South America]] eventually separated from Antarctica, the development of the cold [[Antarctic Circumpolar Current]] changed weather patterns across the world. For Australia–New Guinea, it brought a marked intensification of the drying trend. The great inland seas and lakes dried out. Much of the long-established broad-leaf [[deciduous]] forest began to give way to the distinctive hard-leaved [[sclerophyllous]] plants that characterise the modern Australian landscape.

Typical Southern Hemisphere flora include the [[conifer]]s ''[[Podocarpus]]'' (eastern Australia and New Guinea), the rainforest emergents ''[[Araucaria]]'' (eastern Australia and New Guinea), ''[[Nothofagus]]'' (New Guinea and [[Tasmania]]) and ''[[Agathis]]'' (northern [[Queensland]] and New Guinea), as well as [[tree fern]]s and several species of ''Eucalyptus''. Prominent features of the Australian flora are adaptations to [[aridity]] and fire which include [[sclerophyll|scleromorphy]] and [[serotiny]]. These adaptations are common in species from the large and well-known families [[Proteaceae]] (''[[Banksia]]s'' and ''[[Grevillea]]s''), [[Myrtaceae]] (''[[Eucalyptus]]'' or gum trees, ''[[Melaleuca]]s'' and ''[[Callistemon]]s''), [[Fabaceae]] (''[[Acacia]]''s or wattles), and [[Casuarinaceae]] (''[[Casuarina]]s'' or she-oaks), which are typically found in the Australian mainland. The flora of New Guinea is a mixture of many [[tropical rainforest]] species with origins in Asia, such as ''[[Castanopsis acuminatissima]],'' ''[[Lithocarpus]]'' spp., [[Elaeocarpaceae|elaeocarps]], and [[Lauraceae|laurels]], together with typically Australasian flora. In the New Guinean highlands, conifers such as ''[[Dacrycarpus]], [[Dacrydium]], [[Papuacedrus]]'' and ''[[Libocedrus]]'' are present.<ref>{{cite web |url=http://www.publish.csiro.au/samples/australiaburningsample.pdf |title=Australia Burning: Fire Ecology, Policy and Management Issues |publisher=CSIRO Publishing}}</ref>

For many species, the primary refuge was the relatively cool and well-watered [[Great Dividing Range]]. Even today, pockets of remnant vegetation remain in the cool uplands, some species not much changed from the Gondwanan forms of 60 or 90 million years ago. Eventually, the Australia–New Guinea tectonic plate collided with the [[Eurasian plate]] to the north. The collision caused the northern part of the continent to buckle upwards, forming the high and rugged mountains of New Guinea and, by reverse (downwards) buckling, the [[Torres Strait]] that now separates the two main landmasses. The collision also pushed up the islands of [[Wallacea]], which served as island 'stepping-stones' that allowed plants from [[Southeast Asia]]'s rainforests to colonise New Guinea, and some plants from Australia–New Guinea to move into Southeast Asia. The ocean straits between the islands were narrow enough to allow plant dispersal, but served as an effective barrier to exchange of land mammals between Australia–New Guinea and Asia. Among the fungi, the remarkable association between ''[[Cyttaria]]'' ''gunnii'' (one of the "golf-ball" fungi) and its associated trees in the genus ''[[Nothofagus]]'' is evidence of that drift: the only other places where this association is known are New Zealand and southern [[Argentina]] and [[Chile]].<ref>{{cite book |last=Korf |first=R.

As the continent drifted north from Antarctica, a unique [[Fauna (animals)|fauna]], [[Flora (plants)|flora]] and [[Fungi|mycobiota]] developed. [[Marsupial]]s and [[monotreme]]s also existed on other continents, but only in Australia–New Guinea did they out-compete the [[Placentalia|placental]] [[mammals]] and come to dominate. New Guinea has 284 species and six orders of mammals: monotremes, three orders of marsupials, [[rodent]]s and [[bat]]s; 195 of the mammal species (69%) are endemic. New Guinea has a rich diversity of [[coral]] life and 1,200 species of [[fish]] have been found. Also about 600 species of reef-building coral—the latter equal to 75 percent of the world's known total. New Guinea has 578 species of breeding birds, of which 324 species are endemic. [[Aves|Bird]] life also flourished—in particular, the [[songbird]]s (order [[Passerine|Passeriformes]], suborder Passeri) are thought to have evolved 50 million years ago in the part of [[Gondwana]] that later became [[Australia]], New Zealand, [[New Guinea]], and [[Antarctica]], before radiating into a great number of different forms and then spreading around the globe.<ref name=Low>{{Citation

Animal groups such as [[Macropodidae|macropods]], [[monotremes]], and [[Cassowary|cassowaries]] are endemic to Australia. There were three main reasons for the enormous diversity that developed in animal, fungal and plant life.

* While much of the rest of the world underwent significant cooling and thus loss of species diversity, Australia–New Guinea was drifting north at such a pace that the overall global cooling effect was roughly equalled by its gradual movement toward the [[equator]]. [[Temperature]]s in Australia–New Guinea, in other words, remained reasonably constant for a very long time, and a vast number of different animal, fungal and plant species were able to evolve to fit particular [[ecological niche]]s. Because the continent was more isolated than any other, very few outside species arrived to colonise, and unique native forms developed unimpeded.
* Finally, despite the fact that the continent was already very old and thus relatively infertile, there are dispersed areas of high fertility. Where other continents had [[Volcanism|volcanic]] activity and/or massive [[Glacier|glaciation]] events to turn over fresh, unleached [[Rock (geology)|rock]]s rich in [[mineral]]s, the rocks and [[soil]]s of Australia–New Guinea were left largely untouched except by gradual [[erosion]] and deep [[weathering]]. In general, fertile soils produce a profusion of life, and a relatively large number of species/level of biodiversity. This is because where [[nutrient]]s are plentiful, competition is largely a matter of outcompeting rival species, leaving great scope for innovative [[co-evolution]] as is witnessed in tropical, fertile ecosystems. In contrast, infertile soils tend to induce competition on an abiotic basis meaning individuals all face constant environmental pressures, leaving less scope for divergent evolution, a process instrumental in creating new species.

Although New Guinea is the most northerly part of the continent, and could be expected to be the most [[tropical climate|tropical]] in climate, the altitude of the New Guinea highlands is such that a great many animals and plants that were once common across Australia–New Guinea now survive only in the tropical highlands where they are severely threatened by [[population growth]].

===Climate===
{{Main|Climate of Australia}}

In New Guinea, the climate is mostly [[monsoonal]] (December to March), southeast monsoon (May to October), and [[tropical rainforest climate|tropical rainforest]] with slight seasonal temperature variation. In lower altitudes, the temperature is around {{convert|27|C|F}} year round. But the higher altitudes, such as [[Mendi]], are constantly around {{convert|21|C|F}} with cool lows nearing {{convert|11|C|F}}, with abundant rainfall and high humidity. The [[New Guinea Highlands]] are one of the few regions close to the [[equator]] that experience [[snowfall]], which occurs in the most elevated parts of the mainland.

Papua New Guinea is a [[Commonwealth realm]]. As such, King [[Charles III]] is its sovereign and head of state. The constitutional convention, which prepared the draft constitution, and Australia, the outgoing metropolitan power, had thought that Papua New Guinea would not remain a monarchy. The founders, however, considered that imperial honours had a cachet.<ref>{{cite book |last=Bradford |first=Sarah |url=https://archive.org/details/elizabethbiograp00brad_0 |title=Elizabeth: A Biography of Britain's Queen |publisher=Riverhead Books |year=1997 |isbn=978-1-57322-600-4}}</ref> The monarch is represented by the [[Governor-General of Papua New Guinea]], currently [[Bob Dadae]]. Papua New Guinea (along with [[Solomon Islands]]) is unusual among Commonwealth realms in that governors-general are elected by the legislature, rather than chosen by the executive branch.

Papua New Guinea is rich in natural resources, which account for two-thirds of their export earnings. Though PNG is filled with resources, the lack of country's development led foreign countries to take over few sites and continued foreign demand for PNG's resources and as a result, the United States constructed an oil company and began to export in 2004 and this was the largest project in PNG's history.<ref>{{cite web|url=https://www.cia.gov/the-world-factbook/countries/papua-new-guinea/|title=The World Factbook|website=www.cia.gov|access-date=14 March 2016}}</ref><ref>{{cite web|url=http://www.apecpng2018.org/|title=APECPNG2018.ORG|website=www.apecpng2018.org|access-date=29 August 2016|archive-date=9 July 2016|archive-url=https://web.archive.org/web/20160709114755/http://apecpng2018.org/|url-status=dead}}</ref> Papua New Guinea is classified as a [[Developing country|developing economy]] by the [[International Monetary Fund]].<ref>[http://www.imf.org/external/pubs/ft/weo/2015/02/weodata/weorept.aspx?sy=2014&ey=2014&ssd=1&sort=country&ds=.&br=1&pr1.x=16&pr1.y=7&c=512%2C668%2C914%2C672%2C612%2C946%2C614%2C137%2C311%2C962%2C213%2C674%2C911%2C676%2C193%2C548%2C122%2C556%2C912%2C678%2C313%2C181%2C419%2C867%2C513%2C682%2C316%2C684%2C913%2C273%2C124%2C868%2C339%2C921%2C638%2C948%2C514%2C943%2C218%2C686%2C963%2C688%2C616%2C518%2C223%2C728%2C516%2C558%2C918%2C138%2C748%2C196%2C618%2C278%2C522%2C692%2C622%2C694%2C156%2C142%2C624%2C449%2C626%2C564%2C628%2C565%2C228%2C283%2C924%2C853%2C233%2C288%2C632%2C293%2C636%2C566%2C634%2C964%2C238%2C182%2C662%2C453%2C960%2C968%2C423%2C922%2C935%2C714%2C128%2C862%2C611%2C135%2C321%2C716%2C243%2C456%2C248%2C722%2C469%2C942%2C253%2C718%2C642%2C724%2C643%2C576%2C939%2C936%2C644%2C961%2C819%2C813%2C172%2C199%2C132%2C733%2C646%2C184%2C648%2C524%2C915%2C361%2C134%2C362%2C652%2C364%2C174%2C732%2C328%2C366%2C258%2C734%2C656%2C144%2C654%2C146%2C336%2C463%2C263%2C528%2C268%2C923%2C532%2C738%2C944%2C578%2C176%2C537%2C534%2C742%2C536%2C866%2C429%2C369%2C433%2C744%2C178%2C186%2C436%2C925%2C136%2C869%2C343%2C746%2C158%2C926%2C439%2C466%2C916%2C112%2C664%2C111%2C826%2C298%2C542%2C927%2C967%2C846%2C443%2C299%2C917%2C582%2C544%2C474%2C941%2C754%2C446%2C698%2C666&s=PPPPC&grp=0&a= World Economic Outlook Database, October 2015], [http://www.imf.org/external/ns/cs.aspx?id=28 International Monetary Fund].

It is estimated that more than 7,000 different cultural groups exist in Papua New Guinea, and most groups have their own language. Because of this diversity, in which they take pride, many different styles of cultural expression have emerged; each group has created its own expressive forms in [[art]], [[performance art]], [[weapon]]ry, [[costume]]s and [[architecture]]. Papua New Guinea is one of the few cultures in Oceania to practice the tradition of [[bride price]].<ref>{{cite web |title=Papua New Guinea – culture |work=Datec Pty Ltd |url=http://www.datec.com.au/png/culture.htm |access-date=16 December 2005 |archive-url=https://web.archive.org/web/19990210114159/http://www.datec.com.au/png/culture.htm |archive-date=10 February 1999}}</ref> In particular, Papua New Guinea is world-famous for carved wooden [[sculpture]]: masks, canoes, story-boards.
