History Of Immigration To Australia
The immigration history of Australia began with the initial human migration to the continent around 80,000 years ago when the ancestors of Aboriginal Australians arrived on the continent via the islands of Maritime Southeast Asia and New Guinea. From the early 17th century onwards, the continent experienced the first coastal landings and exploration by European explorers. Permanent European settlement began in 1788 with the establishment of a British penal colony in New South Wales. From early federation in 1901, Australia maintained the White Australia Policy, which was abolished after World War II, heralding the modern era of multiculturalism in Australia. From the late 1970s there was a significant increase in immigration from Asian and other non-European countries. Australia is also a signatory to the Convention Relating to the Status of Refugees and recognises the right of asylum. Original inhabitants The first inhabitants in Australia were the ancestors of the present ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Migration
Human migration is the movement of people from one place to another with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is also possible; indeed, this is the dominant form of human migration globally. Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move. It has a high potential to improve human development, and some studies confirm that migration is the most direct route out of poverty.Age is also important for both work and non-work migration. People may migrate as individuals, in family units or in large groups. There are four major forms of migration: invasion, conquest, colonization and emigration/immigration. Persons moving from their home due to forced displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Melanesia
Melanesia (, ) is a subregion of Oceania in the southwestern Pacific Ocean. It extends from Indonesia's New Guinea in the west to Fiji in the east, and includes the Arafura Sea. The region includes the four independent countries of Fiji, Vanuatu, the Solomon Islands, and Papua New Guinea. It also includes the French oversea collectivity of New Caledonia, Indigenous Australians of the Torres Strait Islands and parts of Indonesia, most notably the provinces of Central Papua, Highland Papua, Papua, South Papua, Southwest Papua, and West Papua. Almost all of the region is in the Southern Hemisphere; only a few small islands that are not politically considered part of Oceania—specifically the northwestern islands of Western New Guinea—lie in the Northern Hemisphere. The name ''Melanesia'' (in French, ''Mélanésie'') was first used in 1832 by French navigator Jules Dumont d'Urville: he coined the terms ''Melanesia'' and '' Micronesia'' along the preexisting '' Polyne ...

Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. 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.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York ().

Timeline Of Glaciation
There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago. Within ice ages, there exist periods of more severe glacial conditions and more temperate conditions, referred to as glacial periods and interglacial periods, respectively. The Earth is currently in such an interglacial period of the Quaternary glaciation, with the last glacial period of the Quaternary having ended approximately 11,700 years ago. The current interglacial is known as the Holocene epoch.Walker, M., Johnsen, S., Rasmussen, S. O., Popp, T., Steffensen, J.-P., Gibbard, P., Hoek, W., Lowe, J., Andrews, J., Bjo¨ rck, S., Cwynar, L.

Swan River (Western Australia)
The Swan River () is a river in the south west of Western Australia. The river runs through the metropolitan area of Perth, Western Australia's capital and largest city. Course of river The Swan River estuary flows through the city of Perth. Its lower reaches are relatively wide and deep, with few constrictions, while the upper reaches are usually quite narrow and shallow. The Swan River drains the Avon and coastal plain catchments, which have a total area of about . It has three major tributaries, the Avon River, Canning River and Helena River. The latter two have dams (Canning Dam and Mundaring Weir) which provide a sizeable part of the potable water requirements for Perth and the regions surrounding. The Avon River contributes the majority of the freshwater flow. The climate of the catchment is Mediterranean, with mild wet winters, hot dry summers, and the associated highly seasonal rainfall and flow regime. The Avon rises near Yealering, southeast of Perth: it meand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torres Strait
The Torres Strait (), also known as Zenadh Kes, is a strait between Australia and the Melanesian island of New Guinea. It is wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost extremity of the Australian mainland. To the north is the Western Province of Papua New Guinea. It is named after the Spanish navigator Luís Vaz de Torres, who sailed through the strait in 1606. Prehistory The islands of the Torres Strait have been inhabited by humans for at least 2,500 years and possibly much longer. The various Torres Strait Islander communities have a unique culture and long-standing history with the islands and nearby coastlines. Their maritime-based trade and interactions with the Papuans to the north and the Australian Aboriginal communities have maintained a steady cultural diffusion among the three societal groups, dating back thousands of years. History The first recorded European navigation of the strait was by Luís Vaz de Torres, a pilot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Carpentaria
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 body of water that lies between Australia and New Guinea). The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land) in the west. At its mouth, the Gulf is wide, and further south, . The north-south length exceeds . It covers a water area of about . The general depth is between and does not exceed . The tidal range in the Gulf of Carpentaria is between . The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef provinc ...

Arafura Sea
The Arafura Sea (or Arafuru Sea) lies west of the Pacific Ocean, overlying the continental shelf between Australia and Western New Guinea (also called Papua), which is the Indonesian part of the Island of New Guinea. Geography The Arafura Sea is bordered by the Gulf of Carpentaria and the continent of Australia to the south, the Timor Sea to the west, the Banda and Seram seas to the northwest, and the Torres Strait to the east. (Just across the strait, farther to the east, lies the Coral Sea). The Arafura Sea is long and wide. The depth of the sea is in most places, with the depth increasing to the west. The sea lies over the Arafura Shelf, which is a section of the Sahul Shelf. When sea levels were low during the last glacial maximum, the Arafura Shelf, the Gulf of Carpentaria and the Torres Strait formed a large, flat, land bridge that connected Australia and New Guinea and eased the migration of humans from Asia into Australia. The combined landmass formed the continent of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Bridge
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 Colonisation (biology), 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. Prominent examples * Adam's Bridge (also known as Rama Setu), connecting India and Sri Lanka * The Bass Strait#Discovery and exploration, Bassian Plain, which linked Australia and Tasmania * The Beringia, Bering Land Bridge (aka Beringia), which intermittently connected Alaska (Northern America) with Siberia (North Asia) as sea levels rose and fell under the effect of ice ages * East Asia’s former unnamed landmass, During the last Ice Age, which ended approximately 15,000 years ago, Japanese Archipela ...
