Augustus Poeppel was a surveyor and explorer in Australia. He surveyed the borders between South Australia and the Northern Territory. Augustus Poeppel was born in Germany in 1839, the son of an architect. Emigrating with his family in 1849, he settled in South Australia. Poeppel moved to Victoria to become architect. In 1878, after short periods in New Zealand and Western Australia, Poeppel joined the South Australian Lands Department and was soon appointed to the border surveys, he surveyed Haddon Corner. During the Queensland-Northern Territory border survey, from the 142-mile post, he suffered from trachoma and lost 13 kg in weight, forcing his withdrawal in July 1885, his health was broken and he lost sight in one eye. Poeppel retired to Melbourne where he died in 1891 aged 52. Poeppel Corner is listed in the Queensland Heritage Register. Haddon Corner is listed on the Queensland Heritage Register. There is a monument to Poeppel across the road from the Birdsville Hotel in Queensland, it was dedicated on 2 October 2003.

Four-wheel drive called 4×4 or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, is linked via a transfer case providing an additional output drive-shaft and, in many instances, additional gear ranges. A four-wheeled vehicle with torque supplied to both axles is described as "all-wheel drive". However, "four-wheel drive" refers to a set of specific components and functions, intended off-road application, which complies with modern use of the terminology. 4WD systems were used in many different vehicle platforms. There is no universally accepted set of terminology to describe the various architectures and functions; the terms used by various manufacturers reflect marketing rather than engineering considerations or significant technical differences between systems. SAE International's standard J1952 recommends only the term All-Wheel-Drive with additional sub classifications which cover all types of AWD/4WD/4x4 systems found on production vehicles.
Four-by-four or 4x4 is used to refer to a class of vehicles in general. Syntactically, the first figure indicates the total number of wheels, the second indicates the number that are powered. So 4x2 means a four-wheel vehicle that transmits engine torque to only two axle-ends: the front two in front-wheel drive or the rear two in rear-wheel drive. A 6×4 vehicle has three axles, two of which provide torque to two axle ends each. If this vehicle were a truck with dual rear wheels on two rear axles, so having ten wheels, its configuration would still be formulated as 6x4. During World War II, the U. S. military would use spaces and a capital'X' – like "4 X 2" or "6 X 4". Four-wheel drive refers to vehicles with two axles providing torque to four axle ends. In the North American market the term refers to a system, optimized for off-road driving conditions; the term "4WD" is designated for vehicles equipped with a transfer case which switches between 2WD and 4WD operating modes, either manually or automatically.
All-wheel drive was synonymous with "four-wheel drive" on four-wheeled vehicles, six-wheel drive on 6×6s, so on, being used in that fashion at least as early as the 1920s. Today in North America the term is applied to both heavy vehicles as well as light passenger vehicles; when referring to heavy vehicles the term is applied to mean "permanent multiple-wheel drive" on 2×2, 4×4, 6×6 or 8×8 drive train systems that include a differential between the front and rear drive shafts. This is coupled with some sort of anti-slip technology hydraulic-based, that allows differentials to spin at different speeds but still be capable of transferring torque from a wheel with poor traction to one with better. Typical AWD systems are not intended for more extreme off-road use; when used to describe AWD systems in light passenger vehicles, it refers to a system that applies torque to all four wheels and/or is targeted at improving on-road traction and performance, rather than for off-road applications. Some all-wheel drive electric vehicles solve this challenge using one motor for each axle, thereby eliminating a mechanical differential between the front and rear axles.
An example of this is the dual motor variant of the Tesla Model S, which on a millisecond scale can control the torque distribution electronically between its two motors. Individual-wheel drive is used to describe electric vehicles with each wheel being driven by its own electric motor; this system has inherent characteristics that would be attributed to four-wheel drive systems like the distribution of the available torque to the wheels. However, because of the inherent characteristics of electric motors, torque can be negative, as seen in the Rimac Concept One and SLS AMG Electric; this can have drastic effects, as in better handling in tight corners. The term IWD can refer to a vehicle with any number of wheels. For example, the Mars rovers are 6-wheel IWD. Per the SAE International standard J1952, AWD is the preferred term for all the systems described above; the standard subdivides AWD systems into three categories. Part-Time AWD systems require driver intervention to couple and decouple the secondary axle from the driven axle and these systems do not have a center differential.
The definition notes. Full-Time AWD systems drive both rear axles at all times via a center differential; the torque split of that differential may be fixed or variable depending on the type of center differential. This system can be used on any surface at any speed; the definition does not address exclusion of a low range gear. On-Demand AWD systems drive the secondary axle via an active or passive coupling device or "by an independently powered drive system"; the standard notes that in some cases the secondary drive system may provide the primary vehicle propulsion. An example is a hybrid AWD vehicle where the primary axle is driven by an internal combustion engine and secondary axle is driven by an electric motor; when the internal combustion engine is shut off the secondary, electrically driven axle is the only driven axle. On-demand systems function with only one powered axle until torque is required by the second axle. At that point either a passive or active coupling sends torque to the secondary axle.
In addition to the above primary classifications the J1952 standard notes seconda
Time in Australia
Australia uses three main time zones: Australian Western Standard Time, Australian Central Standard Time, Australian Eastern Standard Time. Time is regulated by the individual state governments. Australia's external territories observe different time zones. Standard time was introduced in the 1890s. Before the switch to standard time zones, each local city or town was free to determine its local time, called local mean time. Now, Western Australia uses Western Standard Time. Daylight saving time is used in states in the south and south-east - South Australia, New South Wales, Victoria and the ACT, it is not used in Western Australia, the Northern Territory or Queensland. The standardisation of time in Australia began in 1892, when surveyors from the six colonies in Australia met in Melbourne for the Intercolonial Conference of Surveyors; the delegates accepted the recommendation of the 1884 International Meridian Conference to adopt Greenwich Mean Time as the basis for standard time. The colonies enacted time zone legislation, which took effect in February 1895.
The clocks were set ahead of GMT by 8 hours in Western Australia. The three time zones became known as Western Standard Time, Central Standard Time, Eastern Standard Time. Broken Hill in the far west of New South Wales adopted Central Standard Time due to it being connected by rail to Adelaide but not Sydney at the time. On 1 May 1899 at 12:00AM local time, South Australia advanced Central Standard Time by thirty minutes after lobbying by businesses who wanted to be closer to Melbourne time and cricketers and footballers who wanted more daylight to practice in the evenings disregarding the common international practice of setting one-hour intervals between adjacent time zones. Attempts to correct these oddities in 1986 and 1994 were rejected; when the Northern Territory was separated from South Australia and placed under the jurisdiction of the Federal Government, that Territory kept Central Standard Time. When the ACT was broken off from New South Wales, it retained Eastern Standard Time. Since 1899, the only major changes in Australian time zones have been the setting of clocks to one-half hour earlier than Eastern time on the territory of Lord Howe Island, Norfolk Island changing from UTC+11:30 to UTC+11:00 on 4 October 2015.
When abbreviating "Australian Central Time" and "Australian Eastern Time", in domestic contexts the leading "Australian" may be omitted. Though the governments of the states and territories have the power to legislate variations in time, the standard time within each of these is set related to Coordinated Universal Time as determined by the International Bureau of Weights and Measures and set by section 8AA of the National Measurement Act of 1960 of the Commonwealth. Australia has kept a version of the UTC atomic time scale since the 1990s, but Greenwich Mean Time remained the formal basis for the standard times of all of the states until 2005. In November 2004, the state and territory attorneys-general endorsed a proposal from the Australian National Measurement Institute to adopt UTC as the standard of all Australian standard times, thereby eliminating the effects of slight variations in the rate of rotation of the Earth that are inherent in mean solar time. All states have adopted the UTC standard, starting on 1 September 2005.
In Victoria, South Australia and the ACT, the starting and ending dates of daylight saving times are determined by proclamations, declarations, or regulation made by the State Governor or by the responsible minister. Such instruments may be valid for only the current year, so this section only refers to the legislation. In New South Wales and Western Australia, the starting and ending dates, if any, are to be set by legislation. Western Standard Time – UTC+08:00 Western Australia – Standard Time Act 2005Central Standard Time – UTC+09:30 South Australia – Standard Time Act 2009 and the Daylight Saving Act 1971 Northern Territory – Standard Time Act 2005Eastern Standard Time – UTC+10:00 Queensland – Standard Time Act 1894 New South Wales – Standard Time Act 1987 No 149 Australian Capital Territory – Standard Time and Summer Time Act 1972 Victoria – Summer Time Act 1972 Tasmania – Standard Time Act 1895 and the Daylight Saving Act 2007 The choice of whether to use DST is a matter for the governments of the individual states and territories.
However, during World War I and World War II all states and territories used daylight saving time. In 1968 Tasmania became the first state in peacetime to use DST, followed in 1971 by New South Wales, Queensland, South Australia, the Australian Capital Territory. Western Australia and the Northern Territory did not adopt it. Queensland abandoned DST in 1972. Queensland and Western Australia have used DST during the past 40 years during trial periods; the main DST zones are the following: Central Daylight Saving Time – UTC+10:30, in South Australia Eastern Daylight Saving Time – UTC+11:00, in New South Wales, the ACT, TasmaniaDuring the usual
Western Australia is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of 2,529,875 square kilometres, the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic; the state has about 2.6 million inhabitants – around 11 percent of the national total – of whom the vast majority live in the south-west corner, 79 per cent of the population living in the Perth area, leaving the remainder of the state sparsely populated. The first European visitor to Western Australia was the Dutch explorer Dirk Hartog, who visited the Western Australian coast in 1616; the first European settlement of Western Australia occurred following the landing by Major Edmund Lockyer on 26 December 1826 of an expedition on behalf of the New South Wales colonial government.
He established a convict-supported military garrison at King George III Sound, at present-day Albany, on 21 January 1827 formally took possession of the western third of the continent for the British Crown. This was followed by the establishment of the Swan River Colony in 1829, including the site of the present-day capital, Perth. York was the first inland settlement in Western Australia. Situated 97 kilometres east of Perth, it was settled on 16 September 1831. Western Australia achieved responsible government in 1890 and federated with the other British colonies in Australia in 1901. Today, its economy relies on mining, agriculture and tourism; the state produces 46 per cent of Australia's exports. Western Australia is the second-largest iron ore producer in the world. Western Australia is bounded to the east by longitude 129°E, the meridian 129 degrees east of Greenwich, which defines the border with South Australia and the Northern Territory, bounded by the Indian Ocean to the west and north.
The International Hydrographic Organization designates the body of water south of the continent as part of the Indian Ocean. The total length of the state's eastern border is 1,862 km. There are 20,781 km including 7,892 km of island coastline; the total land area occupied by the state is 2.5 million km2. The bulk of Western Australia consists of the old Yilgarn craton and Pilbara craton which merged with the Deccan Plateau of India and the Karoo and Zimbabwe cratons of Southern Africa, in the Archean Eon to form Ur, one of the oldest supercontinents on Earth. In May 2017, evidence of the earliest known life on land may have been found in 3.48-billion-year-old geyserite and other related mineral deposits uncovered in the Pilbara craton. Because the only mountain-building since has been of the Stirling Range with the rifting from Antarctica, the land is eroded and ancient, with no part of the state above 1,245 metres AHD. Most of the state is a low plateau with an average elevation of about 400 metres low relief, no surface runoff.
This descends sharply to the coastal plains, in some cases forming a sharp escarpment. The extreme age of the landscape has meant that the soils are remarkably infertile and laterised. Soils derived from granitic bedrock contain an order of magnitude less available phosphorus and only half as much nitrogen as soils in comparable climates in other continents. Soils derived from extensive sandplains or ironstone are less fertile, nearly devoid of soluble phosphate and deficient in zinc, copper and sometimes potassium and calcium; the infertility of most of the soils has required heavy application by farmers of fertilizers. These have resulted in damage to bacterial populations; the grazing and use of hoofed mammals and heavy machinery through the years have resulted in compaction of soils and great damage to the fragile soils. Large-scale land clearing for agriculture has damaged habitats for native fauna; as a result, the South West region of the state has a higher concentration of rare, threatened or endangered flora and fauna than many areas of Australia, making it one of the world's biodiversity "hot spots".
Large areas of the state's wheatbelt region have problems with dryland salinity and the loss of fresh water. The southwest coastal area has a Mediterranean climate, it was heavily forested, including large stands of karri, one of the tallest trees in the world. This agricultural region is one of the nine most bio-diverse terrestrial habitats, with a higher proportion of endemic species than most other equivalent regions. Thanks to the offshore Leeuwin Current, the area is one of the top six regions for marine biodiversity and contains the most southerly coral reefs in the world. Average annual rainfall varies from 300 millimetres at the edge of the Wheatbelt region to 1,400 millimetres in the wettest areas near Northcliffe, but from November to March, evaporation exceeds rainfall, it is very dry. Plants are adapted to this as well as the extreme poverty of all soils; the central two-thirds of the state is sparsely inhabited. The only significant economic activity is mining. Annual rainfall averages less than 300 millimetres, most of which occurs in sporadic torrential falls related to cyclone events in summer.
An exception to this is
Geography of Australia
The geography of Australia encompasses a wide variety of biogeographic regions being the world's smallest continent but the sixth-largest country in the world. The population of Australia is concentrated along the southeastern coasts; the geography of the country is diverse, ranging from the snow-capped mountains of the Australian Alps and Tasmania to large deserts and temperate forests. Neighbouring countries include Indonesia, East Timor and Papua New Guinea to the north, the Solomon Islands and the French dependency of New Caledonia to the east, New Zealand to the southeast. Australia is a continent and an island, it is located in Oceania between the the South Pacific Ocean. It is the sixth largest country in the world with a total area of 7,686,850 square kilometres, making it smaller than the 48 states of the contiguous United States and 31.5 times larger than the United Kingdom. The Australian mainland has a total coastline length of 35,877 km with an additional 23,859 km of island coastlines.
There are 758 estuaries around the country with most located in the sub-tropical zones. Australia claims an extensive Exclusive Economic Zone of 8,148,250 square kilometres; this exclusive economic zone does not include the Australian Antarctic Territory. Australia has the largest area of ocean jurisdiction of any country on earth, it has no land borders. The northernmost points of the country are the Cape York Peninsula of Queensland and the Top End of the Northern Territory; the western half of Australia consists of the Western Plateau, which rises to mountain heights near the west coast and falls to lower elevations near the continental centre. The Western Plateau region is flat, though broken by various mountain ranges such as the Hamersley Range, the MacDonnell Ranges, the Musgrave Range. Surface water is lacking in the Western Plateau, although there are several larger rivers in the west and north, such as the Murchison and Victoria river; the Eastern Highlands, or Great Dividing Range, lie near the eastern coast of Australia, separating the narrow eastern coastal plain from the rest of the continent.
These Eastern Australian temperate forests have the greatest relief, the most rainfall, the most abundant and varied flora and fauna, the densest human settlement. Between the Eastern Highlands and the Western Plateau, lie the Central Lowlands, which are made up of the Great Artesian Basin and Australia's largest river systems, Murray-Darling Basin and Lake Eyre Basin. Off the eastern coast of Australia is the world's largest coral reef complex, the Great Barrier Reef; the State of Tasmania, a large and mountainous island, resides in the south-eastern corner of Australia. Australia is the lowest and oldest continental landmass on Earth and it has had a stable geological history. Geological forces such as tectonic uplift of mountain ranges or clashes between tectonic plates occurred in Australia's early history, when it was still a part of Gondwana, its highest peak is Mount Kosciuszko at 2,228 metres, low in comparison to the highest mountains on other continents. Charles Rowland Twidale estimates that between 10 and 20% of Australia's modern landscapes formed during the Mesozoic when the continent was part of Gondwana.
Australia is situated in the middle of the tectonic plate, therefore has no active volcanism. Minor earthquakes which produce no damage occur while major earthquakes measuring greater than magnitude 6 occur on average every five years; the terrain is low plateau with deserts, rangelands and a fertile plain in the southeast. Tasmania and the Australian Alps do not contain any permanent icefields or glaciers, although they may have existed in the past; the Great Barrier Reef, by far the world's largest coral reef, lies a short distance off the north-east coast. The Australian continental landmass consists of six distinct landform divisions; these are: The Eastern Highlands—including the Great Dividing Range, the fertile Brigalow Belt strip of grassland behind the east coast, the Eastern Uplands The Eastern alluvial Plains and Lowlands—the Murray Darling basin covers the southern part. The headwaters of some waterways are located in tropical regions where summer rains create a high rate of discharge.
Flood events drastically alter the dry environment in which the ecology of central Australia has had to adapt to the boom and bust cycle. The Great Artesian Basin is an important source of water, the world's largest and deepest fresh water basin. Access to water from the basin has led to the expansion of grazing into areas that were far too dry for livestock. Towns and cities across the country sometimes face major water storage and usage crises in which restrictions and other measures are implemented to reduce water consumption. Water restrictions are based on a gradient of activities that become progressively banned as the situation worsens. Billabong is the Australian name given to the oxbow lakes that can form along a meandering river's course. In a worldwide comparison of height, Australia's waterfalls are insignificant, with the longest
New South Wales
New South Wales is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south, South Australia to the west, its coast borders the Tasman Sea to the east. The Australian Capital Territory is an enclave within the state. New South Wales' state capital is Sydney, Australia's most populous city. In September 2018, the population of New South Wales was over 8 million, making it Australia's most populous state. Just under two-thirds of the state's population, 5.1 million, live in the Greater Sydney area. Inhabitants of New South Wales are referred to as New South Welshmen; the Colony of New South Wales was founded as a penal colony in 1788. It comprised more than half of the Australian mainland with its western boundary set at 129th meridian east in 1825; the colony included the island territories of New Zealand, Van Diemen's Land, Lord Howe Island, Norfolk Island. During the 19th century, most of the colony's area was detached to form separate British colonies that became New Zealand and the various states and territories of Australia.
However, the Swan River Colony has never been administered as part of New South Wales. Lord Howe Island remains part of New South Wales, while Norfolk Island has become a federal territory, as have the areas now known as the Australian Capital Territory and the Jervis Bay Territory; the prior inhabitants of New South Wales were the Aboriginal tribes who arrived in Australia about 40,000 to 60,000 years ago. Before European settlement there were an estimated 250,000 Aboriginal people in the region; the Wodi Wodi people are the original custodians of the Illawarra region of South Sydney. Speaking a variant of the Dharawal language, the Wodi Wodi people lived across a large stretch of land, surrounded by what is now known as Campbelltown, Shoalhaven River and Moss Vale; the Bundjalung people are the original custodians of parts of the northern coastal areas. The European discovery of New South Wales was made by Captain James Cook during his 1770 survey along the unmapped eastern coast of the Dutch-named continent of New Holland, now Australia.
In his original journal covering the survey, in triplicate to satisfy Admiralty Orders, Cook first named the land "New Wales", named after Wales. However, in the copy held by the Admiralty, he "revised the wording" to "New South Wales"; the first British settlement was made by. After years of chaos and anarchy after the overthrow of Governor William Bligh, a new governor, Lieutenant-Colonel Lachlan Macquarie, was sent from Britain to reform the settlement in 1809. During his time as governor, Macquarie commissioned the construction of roads, wharves and public buildings, sent explorers out from Sydney and employed a planner to design the street layout of Sydney. Macquarie's legacy is still evident today. During the 19th century, large areas were successively separated to form the British colonies of Tasmania, South Australia and Queensland. Responsible government was granted to the New South Wales colony in 1855. Following the Treaty of Waitangi, William Hobson declared British sovereignty over New Zealand in 1840.
In 1841 it was separated from the Colony of New South Wales to form the new Colony of New Zealand. Charles Darwin visited Australia in January 1836 and in The Voyage of the Beagle records his hesitations about and fascination with New South Wales, including his speculations about the geological origin and formation of the great valleys, the aboriginal population, the situation of the convicts, the future prospects of the country. At the end of the 19th century, the movement toward federation between the Australian colonies gathered momentum. Conventions and forums involving colony leaders were held on a regular basis. Proponents of New South Wales as a free trade state were in dispute with the other leading colony Victoria, which had a protectionist economy. At this time customs posts were common on borders on the Murray River. Travelling from New South Wales to Victoria in those days was difficult. Supporters of federation included the New South Wales premier Sir Henry Parkes whose 1889 Tenterfield Speech was pivotal in gathering support for New South Wales involvement.
Edmund Barton to become Australia's first Prime Minister, was another strong advocate for federation and a meeting held in Corowa in 1893 drafted an initial constitution. In 1898 popular referenda on the proposed federation were held in New South Wales, South Australia and Tasmania. All votes resulted in a majority in favour, but the New South Wales government under Premier George Reid had set a requirement for a higher "yes" vote than just a simple majority, not met. In 1899 further referenda were held in the same states as well as Queensland. All resulted in yes votes with majorities increased from the previous year. New South Wales met the conditions; as a compromise to the question on where the capital was to be located, an agreement was made that the site was to be within New South Wales but not closer than 100 miles from Sydney, while the provisional capital would be Melbourne. The area that now forms the Australian Capital Territory was ceded by New South Wales when Canberra was selected.
In the years after World War I, the high prices enjoyed durin
Australia the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area; the neighbouring countries are Papua New Guinea and East Timor to the north. The population of 25 million is urbanised and concentrated on the eastern seaboard. Australia's capital is Canberra, its largest city is Sydney; the country's other major metropolitan areas are Melbourne, Brisbane and Adelaide. Australia was inhabited by indigenous Australians for about 60,000 years before the first British settlement in the late 18th century, it is documented. After the European exploration of the continent by Dutch explorers in 1606, who named it New Holland, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788, a date which became Australia's national day; the population grew in subsequent decades, by the 1850s most of the continent had been explored and an additional five self-governing crown colonies established.
On 1 January 1901, the six colonies federated. Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy, comprising six states and ten territories. Being the oldest and driest inhabited continent, with the least fertile soils, Australia has a landmass of 7,617,930 square kilometres. A megadiverse country, its size gives it a wide variety of landscapes, with deserts in the centre, tropical rainforests in the north-east and mountain ranges in the south-east. A gold rush began in Australia in the early 1850s, its population density, 2.8 inhabitants per square kilometre, remains among the lowest in the world. Australia generates its income from various sources including mining-related exports, telecommunications and manufacturing. Indigenous Australian rock art is the oldest and richest in the world, dating as far back as 60,000 years and spread across hundreds of thousands of sites. Australia is a developed country, with the world's 14th-largest economy.
It has a high-income economy, with the world's tenth-highest per capita income. It is a regional power, has the world's 13th-highest military expenditure. Australia has the world's ninth-largest immigrant population, with immigrants accounting for 26% of the population. Having the third-highest human development index and the eighth-highest ranked democracy globally, the country ranks in quality of life, education, economic freedom, civil liberties and political rights, with all its major cities faring well in global comparative livability surveys. Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development, World Trade Organization, Asia-Pacific Economic Cooperation, Pacific Islands Forum and the ASEAN Plus Six mechanism; the name Australia is derived from the Latin Terra Australis, a name used for a hypothetical continent in the Southern Hemisphere since ancient times. When Europeans first began visiting and mapping Australia in the 17th century, the name Terra Australis was applied to the new territories.
Until the early 19th century, Australia was best known as "New Holland", a name first applied by the Dutch explorer Abel Tasman in 1644 and subsequently anglicised. Terra Australis still saw occasional usage, such as in scientific texts; the name Australia was popularised by the explorer Matthew Flinders, who said it was "more agreeable to the ear, an assimilation to the names of the other great portions of the earth". The first time that Australia appears to have been used was in April 1817, when Governor Lachlan Macquarie acknowledged the receipt of Flinders' charts of Australia from Lord Bathurst. In December 1817, Macquarie recommended to the Colonial Office. In 1824, the Admiralty agreed that the continent should be known by that name; the first official published use of the new name came with the publication in 1830 of The Australia Directory by the Hydrographic Office. Colloquial names for Australia include "Oz" and "the Land Down Under". Other epithets include "the Great Southern Land", "the Lucky Country", "the Sunburnt Country", "the Wide Brown Land".
The latter two both derive from Dorothea Mackellar's 1908 poem "My Country". Human habitation of the Australian continent is estimated to have begun around 65,000 to 70,000 years ago, with the migration of people by land bridges and short sea-crossings from what is now Southeast Asia; these first inhabitants were the ancestors of modern Indigenous Australians. Aboriginal Australian culture is one of the oldest continual civilisations on earth. At the time of first European contact, most Indigenous Australians were hunter-gatherers with complex economies and societies. Recent archaeological finds suggest. Indigenous Australians have an oral culture with spiritual values based on reverence for the land and a belief in the Dreamtime; the Torres Strait Islanders, ethnically Melanesian, obtained their livelihood from seasonal horticulture and the resources of their reefs and seas. The northern coasts and waters of Australia were visited s
