The country lies within the north temperate zone and has a changeable, maritime climate. The Coral Sea is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. New South Wales (abbreviated as NSW) is a state on the east coast of :Australia. It borders Queensland to the north, Victoria to the south, and South Australia to the west. It has a coast line with the Tasman Sea on its east side. The Australian Capital Territory is an enclave within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. , the estimated population of New South Wales was 7.5 million, making it Australia's most populous state. Just under two-thirds of the state's population, 4.67 million, live in the Greater Sydney area. Inhabitants of New South Wales are referred to as "New South Welshmen". Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite (Al(OH)), boehmite (-AlO(OH)) and diaspore (-AlO(OH)), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase (TiO) and ilmenite (FeTiO or FeO.TiO). In 1821 the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. In 1861, French chemist Henri Sainte-Claire Deville named the mineral "bauxite". South Australia (abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories. It has a total of 1.7 million people, and its population is the most highly centralised of any state in Australia, with more than 75 percent of South Australians living in the capital, Adelaide, or its environs. Other population centres in the state are relatively small. Uranium is a chemical element with symbol U and atomic number 92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all its isotopes are unstable (with half-lives of the six naturally known isotopes, uranium-233 to uranium-238, varying between 69 years and 4.5 billion years). The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99%) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. Brisbane is the capital and most populous city in the Australian state of Queensland, and the third most populous city in Australia. Brisbane's metropolitan area has a population of 2.3 million, and the South East Queensland urban conurbation, centred on Brisbane, encompasses a population of more than 3.4 million.

The Tasman Sea (Mori: "Te Tai-o-Rehua") is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about across and about from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who was the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration. Rio Tinto is a British-Australian multinational and one of the world's largest metals and mining corporations. The company was founded in 1873, when a multinational consortium of investors purchased a mine complex on the Rio Tinto, in Huelva, Spain, from the Spanish government. Since then, the company has grown through a long series of mergers and acquisitions to place itself among the world leaders in the production of many commodities, including aluminium, iron ore, copper, uranium, coal, and diamonds. Although primarily focused on extraction of minerals, Rio Tinto also has significant operations in refining, particularly for refining bauxite and iron ore. The company has operations on six continents, but is mainly concentrated in Australia and Canada, and owns its mining operations through a complex web of wholly and partly owned subsidiaries.
  Rio Tinto has joint head offices in London (global and "plc") & Melbourne ("Limited" - Australia). Queensland (abbreviated as QLD) is the second-largest and third-most-populous state in the Commonwealth of Australia.

Often referred to as the "Sunshine State", Queensland is home to 10 of Australia's 30 largest cities and is the nation's third largest economy. Tourism in the state, fuelled largely by its warm tropical climate, is a major industry.
