Context: Western Australia (abbreviated as WA) is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Southern Ocean to the south, the Northern Territory to the north-east and South Australia to the south-east. Western Australia is Australia's largest state with a total land area of 2,529,875 square kilometres (976,790 sq mi), and the second-largest country subdivision in the world  however, a significant part of it is sparsely populated. The state has about 2.6 million inhabitants, around 11% of the national total. 92% of the population lives in the south-west corner of the state., Cook is a railway station and crossing loop on the standard gauge Trans - Australian Railway from Port Augusta to Kalgoorlie , with no inhabited places around . It is 826 kilometres ( 513 mi ) by rail from Port Augusta , and is connected to the Eyre Highway by an unsealed road about 100 kilometres ( 60 mi ) long ., Adelaide is the capital city of the state of South Australia, and the fifth-most populous city of Australia. In June 2014, Adelaide had an estimated resident population of 1.31 million. South Australia, with a total of 1.7 million inhabitants, has the most centralised population of any state in Australia, with more than 75 percent of its people living in greater Adelaide, while the other population centres in the state are relatively small., Edward John Eyre (5 August 1815  30 November 1901) was an English land explorer of the Australian continent, colonial administrator, and a controversial Governor of Jamaica., Eyre Peninsula is a triangular peninsula in South Australia. It is bounded on the east by Spencer Gulf, the west by the Great Australian Bight, and the north by the Gawler Ranges. It is named after explorer Edward John Eyre who explored parts of the region in 1839-1841. The coastline was first charted by the expeditions of Matthew Flinders in 1801-1802 and French explorer Nicolas Baudin around the same time. The region's economy is primarily agricultural, with growing aquaculture, mining and tourism sectors. The main townships are Port Lincoln in the south, Whyalla and Port Augusta at the north east, and Ceduna at the northwest.
Naming and extent.
Eyre Peninsula was named after Edward John Eyre, the explorer, on 7 November 1839 by George Gawler, the second Governor of South Australia.
The peninsulas extent has been described as follows. Firstly, its coastline boundary was defined in 1839 as boundary is Spencer's Gulf in its whole length, to the southern ocean from Cape Catastrophe to the western point of Denial Bay. Secondly, its northern boundary was described in 1978 as follows - no official boundary ever proclaimed but the common sense choice would be to draw a straight line from Yorkey Crossing to the northern most point of Denial Bay., The Nullarbor Plain (; Latin: "nullus", "no", and "arbor", "tree") is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coast with the Great Victoria Desert to its north. It is the world's largest single exposure of limestone bedrock, and occupies an area of about . At its widest point, it stretches about from east to west across the border between South Australia and Western Australia., Port Augusta is a small city in South Australia. It is a seaport and railway junction city mainly located on the east coast of the Spencer Gulf immediately south of the gulf's head and about north of the state capital. The suburb of Port Augusta West is located on the west side of the gulf on the Eyre Peninsula. Other major industries included, up until mid-2010s, electricity generation. At June 2015 the estimated urban population was 14,214., Gold is a chemical element with the symbol Au (from ) and the atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides)., The Goldfields-Esperance region is one of the nine regions of Western Australia. It is located in the south eastern corner of Western Australia, and comprises the local government areas of Coolgardie, Kambalda, Dundas, Esperance, Kalgoorlie-Boulder, Laverton, Leonora, Menzies, Ngaanyatjarraku and Ravensthorpe., Kalgoorlie, part of the City of Kalgoorlie-Boulder, is a city in the Goldfields-Esperance region of Western Australia, Australia, located east-northeast of Perth at the end of the Great Eastern Highway. The town was founded in 1893 during the Coolgardie gold rush, and is located close to the so-called "Golden Mile". It is also the ultimate destination of the Goldfields Water Supply Scheme and the Golden Pipeline Heritage Trail., High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of and existing lines in excess of are widely considered to be high-speed, with some extending the definition to include lower speeds in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design., The City of Kalgoorlie-Boulder is a local government area in the Goldfields-Esperance region of Western Australia, about east of the state capital, Perth. The City covers an area of , and its seat of government is the town of Kalgoorlie; all but 244 of the city's population live in either Kalgoorlie or Boulder. In terms of area, Kalgoorlie-Boulder is the largest city in Australia, and the third-largest city in the world, with a total area of 95,575 km., The standard gauge (also Stephenson gauge after George Stephenson, International gauge, or normal gauge) is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge. All high-speed rail lines (except those in Russia, Uzbekistan, and Finland) are standard gauge. The distance between the inside edges of the rails is defined to be (except in the United States, where it is still defined in Imperial and US customary units as ). It is also called the UIC gauge or UIC track gauge, the European gauge in the EU and Russia, or uniform gauge in Queensland, Australia., George Stephenson (9 June 1781  12 August 1848) was an English civil engineer and mechanical engineer who built the first public inter-city railway line in the world to use steam locomotives, the Liverpool and Manchester Railway which opened in 1830. Renowned as the "Father of Railways", the Victorians considered him a great example of diligent application and thirst for improvement, with self-help advocate Samuel Smiles particularly praising his achievements. His rail gauge of , sometimes called "Stephenson gauge", is the standard gauge by name and by convention for most of the world's railways., In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails., The Trans-Australian Railway crosses the Nullarbor Plain of Australia from Port Augusta in South Australia to Kalgoorlie in Western Australia. It includes a stretch of dead-straight track, the world's longest, between the post west of Ooldea and the post west of Loongana., Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth-most populous city in Australia, with an estimated population of 2.04 million living in Greater Perth. Perth is part of the South West Land Division of Western Australia, with the majority of the metropolitan area of Perth located on the Swan Coastal Plain, a narrow strip between the Indian Ocean and the Darling Scarp, a low coastal escarpment. The first areas settled were on the Swan River, with the city's central business district and port (Fremantle) both located on its shores. The Perth Metropolitan Region includes 30 local government areas, which themselves consist of a large number of suburbs, extending from Two Rocks in the north to Rockingham in the south, and east inland to The Lakes., Great Eastern Highway is a road that links the Western Australian capital of Perth with the city of Kalgoorlie. A key route for road vehicles accessing the eastern Wheatbelt and the Goldfields, it is the western portion of the main road link between Perth and the eastern states of Australia. The highway forms the majority of National Highway 94, although the alignment through the Perth suburbs of Guildford and Midland, and the eastern section between Coolgardie and Kalgoorlie are not included. Various segments form parts of other road routes, including National Route 1, Alternative National Route 94, and State Route 51., The Goldfields Water Supply Scheme is a pipeline and dam project that delivers potable water from Mundaring Weir in Perth to communities in Western Australia's Eastern Goldfields, particularly Coolgardie and Kalgoorlie. The project was commissioned in 1896 and was completed in 1903., Eyre Highway is a highway linking Western Australia and South Australia via the Nullarbor Plain. Signed as National Highways 1 and A1, it forms part of Highway 1 and the Australian National Highway network linking Perth and Adelaide. It was named after explorer Edward John Eyre, who was the first European to cross the Nullarbor by land, in 18401841. Eyre Highway runs from Norseman in Western Australia, past Eucla, to the state border. Continuing to the South Australian town of Ceduna, it then crosses the top of the Eyre Peninsula before reaching the city of Port Augusta in South Australia., 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., Subject: cook, Relation: located_in_the_administrative_territorial_entity, Options: (A) adelaide (B) augusta (C) australia (D) boulder (E) east (F) eu (G) finland (H) fremantle (I) golden (J) guildford (K) indian ocean (L) jamaica (M) japan (N) lincoln (O) liverpool (P) local government area (Q) manchester (R) most (S) normal (T) northern territory (U) of (V) perth (W) plain (X) post (Y) reddish (Z) river ([) road (\) south australia (]) west (^) western australia
