55-642: The Fremantle Doctor , the Freo Doctor , or simply The Doctor , is the Western Australian vernacular term for the cooling afternoon sea breeze that occurs during summer months in south west coastal areas of Western Australia. The sea breeze occurs because of the major temperature difference between the land and sea. The name was in use as early as the 1870s and was similar to equivalent terms for winds that occurred in South Africa and

Kwinana also hosts alumina and nickel processing plants, port facilities for grain and other bulk exports, and support industries for mining and petroleum such as heavy and light engineering, and metal fabrication. Shipbuilding (e.g. Austal ) and associated support industries are found at nearby Henderson , just north of Kwinana. Significant secondary industries include cement and building product manufacturing, flour milling, food processing, animal feed production, automotive body building and printing. Western Australia has

Products for local consumption and export include western rock lobsters , prawns, crabs, shark and tuna, as well as pearl fishing in the Kimberley region of the state. Processing is conducted along the west coast. Whaling was a key marine industry but ceased at Albany in 1978. Western Australia has the world's biggest plantations of both Indian sandalwood (northern WA) and Australian sandalwood (semi-arid regions), which are used to produce sandalwood oil and incense . The WA sandalwood industry provides about 40% of

The population of the division is about 2.2 million people, with 1.8 million living in
825-456: Is strongest in December and January, when the temperature differential between the land and ocean is greatest. In February and March the breeze is not as strong, because the ocean is a bit warmer. Though October and November are not as warm, the ocean is cooler, resulting in the sea breeze in these months. Other months have a weak or non-existent Fremantle Doctor. In the winter months, the land

The Kimberley has an extremely hot monsoonal climate with average annual rainfall ranging from 500 to 1,500 millimetres (20–60 in), but there is a very long almost rainless season from April to November. Eighty-five percent of the state's runoff occurs in the Kimberley, but because it occurs in violent floods and because of the insurmountable poverty of
935-555: Is usually cooler than the ocean, and this sometimes results in the weaker land breeze in the early morning. When the Fremantle Doctor first arrives it is from the west-south-west direction. Later when it is at maximum strength, the direction is usually from the southwest or south-south-west. By the early evening, the direction is from the south. This change in wind direction is due to the Coriolis effect . Other factors, like
990-556: The Freycinet Map of 1811 , the first published map featuring the full outline of Australia. The name New Holland remained in popular and semi-official use until at least the mid-1850s; that is, it was in use for about 206 years in comparison to the name Australia which to date has been in use for about 195 years. The origins of the present state began with the establishment by Lockyer of a convict-supported settlement from New South Wales at King George III Sound . The settlement
1045-641: The Group Settlement Scheme of the 1920s, which encouraged farmers to settle the southwest—increased awareness of Australia's western third as a destination for colonists. Led by immigrants from the British Isles, Western Australia's population developed at a faster rate during the twentieth century than it had previously. After World War II , both the eastern states and Western Australia received large numbers of Italians , Croatians and Macedonians . Despite this, Britain has contributed
1100-1072: The Hamersley Range of the Pilbara region). Most of the state is a low plateau with an average elevation of about 400 metres (1,200 ft), very low relief, and no surface runoff . This descends relatively sharply to the coastal plains, in some cases forming a sharp escarpment (as with the Darling Range/ Darling Scarp near Perth). The extreme age of the landscape has meant that the soils are remarkably infertile and frequently laterised . Even 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 even less fertile, nearly devoid of soluble phosphate and deficient in zinc , copper, molybdenum and sometimes potassium and calcium . The infertility of most of
1155-576: The Swan River Colony was established on the Swan River by Captain James Stirling . By 1832, the British settler population of the colony had reached around 1,500, and the official name of the colony was changed to Western Australia on 6 February that year. The two separate townsites of the colony developed slowly into the port city of Fremantle and the state's capital, Perth . York was
