South Australia

G'day and welcome to my South Australia information page. Here you will find some information about South Australia, some sights from around the state as well as links to other related sites.

South Australia has boundaries with other States on the west, north and east and on the south is flanked by the Southern Ocean. It has a total area of 984 377 km², representing one eighth of the Australian continent. More than 50 per cent is pastoral land, with 6.5 per cent of the State designated as national parks and wildlife reserves. Most of the population lives in the southern coastal zones below the 32nd parallel.

South Australia is a land of generally low relief with the inland area largely covered by plains, sand and gibber deserts. The coastline has a south-easterly north-westerly trend, interrupted by two major indentations, Spencer Gulf between Eyre and Yorke Peninsulas, and Gulf St Vincent between Yorke Peninsula and the Fleurieu Peninsula. To the south of Gulf St Vincent is Kangaroo Island, about 480 km in circumference. It is the largest of the 100 or so islands on the South Australian coastline.

The most important mountains are the Mt Lofty-Flinders Ranges system, which extends north about 800 km from Cape Jervis to the northern end of Lake Torrens. In the south, the Mt Lofty Ranges are of comparatively low altitude, the highest peak being Mt Lofty at 727 m. To the north, the Flinders Ranges are of greater height, with St Mary's Peak the highest point at 1166 m. The Flinders Ranges contain unusual basins, of which Wilpena Pound is the best known.

The River Murray, which drains about one seventh of Australia, enters the sea in South Australia and is the state's only major river. For 216 km to Overland Corner, the river occupies a wide valley, then passes through a narrow, steep-sided valley to Lake Alexandrina and Lake Albert at its heavily silted mouth.

Surrounding the northern Flinders Ranges is a series of vast lakes which fill only after heavy rain, normally appearing as shallow depressions with salt or clay encrusted surfaces. The largest of these, Lake Eyre, is 15 m below sea level and is fed by intermittent rivers flowing from the north-east, creating one of the largest areas of internal drainage in the world. Lakes Gardiner, Frome and Torrens are to the south of Lake Eyre.

The total population of South Australia is about 1 500 000. Adelaide, the capital, has approximately 73 per cent of the state's total population. Whyalla and Mount Gambier are the two largest centres outside Adelaide, followed by Port Pirie, Port Augusta and Gawler.

Largest Cities

South Australia enjoys hot dry summers with relatively mild nights and cool winters, with most rainfall occurring during May to August.Adelaide's average daily maximum temperature in January is 29 C, and in July 15 C. South Australia is the driest of the Australian States and Territories. Its average annual rainfall is 528 mm, but just over 80 per cent of the State receives an average of less than 250 mm of rain a year.

Rural Production

Most of South Australia is arid or semi-arid. Only four per cent of the State receives more than 500 mm of rain each year, with only nine per cent of farm and pastoral area under cropping or permanent improved pasture. Despite the harsh climate, the State contributes more than 10 per cent of the gross value of Australian agriculture. Farmers have developed a highly productive agricultural system based largely on the integration of cereal and livestock.

Cereal crops of wheat, barley and oats grown for grain comprise 90 per cent of the area sown to crops. Wheat is the main cereal crop, with average yields of 1.4 tonnes a hectare. South Australia grows about 13 per cent of Australia's wheat and about a third of it's barley, including high-quality malting barley. Most of the oat crop is used for supplementary livestock feed, but a small proportion of high milling quality is grown. Cereal crop yields depend on the adequacy of seasonal rains and can fluctuate dramatically.

About 42 per cent of Australia's vineyards are in South Australia and most of the grapes are used for wine making, with a small proportion used for dried fruit. In 1991-92, 25 800 hectares were planted and 218 083 tonnes of wine were produced. Principal varieties include shiraz, cabernet sauvignon, riesling, chardonnay, grenache, sultana and muscat gordo blanco.

A wide range of temperate vegetable and orchard crops are grown in the Adelaide Hills, the northern Adelaide Plains, the south east and the Riverland. Vegetable crops include potatoes, onions, carrots, tomatoes, cauliflowers and peas. Fruit crops include oranges, peaches, apricots and apples; South Australia is the major apricot-producing region, with most of the crop being dried. A large proportion of Australia's almonds are produced in South Australia while avocados, cherries, pears, plums and prunes, and strawberries are other important crops. A range of other field crops including oilseed and grain legume crops are grown in the south east and northern agricultural districts.

South Australia produces about 11 per cent of the nation's sheep, in all districts except the far north. Merinos account for 90 per cent of the State's total flock of some 17 million and localsheep breeders have developed a large framed type of merino suited to Australia's drier conditions. These South Australian merinos produce an exceptionally heavy fleece, typically 5.1 kg of medium to strong quality wool. Other major sheep breeds include Corriedale and Polwarths, which are dual-purpose breeds for meat and wool production.

Cattle are produced mainly in the Adelaide Hills, the lower south east and far north pastoral districts. Dairying is important in the Adelaide, lower south east and lower Murray districts. South Australia has about 990 000 cattle, or four per cent of the nation's total. Pigs and poultry are also farmed.

Commercial fishing is undertaken along the entire South Australian coastline. In the sheltered waters of the gulfs and west coast bays, operators take prawns or marine scale fish, while in offshore waters southern bluefin tuna and shark are caught. Rock lobster is caught along the more exposed parts of the coast, and abalone is dived for in most areas. A small quantity of freshwater fish is caught in the River Murray and associated lakes.

The most commercially valuable species are rock lobsters and prawns, with tuna, abalone, shark and whiting also making significant contributions. South Australia's commercial fisheries produce was worth more than $133 million in 1991-92.

Minerals

South Australia has a well developed mineral industry and in recent years crude oil and natural gas have surpassed coal and iron ore as the major products. It also has important reserves of industrial minerals. In 1988 production began at Roxby Downs, in the mid north, which holds potentially the world's largest copper and uranium mine, with some gold.

The Cooper Basin in the north-east supplies Adelaide and Sydney with natural gas and is Australia's major on-shore natural gas source. Hydrocarbon liquids are piped from the same area several hundred kilometres to Port Bonython, where they are processed for export and domestic use. Natural gas was discovered near Penola in the south east in 1988. Supplies are probably enough for local use and with further drilling may prove sufficient to supplement Adelaide's needs.

Significant amounts of iron and steel are produced at Whyalla, most of which is exported. More than 180 million tonnes of iron ore have been mined since 1900. South Australia also mines more than two thirds of Australia's opals, from centres such as Coober Pedy and Andamooka.

Manufacturing

Transport

South Australia has more than 95 000 km of roads, of which about 25 000 km are sealed. More than 2400 km are classified as national highways. Railways are operated by the Federal and the State governments. This includes part of the Trans Australia Railway from Kalgoorlie (Western Australia) to Broken Hill (New South Wales); the Tarcoola (South Australia) to Alice Springs (Northern Territory) line; and other lines including the isolated Eyre Peninsula system.

The flag of South Australia is a British Blue Ensign defaced with the state badge. The badge depicts a white-backed piping shrike (magpie) with wings outstretched on a yellow disc.

The coat of arms of South Australia was conferred by Queen Elizabeth II in 1984. It incorporates objects reprenting industry in South Australia. At the base is a scroll with the words 'South Australia'.
