Most of the rich farmland and good ports are in the east and particularly the southeast, except for the area around Perth in Western Australia. Melbourne, Sydney, Brisbane, and Adelaide are the leading industrial and commercial cities. There was considerable industrial development in the last two decades of the 20th cent. While the Australian economy fell into a severe recession in the late 1980s, it experienced an extended period of growth beginning in the 1990s. It then suffered somewhat from the Asian economic slump of the 1990s and from the "Big Dry" drought of the early 21st cent., while also benefiting from increased mineral exports to China during the same period.
Australia is highly industrialized, and manufactured goods account for most of the gross domestic product. Its chief industries include mining, food processing, and the manufacture of industrial and transportation equipment, chemicals, iron and steel, textiles, machinery, and motor vehicles. Australia has valuable mineral resources, including coal, iron, bauxite, copper, tin, gold, silver, uranium, nickel, tungsten, mineral sands, lead, zinc, natural gas, and petroleum; the country is an important producer of opals and diamonds.
The country is self-sufficient in food, and the raising of sheep and cattle and the production of grain have long been staple occupations. Tropical and subtropical produce—citrus fruits, sugarcane, and tropical fruits—are also important, and there are numerous vineyards and dairy and tobacco farms.
Australia maintains a favorable balance of trade. Its chief export commodities are coal, iron ore, gold, meat, wool, alumina, cereals, and machinery and transport equipment. The leading imports are machinery, transportation and telecommunications equipment, computers and office machines, crude oil, and petroleum products. Australia's economic ties with Asia and the Pacific Rim have become increasingly important, with China, Japan, and the United States being its main trading partners.
