Manufacturing constitutes a modest but still significant component of the Western Australian economy. Petroleum, coal, chemicals, and related products are Western Australia’s principal manufactures, followed by machinery, equipment, and metal products. Industries of somewhat lesser importance include wood and paper production, printing and publishing, food, beverage, and tobacco production, and meat processing. Kwinana, located in the Perth metropolitan region along the shores of Cockburn Sound, is a prominent industrial centre. The area has several heavy industries, including oil, alumina, and nickel refineries, a fertilizer works, a major grain exporting facility, a growing shipbuilding and repair industry, and a naval base on Garden Island, on the opposite side of Cockburn Sound.

Services, labour, and taxation

The service sector is by far the largest component of Western Australia’s economy, employing more than two-thirds of the labour force and providing well in excess of half the state’s income. Within the sector, retail trade, property and business services, and health and community services are dominant.

Women form only a slightly smaller portion of the workforce than do men. However, women’s income continues to be significantly less than that of men in most areas. The state has long had one of the lowest unemployment rates in the country, but unemployment within the indigenous population (although decreasing) has remained relatively high.

Tourism—both international and domestic—has been expanding vigorously in Western Australia. The largest numbers of foreign visitors come from the United Kingdom and Ireland. Many also arrive from Asia, especially from Singapore, Japan, and Malaysia; tourism from New Zealand and the United States also has been increasing. Domestic tourists hail largely from Victoria and New South Wales. Perth and the southwestern region are the most popular destinations for the majority of tourists, although the north also serves a significant domestic market.

Western Australia’s per capita taxation revenue is among the highest in the country. The portion of state income generated from taxes, on the contrary, is among the lowest. Unlike other Australian states, Western Australia derives a major percentage of its tax revenue from mining. Payroll taxes and taxes on the conveyance (transfer) of real estate are also important.

Transportation and telecommunications

The most important mode of transport throughout the state is by road. Except for Perth’s electrified suburban rail system and the purpose-built iron-ore railway lines in the Pilbara, rail transport has generally declined. Many branch lines in the Wheatbelt have closed, contributing to the depopulation of most country towns.

The southwest is most extensively connected to eastern Australia by road, rail, air, and sea, and the state has its own local shipping service. The transcontinental rail link is an important tourist attraction. Intrastate, interstate, and international air transport is increasingly important for both people and goods. The state’s major international airport at Perth offers regular flights to Asia and southern Africa; a second international facility at Port Headland offers more limited service. Numerous regional airports are spread across the state.

Western Australia’s telecommunications infrastructure is expanding rapidly. Although standard telephone (landline) services are generally utilized in larger coastal cities and several inland towns, wireless phone service is much more widespread. Wireless networks cover most of the southwestern region, as well as scattered locations in the state’s interior. Data (Internet) service is also concentrated in the southwest, but government initiatives have been implemented to extend access to more- remote regions.
