The Wholesale trade industry contributes approximately 5% to Australia's GDP. The industry consists of Basic material wholesaling, Machinery and motor vehicle wholesaling, which includes computer wholesaling, and Personal and household good wholesaling. In 2004-05 the largest subdivision was Machinery and motor vehicle wholesaling, which contributed around 41% to the industry's value added, followed by Personal and household goods wholesaling contributing 37% and Basic material wholesaling contributing 22%. The 1990s saw strong growth in industry value added. This increase in value added came from substantial rationalisation within the industry, a wider uptake of technology amongst firms, and the increased use of new inventory management techniques, such as 'just-in-time' processing (Johnson et al 2000).
