Retail trade is one of the larger industries in Australia, contributing around 7% to GDP. The industry comprises Food retailing, Personal and household goods retailing and Motor vehicle retailing and services. In 2004-05 Personal and household goods retailing was the largest contributor in terms of value added at 47%, followed by Food retailing at 31% and Motor vehicle retailing at 22%. Retail trade is a labour intensive industry, and the average labour income share of 75% reflects this. The link between the deregulation of shopping hours and measured hours worked is one of the key issues affecting productivity in this industry.
