Based on review of developing history and current situation of Australian wine industry briefly, driving factors of Australian wine industry have been analyzed in this paper. The authors think that the development of Australian wine industry is a result of many participators, multifactor cooperative effect. (1) The grape growers choose the suitable wine grape varieties according to the ecological conditions, and offer high-quality production materials for wineries. (2) Wine enterprises produce high-quality wines according to consumers' different demands, and set up distributions to sell wine products to the consumers at home and abroad. (3) The Australia government supplied governmental subsidies to the grape growers, in order to make the grape and wine industry development sustainable; setting up tourism committee to instruct wine tourism in different wine regions; establishing governmental organization to instruct wine production and administrate international wine trade business. (4) The scientific research institutions accept governmental investment, launch the research works independently, and supply technical services for wine enterprises. Such interior and exterior driving factors combine closely, act cooperatively, and engender a good scene of Australian wine industry.
