The Automotive industry encompasses each level of the passenger vehicle supply chain, from manufacturing through to wholesaling and retailing. The industry also includes repair and maintenance operators. Local manufacturers have struggled over the past five years due to the high Australian dollar for much of the period, reduced import protections and consumers' shifting preference towards smaller fuel-efficient imported cars. These trends have not been detrimental to all segments of the industry, as sales growth for imported vehicles has enabled wholesalers and some dealers to offset much of the decline from manufacturers. Industry revenue is forecast to grow at a compound annual rate of 1.1% over the five years through 2015-16, to reach $161.9 billion. The industry's steady growth follows a significant decline at the beginning of the period, largely due to the Japanese tsunami in March 2011. The tsunami disrupted the automotive supply chain for parts and vehicles imported from Japan, one of the main motor vehicle importers to Australia. In the current year, industry revenue is forecast to grow by 1.7%, due to a projected rise in consumer sentiment alongside the implementation of free trade agreements with Japan and Korea, which have begun to reduce the cost of imported vehicles from these countries.
