GM Holden Ltd is an Australian automaker based in Port Melbourne, Victoria. The company was founded in 1856 as a saddlery business, but later moved into the automotive field, becoming a subsidiary of General Motors (GM) in 1931. Holden has taken charge of vehicle operations for GM in Australasia and, on behalf of GM, holds partial ownership of GM Daewoo in South Korea. Over the years, Holden has offered a broad range of locally produced vehicles, supplemented by imported GM models. In the past, Holden has offered badge engineered Chevrolet, Isuzu, Nissan, Suzuki, Toyota, and Vauxhall Motors models in sharing arrangements, with Daewoo, Opel and Isuzu-sourced models sold currently. Holden bodyworks are manufactured at Elizabeth, South Australia, and engines are produced at the Fishermens Bend plant in Port Melbourne, Victoria. Historically, production or assembly plants were operated in all mainland states of Australia: Acacia Ridge, Queensland; Dandenong, Victoria; Mosman Park, Western Australia; Pagewood, New South Wales; and Woodville, South Australia. Until 1990, GM's New Zealand subsidiary Holden New Zealand operated a plant based in Trentham, with a plant in Petone running until 1984. The consolidation of car production at Elizabeth was completed in 1988, but some assembly operations continued at Dandenong until 1996. Although Holden's involvement in exports has fluctuated since the 1950s, the declining sales of large cars in Australia has led the company to look to international markets to increase profitability; in 2006, exports alone accounted for almost AU$1.3 billion in earnings.
