At 20 years of age, Thomas Hardy arrived in South Australia after sailing from the English county of Devon in 1850. Hardy then spent the next three years working at Reynella Farm, mining for gold in the Victorian goldfields, and driving cattle. Hardy used the money he had earned to purchase a property on the banks of the River Torrens, which he named 'Bankside'.

Vines were planted on the Bankside property and as soon as they were able to bear fruit, wine making commenced.

Hardy steadily expanded the company over the years, purchasing a bottling plant at Mile End, champagne cellars on Currie Street in Adelaide, a disused flour mill in McLaren Vale, and established extensive vineyards in the Pathway area in 1968. In 1976, Thomas Hardy & Sons made its first corporate acquisition by purchasing the London-based Emu Wine Company, which included Houghton, Western Australia's largest winery, and Morphett Vale. The company purchased Chateau Reynella in 1982, where Thomas Hardy had commenced employment some 130 years before, and converted it to its headquarters.

Further expansion came in 1992, when Thomas Hardy & Sons merged with Berri Renmano Limited to form at the time Australia's second largest wine group, BRL Hardy Limited. In 2003, the brands of BRL Hardy and those of Constellation Brands were merged to create the world's largest international wine business. As a result of this merger BRL Hardy Limited was renamed the Hardy Wine Company. In 2006 Constellation Brands acquired Vincor International, adding the West Australian brands of Amberley and Goundrey to the Hardy portfolio.

On March 31, 2008, The Hardy Wine Company changed its name to Constellation Wines Australia.
