Straddling the Murray River in north-west Victoria and western New South Wales, the Murray Darling is a vast region. Combined with Swan-Hill immediately to the South-East, it is the third-largest winegrowing region in Australia after the Riverland (South Australia) and Riverina (New South Wales). Although the distance between the eastern and western extremity of the region is in excess of 350 kilometres (217 miles), the climate throughout is virtually identical
It is hot, with long sunshine hours, low humidity and negligible growing season rainfall. The GI is 25,578 km2 in size and has a total of 16,068 hectares of vineyards. The main varieties grown in the region are Chardonnay, Shiraz, and Cabernet Sauvignon.
