The area of the Riverina region is not fixed, but it usually includes the farming and pastoral areas of New South Wales, west of the Great Dividing Range and in the drainage basin of the snow-fed Murray and Murrumbidgee Rivers. The north edge of the Riverina is the Lachlan River catchment area known as the Central West. Along the Murray to the south, the Riverina border is the state of Victoria. West of where the Murray and Murrumbidgee meet, is the beginning of the drier Far West region.
