The Riverina /rɪvəˈriːnə/is an agricultural region of south-western New South Wales, Australia. The Riverina is distinguished from other Australian regions by the combination of flat plains, warm to hot climate and an ample supply of water for irrigation. This combination has allowed the Riverina to develop into one of the most productive and agriculturally diverse areas of Australia. Bordered on the south by the state of Victoria and on the east by the Great Dividing Range, the Riverina covers those areas of New South Wales in the Murray and Murrumbidgee drainage zones to their confluence in the west.
