The Murray Mallee is the grain-growing and sheep-farming area of South Australia bounded to the north and west by the Murray River (in South Australia, "River Murray"), to the east by the Victorian border, and extending about 50 km south of the Mallee Highway. The main towns in the mallee are Karoonda, Lameroo and Pinnaroo. Towns along the Murray are generally considered to be in the Riverland or Murraylands, rather than the Mallee.
