The Riverland is a region of South Australia. It covers the area near the Murray River from where it flows into South Australia downstream to Blanchetown. The major town centres are Renmark, Berri, Loxton, Waikerie, Barmera and Monash. Each of these are accompanied by minor townships, the total area comprising approximately 30,000 people. Many of the towns were established for the re-settlement of soldiers after their return from World War I or World War II. Most towns were established as separate irrigation districts.
