 The first European explorer in the Riverina was John Oxley in 1817 following the Lachlan River to what is now the town of <unk> . Oxley was followed by Charles Sturt , who followed the Murrumbidgee downstream to Lake Alexandrina in South Australia between 1828 – 1831 and Major Thomas Mitchell in 1836 on his way to the Wimmera and the Western District .
