Euston belongs to the traditional lands of the Tati Tati Aboriginal people.
At the 2006 census, Euston had a population of 462 people. Until the irrigation development at Robinvale Euston was the main town in the area. A Post Office opened on 1 May 1852. It closed in 1853, then reopened in 1856.
In 1876 the settlement at Euston was described in the following terms:
Euston is a crossing-place for sheep and cattle. There is a Custom-house officer here, though I should judge that his avocations were not of an extremely onerous nature, and the township also possesses a post and telegraph office. If the building can be taken as a type of the township, Euston has not a long life before it. The walls appear as if rent apart by an earthquake. The hotels and about a dozen houses constitute the remainder of the township.
Euston has the Euston Sports and Recreation Club and the Euston Pub.
The town used to field an Australian Rules football team competing in the Millewa Football League, however were forced to merge with Robinvale due to lack of players in part caused by the establishment of Robinvale rugby league club.
