 Calculating from records on the supply of foodstuffs to the native population, in 1852 it is estimated that there were some 70 Ngadjuri people drawing rations, and the children readily joined in the introduced games by playing marbles, rounders and cricket, but the spread of agriculture appears to have coincided with the disappearance of the central community within the following 20 years.The Mimbara group however held out in the northern bushlands until 1905, as the last "wild" group of Aboriginal peoples of South Australia.These were relocated south to the outskirts of Quorn, and at Riverton, and on Willochra Creek.
