In 1847 the New South Wales Government asked Leslie to select a site for a town on Canning Downs station. It was to be known as Canningtown, the local Aborigines knew the area as Gooragooby, but the name Warwick was eventually chosen. At the first land sale in Warwick 1848 Patrick Leslie bought the first allotment. Today much of the water supply for city of Warwick is drawn from Leslie Dam, and larger than life granite sculptures of and Patrick and Catherine Leslie are located in a park adjacent to the dam wall.
