In August 1840, the Colonial Land and Emigration Commissioners of the British Government decided to allow the purchase of land anywhere in the Port Phillip District of New South Wales (now in Victoria), Australia.
In its place he purchased land near the present Koroit in western Victoria.
As a consequence, Unwin and Elgar were granted land nearer to the city.
[3] The original location of the special surveys are shown in maps of Port Phillip District by Russell[8] and Hoddle,[9] drawn in 1841.
[10] The Unwin's, Dendy's and especially Elgar's Special Surveys have had a lasting effect on the alignment of Melbourne subdivisions and roads as some boundaries did not conform to the one mile (1.6 km) interval survey Section lines running north–south and east–west referenced from the survey datum at Batman's Hill.
