The area was also rife with rumours that the Woomera Test Range was to be expanded and that stations including Commonwealth Hill, Bulgunnia, Roxby Downs and Andamooka would lose some of their land, which in turn would reduce their wool clip.
[3] Byron MacLachlan, the leaseholder of Commonwealth Hill in 1947, along with a consortium of pastoralists and lawyers, established a working agreement to ensure the continuation of pastoral activity that would not interfere with the long-range weapons project.
In 1957 the minister of Supply, Howard Beale, spoke with the graziers who could be affected by the trials and announced that the Commonwealth government would pay for the installation of blast-proof shelters.
[5][6] The land on which the station is situated is described as a flat sandy plain on the north-western margin of the Gawler Craton, covered with sand sheets and dunefields.
Low mulga woodlands and tall myall shrublands over perennial grasses dominate with occasional salt lakes and lunette systems.
