The Tharrkari's traditional lands were calculated by Norman Tindale to have covered from 3,200 square miles (8,300 km2), including the coastal plain south of the Lyndon River and Lyndon Station, to west of Round Hill, and running east as far as Hill Springs and the headwaters of the Minilya River. Their southern boundary was around Middalya, Moogooree, and the Kennedy Range.[2] Their eastern border was with the Wariangga and the Malgaru.
History of contact
With the advent of white colonization and pressures from coastal development, the Tharrkari are said to have migrated eastwards to the Lyons River.[2]
