The Tharrkari, also referred to as the Targari, are an Aboriginal Australian people of the Gascoyne region of Western Australia.
The Tharrkari spoke one of four dialects of Mantharta, the other members of the dialect continuum being the Thiin, Warriyangka and Djiwarli.
[1] 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.
With the advent of white colonization and pressures from coastal development, the Tharrkari are said to have migrated eastwards to the Lyons River.
