The Kullili people were an important group who occupied an area of Australia from about Thargomindah in South West Queensland, southward to the Currawinya Lakes, and west to Bulloo Lakes and north to Norley Station.
Breen pointed out that some groups in southwest Queensland had abandoned their original languages (but not their names) and adopted the ‘Wilson River Language’ in the early days of Australian settlement when people moved from Thargomindah to Nockatunga (near the modern town of Noccundra).
