The Kullilli language region spans Channel Country in South West Queensland, encompassing the township of Thargomindah and areas of the Bulloo, Paroo, and Quilpie Shires. The town was first settled in the 1860s at a crossing of the Bulloo River. The town takes its name from the parish, which in turn was named after the Thargomindah pastoral run, which is an Aboriginal word meaning echidna. A post office was established in 1870 and a telegraph line connected the town to Cunnamulla in 1881. Thargomindah Provisional School opened on 1 April 1884. In 1892 it became Thargomindah State School. The 1890s saw the town prosper as the service and administrative centre of a pastoral district. An extension of the Western railway line to the town was planned for many years; however it never eventuated. The railway did reach Cunnamulla in 1898 and Quilpie in 1917. Thargomindah was one of the first towns in Australia to produce hydroelectric power from 1898 until 1951.

The generator was taken from a unit powered by a steam engine and purchased by the Bulloo Divisional Board becoming the first municipality owned power plant. After that power was supplied by diesel generators until 1988, when the town was connected to the state power grid via Cunnamulla. The power station is still operating with a daily opening to the public. St Edmund's Anglican Church at 60 Dowling Street () was dedicated on 22
