Jangga, also known as Yangga, is a language of
Central Queensland. The Jangga language region includes the landscape within the local government boundaries of the
Etheridge Shire Council. Originally known as Finnigan's Camp after the prospector who discovered gold nearby in 1871, within a year the settlement had become Charleston township, and it continued to grow despite near desertion when its inhabitants rushed to the
Palmer River Goldfield in 1874 and to the
Hodgkinson in 1876. Charleston Post Office opened on 1 February 1876, was renamed Charleston West in 1910 and closed in 1915. After a slump in the mid-1880s the township was again a flourishing centre by the mid-1890s, having five hotels, a school and a court of petty sessions. Charleston Provisional School opened on 4 March 1895. On 1 January 1909 it became Charleston State School. In 1920 it was renamed Forsayth State School. By the late 1890s base metal prices were high: a number of promising copper deposits were opened up in the Etheridge district at Charleston,
Einasleigh and Ortona, and several were acquired by a subsidiary of the
Chillagoe Company. This led the company to commence a rail link in 1907 from
Almaden to Einasleigh and the Charleston area, which was completed in January 1910. The
Etheridge Railway terminated at a new settlement on the other side of the Delaney River. First known as New Charleston, it was renamed Forsayth after the railways commissioner,
James Forsyth Thallon. During the year, all the buildings in Charleston, including the police station and the school, which had previously been at
Gilberton, were moved across the Delaney River to Forsayth. The second Charleston Post Office opened here by April 1910 and was renamed Forsayth in December 1910. On 1 December 1914, it became Wirra Wirra State School. It closed circa 1918. It was on a land parcel on Wirra Wirra Road near the Wirra Wirra railway station ().
Queensland Railways took the railway line over in 1918. Forsayth remained the railhead for transport to the west, although plans in the 1930s to extend the railway to connect to the
Normanton-Croydon railway did not proceed. From the 1980s, renewed mining activity in the area and increased livestock traffic revived the town. The Cobbold Gorge Nature Reserve was established in 2009. == Demographics ==
