European influx appears to have started during construction of the Overland Telegraph line from Adelaide to Darwin: in 1870, workers first crossed a creek that was notable for the pine trees that grew on its banks. In 1871, workers with Darwent & Dalwood digging holes for the telegraph line found gold, triggering another Australian gold rush.[note 1] The town grew rapidly with the influx of miners, many of whom were Singaporean Chinese immigrants brought into the Territory from 1874 as a source of cheap labour.[5] By 1873, a telegraph repeater station and police camp had been established.
