Back across the border into SW Qld and on to Thargomindah. 
Thargomindah, the first town in Australia (and third in the world after London & Paris apparently!) to produce hydro-electric power for street lighting in the town. They used the water pressure from the town bore from the Great Artesian Basin. 
It is now a small town of approx 250 people on the banks of the Bulloo River.
Still travelling on dirt roads, we left Thargomindah & headed south to the QLD/NSW border and the tiny town of Hungerford and Currawinya National Park.
