Soon I reach The Head, so called because it is start of the Condamine River headwaters, and very beginning of the mighty river system catchment that eventually becomes the Murray-Darling. Rain falling in this valley eventually flows to the Southern Ocean via NSW and South Australia, making it a significant area given role of that river system in opening up of Australia’s interior, and its continuing use for agriculture. The river and the road following it slice through foothills of the Main Range, forming a beautiful gap called Cambanoora Gorge.
