The river was named Mooni by explorer and surveyor Thomas Mitchell on 9 November 1846 but the origins of the name are unknown. In New South Wales, the river is officially known as Mooni River, but common usage uses the same spelling as in Queensland where most of the river is located. The sign erected by Walgett Shire Council at Gundablouie Bridge on Gundabloui Road also uses the common spelling Moonie River.
Course and features
The rivers rises south west of Dalby, near Braemar State Forest, south-east of Tara in Queensland, and flows generally to the south-west, joined by thirteen minor tributaries, before reaching its confluence with the Barwon River, before Mogil Mogil farm, north of the village of Collarenebri, New South Wales; descending 198 metres (650 ft) over its 542-kilometre (337 mi) course. The catchment area has no major towns and is extremely flat. The Moonie River is impounded by Thallon Weir, with a capacity of 185 megalitres (6.5×106 cu ft).
The river flows through the towns of the Nindigully, Flinton and just to the west of Thallon. Both the Moonie Highway and Carnarvon Highway cross the river. In New South Wales, only one public road crosses the river : Gundabloui Road crosses the river near Goondoobluie farm in Collarenbri, about 50 km north of the village.
