The headwaters of the river rise on the western slopes of the Great Dividing Range[2] in the Dunmore State forest and flows in a south westerly direction.

The river continues through the Booroondoo State Forest then crosses the Leichhardt Highway, flows past Currajong and Goodar and then veers west.

It flows through the Wanda Wanda Waterhole then continues south west until discharging into the Barwon River northeast of Mungindi on the border between Queensland and New South Wales.

The rivers have a combined catchment area of 44,600 square kilometres (17,220 sq mi).
