Formed by the confluence of the Lindsay and Grahams creeks, the Tooloom Creek rises about 1.5 kilometres (0.93 mi) northwest of Woodenbong. The river flows generally south southwest through the Tooloom and Yabbra national parks, joined by two tributaries including Beaury Creek, before reaching its confluence with the Clarence River about 11 kilometres (6.8 mi) southeast of the locality of Rivertree Peak. The river descends 202 metres (663 ft) over its 68 kilometres (42 mi) course.[2]
