Course and features
The river rises about 15 kilometres (9.3 mi) east of Gundabloui, and flows generally north–east, joined by five minor tributaries, before reaching its confluence with the Macintyre River, about 12 kilometres (7.5 mi) north–east of Boomi. The river descends 40 metres (130 ft) over its 231-kilometre (144 mi) course.
The Boomi River flows past, but not through, the town of Mungindi.
