The Boomi River, an anabranch of the Barwon River and part of the Macintyre catchment within the MurrayâÂÂDarling basin, is located in the northâÂÂwestern slopes region of New South Wales, flowing downstream into the South Downs region of Queensland, Australia.
The river rises about east of Gundabloui, and flows generally northâÂÂeast, joined by five minor tributaries, before reaching its confluence with the Macintyre River, about northâÂÂeast of Boomi. The river descends over its course.
The Boomi River flows past, but not through, the town of Mungindi.
