Mount Cordeaux is a mountain near Brisbane, Australia and rises 1,135 m. It lies to the immediate north of Cunninghams Gap in the Main Range National Park. It is known to the Aboriginal People as Niamboyoo, however, the meaning is unknown. It appears that early usage on names for the mountain varied, as a 29 September 1897 report in the Warwick Examiner and Times, refers to "the well-known Cunningham's Gap, with its twin sentinel peaks, Coonyinirra and Niamboyoo".

Cunninghams Gap is a pass over the Great Dividing Range between the Darling Downs and the Fassifern Valley in Queensland, Australia. The Gap is the major route over the Main Range along the Great Dividing Range, between Warwick and Brisbane. The Cunningham Highway was built to provide road transport between the two regions.
