The Mungana Affair involved the selling of some mining properties in the Chillagoe-Mungana districts of northern Queensland, Australia to the Queensland government, at a grossly inflated price. In 1929 a Royal Commission was held into the affair and found that two prominent politicians: Ted Theodore Premier of Queensland (1919–1925) and William McCormack Premier of Queensland (1925–1929) each secretly held 25% ownership of the properties sold.
