Maryborough Airport (IATA: MBH, ICAO: YMYB) is located approximately 3 km (1.9 mi) north of the town centre. It serves as a small regional airport serving Maryborough and nearby townships. However, increasing competition with Hervey Bay Airport has led to a decrease in commercial air traffic. The airport is primarily used by the Maryborough Aero Club, a flight school and (in development) an aviation museum. The airport was used by the Royal Australian Air Force during World War II; the buildings constructed for the RAAF are now listed on the Queensland Heritage Register.
