The 43rd Engineer General Services Regiment, US Corps of Engineers started to construct Manbullo airfield in April 1942. They had gravelled 915meters of the eventual 1,981 meter long runway by 19 May 1942. The Allied Works Council (AWC) then bitumened the runways and taxiways.

On 22 March 1942, nine Mitsubishi G4M1 "Betty" bombers of the Japanese Navy's Tokao Kokutai, 23rd Koku Sentai appeared over Katherine at 12.20pm and circled the area. They then disappeared. A local eyewitness Dorothy Hall said the came back about a quarter of an hour late and dropped their bombs. Local farmer Bert Nixon saw the nine bombers in formation coming in from the north east. Most of the bombs dropped on the Katherine airfield and nearby areas but two  bombs landed near Manbullo airfield
