Vulcans visited Australia regularly during the squadron Far East detachments, alternately to either Butterworth or Tengah, for the annual "Moonflower" exercises in the 1960s. Three of the detachment aircraft would position to Darwin for fighter affiliation exercises with the RAAF. If an Aussie Mirage could even get close to, never mind catch, a Vulcan it could handle anything flying in Indonesia - which was where their most likely threat lay at the time.
