They were identified as A34-007 "Kaos 71" and A34-004 "Kaos 72" and both were photographed above as they arrived into Townsville where they are reportedly deploying for an exercise.
UPDATE! On Wednesday 7 June, both A34-007 "Kaos 71" and A34-004 "Kaos 72" flew back down to Amberley from Townville following their exercise. A34-007 flew direct but A34-004 "Kaos 72" again looked to complete airwork again at Dysart Aerodrome.
Sincere thanks to Townsville plane spotter Graham A for allowing us to share his great photos!
