It appears that the chopper has been operating in the Northern Territory in recent months - both at Darwin and RAAF Base Tindal.
On Friday 13 October, VH-VAA departed Darwin for Tindal, Daly Waters, Macarthur River Mine and Burketown where it spent the night. On Saturday 14 October, VH-VAA departed Burketown for Cloncurry and Hughenden before it flew into Proserpine (Whitsunday Coast) Airport and then Mackay Airport where it also spent the night.
On Sunday 15 October, VH-VAA departed Mackay Airport for The Glen Airfield which is within the Shoalwater Bay Training Area (SWBTA).
With a combined military exercise involving both Australian and Singapore Armed Forces about to kick off within the Shoalwater Bay Training Area, I suspect that "Choppa 82" is heading there to act in a support role for this exercise.
Of interest, VH-VAA is owned by Lloyd Helicopters and operated by CHC Helicopters Australia for the RAAF.
