It appeared to fly up from RAAF Base Amberley via an inland route overhead Emerald Airport and onwards to Mackay Airport where it was spotted below on finals for Runway 14. It then completed a missed approach and departed to the South.
With the airwork complete, the Globemaster departed Rocky and returned to Amberley.
A41-209 is one of eight C-17A Globemaster III aircraft that are flown by the RAAF's No. 36 Strategic Transport Squadron based out of Amberley.
