After an hour on the ground, VH-TOX departed Mackay Airport and indeed continued to Townsville again as TFX6.
VH-TOX then departed Townsville and 'diverted' back into Mackay Airport. This time it was flying as TFX5. It later continued South to Brisbane.
The exact reason for the 'diversions' is unclear but it appears that no 'usual' Toll Freight Metro aircraft arrived into Mackay Airport early on Tuesday 5 November so the visit may well have been planned.
VH-TOX did something similar in the middle of October - as shown above!
