On Wednesday 25 March, VH-TFQ was then noted operating a nearly five-hour flight out of Mackay Airport out to sea and back. It is possible that VH-TFQ was involved with an aerial survey of the Great Barrier Reef as has happened on previous occasions - such as in 2017 when the photo above was taken.
On Thursday 26 March, VH-TFQ flew into Gladstone Airport and then back to Mackay Airport.
At the time of writing, VH-TFQ is due to return North to Townsville and then Cairns from Mackay Airport on Friday 27 March.
During its visit to the Sugar City, VH-TFQ was using the flight number and callsign of 'HND411' / "Hinterland 411".
