It's exact movements are not fully known but it looks to have flown into Melbourne from Sydney the previous day.
UPDATE! On Monday 16 January, N604AK departed Hamilton Island Airport returning to Melbourne (Tullamarine) Airport.
Also on Thursday 12 January, Henadeck Cessna 525 Citation CJ1 VH-YNE departed Hamilton Island Airport for Bankstown. But it was only 'home' for a short time before it departed Bankstown and returned to Hamo! It is still parked at Hamo. VH-YNE had originally arrived at Hamilton Island Airport on the previous Thursday 5 January.
