Thanks Damien, that makes sense. I attended the Mining Expo in Mackay and Tony Abbott was a guest at the Expo on Tuesday, which is when I spotted SWO at Mackay Airport.

When I went to the airport Wednesday morning to pick up another of my fellow colleagues, also from Melbourne, SWO was gone.

The plane was parked up at DPO when I arrived at 12:40 pm yesterday with APU running and looking ready to board and depart. This is the first jet I have seen at DPO.
