HI'er
I agree with your comments re Geoff Dixon. There are quite a few guys in QF security who are very embarrassed about their inability to provide assistance to Schappelle Corby. They are aware of the transportation of drugs via baggage handlers but at the time they had no surveillance cameras in position to record any evidence. The only information that they had was "hearsay" which could not be used in court.
The DJ crew may have volunteered for the flight to Phuket because of the short notice but I understand that the flight (like most of the QF flights for the tsunami) were Federal government charters.
