CASA has given some woofull dispensations in recent times. Jetstar A330 with no crew rest. They are all ex QF so would have had crew rest I assume. My mates admit that they get really crappy rest sitting with the pax. I know QF A330s signed off on the 4th crew member for a similar deal sitting business with the punters but thats for only 8 months.
QF group does what they want, when they want with our governing body at the moment so this crew member operating the doors number not raising an eye from CASA does not surprise me in the slightest
