Yeah Capt Wally and machrider provided fantastic info, should be all you need to know.
I am surprised that someone who has been flying as long as you doesn't have any idea what QF drivers get paid. Obviously it's not "for free".
Go to
www.ppjn.com and all the payscales are there for you, plus for most other airlines.
However, if you are trying to determine your lifestyle before committing to QF wouldn't you want to know the "conditions" not just the "terms"?
Anyway, off to ride my high horse.
