if you are worried u will suffer from 'boredom' then maybe being a pilot isnt for you, not that you will get to work for qantas, especially with an attitude like that. If one is lucky enough to pass a selection for that of Qantas then one is very highly unlikely to just get 'bored' of the job.
You really need to get a REAL insight and do your own research as opposed to just searching forums.
