Please be aware that there is a (very) long history of embittered QF staff hijacking existing PPRuNe threads to disseminate hate filled tirades against their employer. Nobody knows how justified their cause may be, and nobody has cared for a very long time: If you wish to read this kind of stuff, the Dunnunda forums on PPruNe are full of it - a long-standing billboard representing everything that is the worst about Australia and QF and showcasing none of the features that are attractive.
For those of you considering a new career in aviation in Australia, make your own decisions, but do try and think carefully first. In many cases, advice that you receive from existing staff may be tainted, or addressing a hidden agenda: Normally the moderators will delete obviously tainted posts, or just move them to the Dunnunda forums.
