The root of the problem is that there is no competition for pilot labour. If you had 3-4 other airlines based in Australia at QFs scale you wouldn't be paying for your interview medical that's for sure. As it stands QF basically get to see 99% of the Australian Pilot population at least once so they effectively can do whatever they want. I guess it gives you an insight into what you are up for over the next 30+ years of your working career.
