Hi Chopperpug. It's fine to do the the first year at a learners rate, but your now 4 years in to it and your boss is shafting you while he makes plenty from your effort. There will always be someone willing to work for less, but a lot of the contracts will require an experienced pilot who should be at least getting the award. Your not doing yourself, or any other pilots a favour by now working for $25,000 AUD before tax.
If your working 72 hours duty a week then your employer needs to hire more pilots (give another bloke a start in the industry) If it's not viable for him to do that, then maybe the only reason he's getting work is because of low rates, and or paying his pilots peanuts.
I do understand the Oz scene a little bit.
