Sham contracting is illegal.
Paying less than award is illegal.
If your mates are happy to put up with this to get ahead in their career, what else are they willing to do that's illegal?
Getting paid an "apprentice" wage while you are young and learning the ropes is normal. The world doesn't owe you $100k. And if you paid for all your own endorsements and flogged your guts out in GA and never got anywhere, maybe its cos you're a cockhead.
