What pilots get paid in Aussie has SFA to do with what the pilots at Jetconnect get paid.
How their pay and conditions compare to pilots doing similar jobs (Virgin, Air NZ Jetstar etc), in New Zealand is what matters.
You need to be comparing apple with apples. They are New Zealand pilots employed in New Zealand on a New Zealand contract.
I think Aussie pilots need to realise that by and large they get paid better than in most other parts of the world. Good on you for being able to achieve that, but just because you get paid well it doesn't translate that your conditions will automatically flow into other jurisdictions.
One of Ansett New Zealand's downfalls was the generous salary packages they brought with them to New Zealand from Australia.
