DHM 24,935 per month salary, which is AUD$9074 per month or AUD$109,000 pa.
If you attempted to
"commute" on this contract, you would still be an Australian resident for tax purposes too. After tax, you'd be clearing about the same as a Dash 8 pilot when you include their usual allowances. This is also far less than an FO on the A320 for Australia's LCC.
What a bogus offer. It's like they didn't even try.
