But we're talking about Alliance, not Qantas. Considering most of their operation is in Aus, the cost of accommodation and per diem's putting them up whilst spending most of their time in Aus would quickly chew up any savings in reduced pay.
So my question is, if you are based in Aus, but working for a company that's AOC is in New Zealand, I would assume you would still need to be paid IAW Aus IR.
