The only takers for this sandwich will be A320 F/O's currently based in NZ. For them it is a payrise and 6 months experience on a new A/C - not to mention the end of 4 sector, early start days.
No A320 guys based in Aus will take it up as it amount to a paycut along with a relocation without any allowances from the company. If they want to fly the A330 the opportunity is already there - based in Aus.
