I don't think ANYONE with any sort of exposure/understanding of the lowcost model/philosophy would be surprised to learn what you've said.
What does amaze me however is the level of ignorance and misguided morality when it comes to the subject of remuneration.
There are literally scores of expats here in the UK, Europe, and the sandpit with big-bus and minibus time who will view this for precisely what it is...a means to an end.
For some that means bringing the family home, for some it means familiarity, for some it means escaping the UK winter, for some it means a potential position after being laid off, for all the money is part of the equation...but I would politely suggest that it would only comprise around 25% of the decision making process.
Jetstar NZ can fish all they want, (its a well worn process understood by many) but until they put some meat on the bones....few if any experienced people will do anything other than express some interest.
