Prehaps we'll see Jetstar open days in London, Los Angeles, Vancouver etc, with applicants flown to Sydney for second interviews and a look around. They have advertised locally with little response to satisfy immigration requirements.
Once J* pilots start leaving for jobs in Asia and the Middle East management will have found out how little they can get away with paying and how much pilots are willing to put up with in order to live in Australia.
That is then the basis for conditions based on supply and demand. Once "how much less will they accept to live in BNE/SYD/MEL vs HKG/SIN/DBX" becomes know pay scales will be set accordingly. Unfortunately they are likely to be a fair bit lower than similar jobs overseas.
