Condorito:
If I was an expat I would be flying for QF or LH... No I'm local, but I've done my share of flying overseas,actually I could use some advice myself regarding expat jobs overseas for high time widebody captains. Regarding your question you'll have to spend a little money and time to convert your licence, but nothing too extravagant,but you have to do a couple of hours,and the written.Conditions are O.K. but nothing like flying for a major outfit in Europe, the states or Oz. I'd say money is half what you would make in Oz in the same position, and benefits are third worldish, but overall you are O.k. for the country standard. Nothing wrong with an australian licence, in fact there's someone with your same background that just upgraded to Captain. Roughly six years with the company.
Keep in touch.
