I do not know much about QP, but once you have your offer you can repost with the details, and we can comment on whether or not it is a good one.

Things you need consider in the offer beyond salary if you are planning to bring your family with you--school fees and places for your children (expensive and not always easy to secure in the best schools), private health coverage (the state system is OK but overstretched), housing (either provided or an allowance that will allow you to secure your own decent place), cars are expensive here. If you are not offered these perks as separate items, you need to make sure your salary is high enough to allow for them.

Also if you do a search on QL, there are loads of threads on costs of decent housing, schools, etc.

Good luck.
