Unfortunately that is the easy part. Only way is a work visa and they are very difficult to get. My wife lived there for 10 years in the 90's and has been trying ever sense to move back so we just go visit. Awesome place and people.I am to the point of begging my wife and kids to move to Australia.
Tough sale for a 10 year old a 12 year old with a LOT of friends!
And for the wife who has been working at the same place for 20 years.
