My husband and I just arrived from working in Australia, he is a Chef, myself Pastry, and all I can say is be careful. It is not like North America with it's labor laws, we were on sponsorship by our employees, and worked with out sponsorship legally as well, living there for 4 years.
There is a lot of funny business that goes on there, black money is a big problem, sponsorship is a nightmare 90% of the time, and the Australian mentality is much different to what we were used to.
As a Chef my husband has worked in France for several years, in the middle east and in Australia, and for some reason the fact that they are so sheltered from the rest of the world makes them some what narrow minded to the fact that they have the best of everything, which they will remind you daily of. Coming from North America it made me crazy to see them cutting down Americans and their culture, and appoligising to Canadians for assuming they were American!
Don't get me wrong, go on Vacation to Australia, it's a beautiful country, but don't think that it's paradise and it is different to vacation there than it is to live as an immigrant.
So good luck, and if it were me i would consider somewhere a bit more modern, as they are a bit behind the times down there.
