AU is a good place to live, but it is expensive when compared to the rest of the world unfortunately
. Plus the government has royally screwed our internet structure and stuff. The healthcare system here though supportive at times is VERY difficult to navigate and is currently going through a reform which may or may-not improve the situation (I think it's going to end up similar to what England has?).
I do often hear good things about Scandinavian countries as well, it might be worth a look - though I hope such a drastic change of environment can be avoided, if possible.
