Hi,
Well I knew the moment I stepped out of the airport and felt the heat, but in fairness I never wanted to come here at all. (my wife wanted to be near her parents)
I've been luck in as much that in the 18 months we have been here I've been able to spend 8 of them back home with work and familly stuff. Most, if not all people will tell you that she'll grow out of it, or she's probably missing her friends but at 38 years old and having spent a lot of time away from home and all I know, whilst travelling and living 300miles from home in the past, I am confident to say that Australia is not for everyone, I hate it here and can't wait to leave again, and have only been back 75.5hrs.
Good luck with whatever you decide.
Ps I believe that Queensland is the worst place we could have ever moved to.
