Thanks for the replies, some really good advice there. I appreciate it. Ill try and reply to various points different people have made.
Im an Air Traffic Controller, so my options are extremely limited when it comes to employment in Australia. All ATC is supplied by Air Services Australia. So if they have an international intake then you have a chance, if they aren't recruiting well you ain't getting in. There is no other way. I'm not sure whether the occupation is on the SOL or CSOL, but I know they are not currently recruiting. I've heard it is reopening next year, but after that, who knows.
Thats sort of the issue, I don't know how long the door will be open to me to emigrate on a 457. If I wait 5 years I could potentially put us in a position where it is impossible to go. There's been a shortage in recent years but that won't last forever. To put it into perspective there are around 1000 controllers in the whole of Australia.
Ive said to my Fiancée we will holiday in WA every year but that isn't enough anymore, she wants to be with the rest of her family all year round not just for a month. As I say we have recently spent a month there and I did have moments which were almost surreal, things you just wouldn't see anywhere else where I thought 'yer I could live here'. But then I also had a lot where I thought 'there's no way I could live here'.
Oh and psychologist, really!?
