Hi all.
I moved back to the UK Dec 2015 after 5 yrs in Tasmania. It was a hard decision, but I missed family, friends, blah, blah, blah.
Anyway, I got a job back in the UK and settled in fine. I was pleased to be back at first. I saw friends I hadn't seen in years, had food I hadn't had in years, etc. I also explored bits of the UK I'd never been to before like Devon and Cornwall, which I still think are incredibly nice.
Anyway, after just under a year the company I worked for went bust and I had to find a job over the Christmas period which wasn't fun. Like many of the posts above I'm also a dual citizen and it actually caused me several problems. I had to jump through some major hoops at the dole office because they classed me as a foreigner. Several jobs I applied for (I'm a Mechanical Engineer) turned me down because of my dual citizenship saying I could be a security threat! So, please be aware that the dual citizenship can be a problem in the UK. I did consider ditching my Aussie citizenship just to get a job! Anyway, in the end I turned down some decent UK job offers and moved back to Australia. I started at a new job in Melbourne on Monday and I'm pleased to be back.
Everyone is different. Some people prefer the UK, some prefer Oz. Some, like me, see good and bad in both are are split between the two. Do what you've got to do.
