Hello
I was in Oz for two lonnnng years too many. I really did not settle. It really was a combination of things. We moved out there as dh wanted to give it a go, I had about a week to decide if I wanted to go, I was about 5 months go with dd2 at the time. We left the Uk when dd2 was 3 months old, and dd1 was 2yo. It was awful as I had to adjust to having next to no support. Dh had hi two dsis' there, who lived a considerable distance from each other. One dsis was not that interested, his other was but has dc of her own, so it was a struggle, especially adjusting to giving two with a dh who was not supportive, and pretty much had the attitude of 'just get on with'. Really fucking helpful 
I gave up my job of 15 years which I bitterly regret, as I loved my job, and they were giving out part time opportunities like candy. I was on ml and they left me alone for that year. I looked into play groups, swimming, gymnastics, and one lady I did gel with hated it in Perth lol, but then left shortly after being there just 5 months.
I think the gods were looking down on me, when after I broke my leg, and was desperate to get back to the Uk as dh was more than fucking useless, he was made redundant from his company. We had a holiday booked in Phuket for before we came back, and we headed home. But omg the relief of actually getting on the plane was exciting, and when we got back, it all fell back into place.
We had rented our house out, and the tenants were happy enough to move out, as they were supposed to be looking for somewhere to buy, but liked our house too much, and were relaxed about it.
We've been back since October and it's been so much better. I have my support network back, we actually go away for weekends, we're not struggling like we were with the expensive rentals. I have my friends back, I'm not sweating and living in flip flops and worrying how much it's gonna cost to go to the doctors for an appointment.
I did return for a holiday in the August of 2012, and I so wished I didn't get on that plane back to Oz, I should have stayed in the Uk. We were only on temporary 457 visas, so Amen to that.
I don't regret coming back, but do regret staying there as long as we did, as I should really have come back to MY job, instead of pandering to his Lordship. As funnily enough, my job would still be there today as my friends are still there, but dh was given the boot, so I had the most stable job. Our marriage has been greatly affected by the move to Oz.
