i read this post & some of your others & you remind me of me. i happily moved to oz but didnt settle. i was miserable & made everyone around me miserable to. went back to uk but didnt settle & felt like a total failure. realised i spent my time in oz looking for faults instead of enjoying the differences.
back in oz now & happy as. only difference is my attitude. good luck whatever you do but dont be surprised when you realise the problem is you & not oz or the uk.
