Again thanks everyone! The reason that my OH gets to choose it that its his house that wed be putting on the market! I have a fab job here and earn above £33,000 as a nurse but due to past credit issues im never going to be able to help him to buy a house here in the UK. We have a new son so will be needing a bigger house here but without my help in this curent climate we'd never be able to afford anything much bigger than we have. Whilst in Oz i have a job lined up on similar money even if my OH only got a part time job to help with our little one, from what i can gather (tell me if im wrong) we should be able to afford to buy something reasonable and much bigger in Adelaide.
Its the overall lifetstyle that i yearn for as i wish that i could somehow transplant into my OH's mind 'life outside of the UK' (hes never really been abroad) i know that in the end he's love it.
