I have an i-tunes a/c in Australia but I have now returned to the UK can I change my e-mail address in my account with my new UK one and carry on as normal?

Hi bpaul1877,

Thanks for visiting Apple Support Communities.

You have a few options available if you have moved to a different country.

You can add your new email address as an alternate "rescue" email, or change your Apple ID to the new email address. I recommend following the steps in these articles if you make either change:

You can also make purchases from the UK iTunes Store by following the steps in this article:

All the best,
