Just received an email from M&S (as I'm a regular customer..lol) that they have got a New Website for OZ. It is in Oz dollars and you can still return goods by paying a local address amount within Oz and they will pick up the difference.
I'm ploughing my way through the Oz sight as we speak. I am a regular purchaser via UK and always take advantage of their free delivery to OZ...
Thought this may be useful info for some people
