Hi Jooles
There is quite a bit of info in this link:
What's the cheapest way to ship boxes from Switzerland to Australia?
I hope that helps!
By the way, may I ask what you made you decide to return to the UK? We have been here for a couple of months and the jury is still out. You may well also have seen lots of lively debate about the pros and cons of life both here and in the UK on this site!
Anyway, wishing you all the best in the future!
