I spoke to AMP and they said that I was unable to touch my super, even though I explained that I would never be coming back. They told me that the government has no way of knowing whether you will or will not return and so it is effectively frozen. My wife's mum works in payroll in a large comapny and confirmed this for me.
Funny how they still manage to tax it though. I wonder if any will be left when i do return?
