Hi, I'm an Australian citizen, and I'm flying back to Aus next month after a year overseas. I'm going via England, so I'm thinking of picking up a new MacBook duty-free in London before I leave. Problem is that I'll still have my old TiBook with me (I'm going to give it to my mum), so I'll be carrying two laptops with me. Does anyone here have any experience doing this, ideally with Australia, but otherwise in general? Am I going to be slapped with tax or import duty for the second computer? I know some countries have a regulation where people can only carry one computer tax-free for "personal use", but I can't find anything online about the position in Australia. Any help much appreciated.
