Looking to import Fallout 3? Might not be such a wise idea - at least while the game remains without classification. Australian Gamer decided to get the final word on the legalities by contacting someone at the Australian Customs Service. Here's what it came up with:
...this was also confirmed by the Senior Customs Officer I spoke to, who told me "if they are refused classification they are deemed to be prohibited imports". When I pressed him as to what the repercussions of this would be if you went ahead and tried to import it anyway, he told me "Generally, Customs will seize the goods".
Well, "seize" is better than "fine", which is better than "gaol", which is better than "strip search", etc. The lesson? It's not so much you can't do it, just that you do so at your own risk.
