Sounds like you managed to get the out of print North American version that was imported into Australia with the AUS rating on the packaging wrapping plastic thingyagingy.I just got it in the mail today and I dont know which edition it is to be honest It's both region A and B and the DVD is 1, 2 and 4 according to the info sheet. And there is no age restriction thing on the box or the bluray only MA15 on the plastic that I removed
