Its getting tougher to import from the usa .US customs are checking more and more containers going to Aust ,with cars and bikes ,looking for guns coming into here .If they think there maybe a problem they unpack the container and charge you 2500 us dollars .And now we get charged a customs fee for every part you buy from a different supplier ,eg 2 wheels from one shop is one charge, 6 wheels from another shop another charge ,a part from another shop yep another charge and so on .Something like 125 dollars for each .I know someone that just got charged an extra 1500 dollars for his parts .
