That is precisely my thinking too, there are a lot unsubstantiated rumors being banded about on here, some people think AU customs are so incredibly intuitive they are impenetrable (which is not the case), others think Aussies are scamming the hell out of vendors (again as a general rule for legit buyers this is not the case and certainly no more than any other nationality), and some think vendors are scamming Aussies using the customs excuse to selectively scam. As with most things I suspect the truth lies somewhere in-between all of these factors and if you add in the LE creating buyers accounts scenario I think you have your answer re a disproportionate amount of AU non arrivals. If vendors were to take each sale on its merits based upon past sales, stats etc then that would put an end to most of this crap, of course there will be seizures, that is inevitable but if the refund/reship terms reflect the factors I mention then it wouldn't be hard to filter out the scammers/LE from the legit buyers.
