Sorry, I side with Wraper on this. If you expect everything on the net to be true, and didn't do at least SOME due diligence, then seriously, get off the net :-)
If the item worked as stated, and was reasonably well made, you got a bargain -which is what you asked for. AND IF, it failed after a while, and was too expensive
to repair, or return for warranty, YOU took the risk. Did the seller explicitly say "Australian warranty" ?
I often buy from overseas - taobao, alibaba etc and spend a heck of a lot of time checking out sellers / feedback etc. I often don't proceed with a purchase.
FYI, most the electrical stuff coming into Aus isn't approved, even some from larger Aus stores. Due diligence. Like I said, stay off the net, people lie there :-)
EDIT: The listing showed up the same time I posted - so I modify my comments a bit. The above does apply in many cases, but this is one definitely a fraud. Sorry
