if it is really done by your 99, very surprise she is so 神通廣大!!! Do you think she is acquainted with any of your neighbors? Not likely that she can fly herself to Aussie in such short period of time...even if she sends her friend to do such silly thing, she will have to pass the fob to those 36...
But like all the jm say, it would be way better if you can stay with ur friend or even staying in hotel. Just in case...
