Justin Bieber fans in Australia are just as crazy as the ones here in the U.S.

A performance scheduled for Monday morning (time zones, people!) on Sydney Harbor had to be cancelled over concerns for the safety of the fans. Fans had been camped out since Sunday night to see his only scheduled performance in Australia.
