Justin Bieber has infuriated fans in Australia again by leaving the audience waiting nearly 90 minutes at his show in Melbourne on Monday (02Dec13). The Baby hitmaker took to the stage at the city's Rod Laver Arena at 9.40pm (local time), 70 minutes late, prompting criticism from gig-goers and the parents of young fans who were kept out on a school night as the show ran over schedule. Bieber's tardiness also infuriated concert reviewers, with Cameron Adams of the Herald Sun, writing, "Bieber was 70 minutes late coming on stage at Rod Laver Arena last night. In case he has failed to notice 95 per cent of his audience are schoolkids. Finally gracing fans with your presence at 9:40pm on a Monday, meaning your show finishes at 11pm on a school night is just plain disrespectful and ignorant." The incident comes just days after Bieber pulled a similar stunt in Sydney on Friday night (29Nov13), when he showed up around 40 minutes late, while reports suggest he also reportedly failed to start his recent Brisbane concert on time. Bieber's bad boy antics have been a regular in the headlines during his current tour Down Under after he was previously caught spray-painting the wall of a hotel where he was staying on the Gold Coast, prompting a furious response from the local mayor who ordered the singer to clean up the mess.
