Justin Bieber intimate at Sunrise concert in Sydney

KARACHI: Bieber fever well and truly hit Sydney on Tuesday, when thousands of screaming fans packed into a secret intimate location to see heart-throb Justin Bieber performing live.

Cool-ly dressed in a white tee and black bomber jacket, the 18-year-old pop star blew the crowd away at Circular Quay this morning at a special outdoor concert organised by Sunrise.

The atmosphere at the secret location was electric. Winners had travelled from all over Australia for one reason - to see Bieber perform. The room was lit up with purple lights and in the centre was a little stage containing nothing more than two stools.

Bieber kicked things off with 'Die In Your Arms', which got a massive response from the crowd. He quickly followed it up with 'Be Alright', and the crowd pleasing 'Baby'. All the songs were acoustic, which really gave Bieber the chance to show off his voice. After a few more songs, it was all over. Justin finished the set with his smash-hit 'Boyfriend.'

Bieber did what security and police could not during the morning's Sunrise performance - persuade thousands of teenage fans to step back for their own safety.

Presenter David Koch did his best to calm the crowd after several distressed audience members were carried out by staff, but it required Bieber to intervene before they actually listened.

"This is why I love coming to Australia," he said while looking down at the hundreds of iPhones taking pictures of him.

Bieber announced that his Believe tour was coming to Australian shores within the next twelve months leaving fans even more excited to be "Beliebers."
