Nine-year-old Archie Hill has been handpicked by Justin Bieber to dance on stage at his Brisbane concert tonight, after nailing a YouTube audition.

He is one of four Queenslanders selected to perform in front of a 45,000-strong crowd at Lang Park.

"I am so excited," Archie told ABC Radio Brisbane.

"I've been listening to his songs since I was three years old.

"I just love him."

Archie, who has been dancing since he was two-and-a-half, learnt the choreography for the concert online and got his mother to film him at his Ashmore dance studio.

They found out after school had finished on Friday that he had been selected.

He said he cried and his mother was speechless.

Archie has not had a chance to tell his classmates, but said he reckoned his teacher would fill them in today on why he was not in class.

'Oh you're the cool guy I saw on the video'

It has been a sleepless two nights for the youngster; he's been preoccupied dreaming of how his meeting with Bieber will go.

"I reckon he will say, 'Oh you're the cool guy I saw on the video, do you want an autograph or photo or something?'

"I'll probably say, 'can you sign my shirt or something?'"

Archie has had his sights set on stardom from a young age.

He is a budding actor who has filmed commercials and he also had a small part on the recent Paul Hogan miniseries.

But it is dancing which he said he would "never want to leave".

"When I'm sad I just start dancing, or when I'm angry, I just love it."

Beliebers camp out for two nights

Bieber flew into Brisbane on Sunday night.

Fans started lining up outside Lang Park on Saturday in order to secure prime mosh pit positions.

Some have paid $600 for VIP tickets.

Leah told ABC Radio Brisbane she had been camping out with her daughter Brooke since 3:00am.

"I think I might be nuts, but it's all for a good cause," she said.

"It was just safer for us to come early.

"I have become a fan now, I know all the song words and all the raps.

"I just know that they'll look back at this and they'll remember this like I remember it. They will always have a chuckle.

"It might be an inconvenience for the day, but it's worth it."
