Wollongong's Brad Meier and his mate Werner Bissett were at the front of the queue after making camp at 9pm on Thursday.

"We were freezing, it's so cold," Mr Meier said.

The pair said they could not miss Britney's first tour of Australia and were hoping to buy the most expensive tickets - at $199 - to her Sydney show.

To keep their spirits up through the night, Mr Meier said those in the queue sang Britney songs.

"At the moment my favourite (song) is probably Circus and If You Seek Amy as well," he said.

As for all the gossip and controversy that has surrounded the superstar mum in recent years, Mr Meier is loyal.

"I don't believe any of it," he said.

"But it's always good to read it."
