Lip-synching did not cut it for some Perth fans who walked out on Britney Spears only three songs into her first Australian concert at the Burswood Dome on Friday night.

Disappointed fans stormed out of the arena complaining they had parted with hundreds of dollars for their tickets to the circus-themed show.

One female fan outside the arena said it was cheap act.

"People are paying for it and have come here so she should sing," a fan told the Nine Network.

"It was just really bad," Kathy Wright, 32, told Perth's Sunday Times.

"She has not spoken. There is no interaction."

But others among the 17,000 who saw Spears felt differently.

"We're not here to see her sing. We want to see her dance," another fan said.

Burswood Entertainment Complex said record crowds turned out for the concert.

"From Burswood's perspective, the event was a huge success," a spokesman said.

"Early media reports that hundreds of fans left the concert early cannot be substantiated, and Burswood has received no complaints about the concert."

Spears is performing again at the Burswood Arena tonight before making her way to Melbourne on Wednesday for the first of three sold-out shows.
