WESTERN Australian Premier Colin Barnett is rejecting calls for a crackdown on scalpers, as tickets for this week's preliminary finals are being found online online at inflated prices. 

Both Friday and Saturday night's games at the 43,000-capacity Domain Stadium are already effectively sellouts. 

Within hours of tickets going on sale, they began to appear on the internet at inflated prices. 

But the Liberal premier has rejected calls for government intervention. 

"I don't think it needs specific laws, I think it's a matter (for) ticketing bodies to administer it carefully, and I think technology allows them to do that in a better way," Mr Barnett told AFL.com.au.

"The AFL I think has done a good job in reducing scalping. 

"You're always going to get people maybe selling off a ticket, but I think professional scalpers are gone."

Labor opposition leader Mark McGowan is calling for Victorian-style legislation, which imposes big fines on those caught scalping tickets at inflated prices. 

Finals ticketing has nothing to do with the clubs, but they get caught in the crossfire from angry fans.

"I'm happy with the process that's been in place," Fremantle chief executive Steve Rosich told AFL.com.au. 

"This is an AFL event and it's run smoothly - our members had the right to access tickets first and they did that in great numbers. 

"It is what it is, it's a sought-after event, a full sellout crowd expected and that comes with the territory."

Adding to the complications is a new Ticketmaster resale system, which allows tickets re-sold through official channels, but at higher prices thanks largely to associated fees.

Rosich said the system, which is common practice in America, was in its infancy.

"We'll wait and see in the cold light of day how that works this year and we'll consider that in due course," he said. 

"But it's not a major issue."

The AFL says any unsold tickets, which come back into the ticket system from corporate or club on-sellers, will be made available at 12pm WST on Thursday. 

There are some restricted view tickets for the Fremantle-Hawthorn game available at face value, but the West Coast-North Melbourne contest is a complete sellout. 

Western Australian footy fans will get some relief from ticketing woes when Perth's new 60,000-seat stadium opens at Burswood in time for the 2018 AFL season.
