Scalpers looking to cash in on West Coast's biggest home game of the year have flooded websites with hundreds of tickets.
While only a handful of restricted viewing seats are still available through Ticketmaster for Sunday's elimination final against North Melbourne, more than 500 tickets were for sale on websites such as eBay and Gumtree yesterday.
Many were at more than double their face value.
One seller on eBay offered a pair of gold reserved seats for $499 and a pair of platinum reserve tickets for $599. The original prices were $156 and $170.
Another seller apparently defied Ticketmaster's limit of eight tickets per transaction, offering more than 50 across five different sections of the stadium.
Scalping tickets is not illegal in WA but onselling the tickets for profit is a breach of the terms and conditions attached to the ticket sale by Ticketmaster and the AFL.
The league, which works with websites such as eBay to prevent scalping, warned that tickets bought from unauthorised sellers could be cancelled.
"There's a chance the ticket won't be valid and you'll be denied entry," AFL spokesman Patrick Keane said.
"We try to work with these websites but, where there's no legislation, there's not much you can do."
West Coast spokesman Gary Stocks said scalping was immoral and a problem the club was determined to stamp out.
"We find it a selfish and abhorrent practice," he said. "In the past we've cancelled tickets that we knew were illegally onsold and we'll keep doing it.
"People purchasing these tickets could be in for a big let-down."
Commerce Minister Simon O'Brien said that though he did not like the practice, the Government had no plans to introduce anti-scalping laws.
It is illegal in Queensland and Victoria to profit on tickets to "declared events".
"I would strongly suggest that no one considers buying tickets for events other than through the official channels," Mr O'Brien said.
Consumer Protection Commissioner Anne Driscoll said the cost to event promoters of enforcing anti-scalping measures could make tickets more expensive.
"Promoters can limit the number of tickets per transaction but, as we've seen today, people can find a way around that," she said.
"My recommendation is don't buy these tickets. They might not be genuine and by buying them, we're encouraging scalpers."
