There has been huge demand for tickets to the 2018 A-League showpiece, with the event set to be held at Newcastle's McDonald Jones Stadium for the first time in the competiton's history.

20,000 tickets were sold within six hours during the member pre-sale period, forcing FFA to shift forward the general public sale times.

However, some ticket-holders appear to be taking advantage of increased demand, with tickets on Ticketmaster's official re-sale site listed for as high as $1,277. 

FFA receives no portion of the increased sales price for tickets sold on Ticketmaster Resale, and FFA's spokesman, John Kent, said the prices were "concerning". 

"FFA has limited ability to control the prices of re-sale tickets and we warn fans against buying them on secondary markets," Kent said. 

"We don't support people selling tickets at increased prices whatsoever, and we caution people against buying these tickets because we can potentially cancel them.

"Our policy is not in favour of people increasing the prices of re-sale tickets. If they have to be re-sold, we strongly encourage fans to sell these tickets at face value."
