Sydney FC fans wanting to attend the A-League grand final in Melbourne on Sunday may have to pay up to five times the face value for tickets, after demand has led to a stream of tickets listed online for auction.

With the A-League's deciding match being played at the 30,000-seat AAMI Park in Melbourne – the smallest venue ever for a grand final – demand for the limited number of tickets has soared as fans snap at the chance to attend by paying a small fortune.

The unavailability of the 53,000-capacity Etihad Stadium in Melbourne means the game will be played at AAMI Park where about 3200 seats have been reserved for travelling Sydney FC supporters.

Just hours after going on sale exclusively to members of both Sydney FC and Melbourne Victory, tickets were listed and sold on auction and trading websites. Some fans have been so desperate to go to the Sky Blue's first grand final in five years, they have paid for a match ticket at twice the amount of return airfares.
