The AFL Fans Association says more grand final tickets should've been allocated to Collingwood and Brisbane fans.

The MCG seats more than 100,000 people, but the two competing clubs are only allocated 17,000 tickets each for members.

That's despite Collingwood having more than 100,000 members, and Brisbane having in excess of 50,000.

Fans Association President Ron Issko says it's not fair on fans.

"[The ones] that go week in and week out, home... away... interstate, rain hail or shine, and then when it comes to the biggest game of the year, the grand final, some members just can't go."

The Brisbane Lions take on Collingwood at the MCG this Saturday at 2:30pm, with ABC Sport live blogging every moment.
