Former Geelong president Frank Costa has declared GMHBA Stadium should play host to this year's Grand Final if the Cats make it.

With the ability of crowds to attend games this year still in doubt, GMHBA Stadium's inferior capacity wouldn't be an issue should all footy fans be locked out of the game's marquee day.

“That would be fair (to host the Grand Final at GMHBA Stadium),” Costa told the Herald Sun.

“The oval is in superb condition and the stadium is first-class.

“The players are used to that oval – it’s long and narrow and different to some of the Melbourne grounds, so it would have to be an advantage.”

The Cats have long clamoured to host finals in Geelong, with coach Chris Scott declaring the system wrong in the lead-up to last year's finals series.

The logistics of a late Grand Final are still up in the air, with the men's Twenty20 World Cup scheduled to be played in Australia from October 18.

This year's AFL season will almost certainly extend beyond September, with fans still waiting on news of a return to play.
