THE AFL has pledged there will be no repeat of the crowd trouble that marred last Friday night's Fremantle-Hawthorn preliminary final at Saturday's MCG Grand Final.

A man was banned from football at Domain Stadium after he struck a female patron during the Hawks' win, and the AFL has confirmed a similar incident would attract lifetime bans from the MCG.

AFL clubs and operations manager Travis Auld said there would be zero tolerance for offenders who instigated poor behaviour this weekend.

"We were really disappointed with what we saw on Friday night and we made that clear when it became known to us on Saturday morning," Auld said. 

"That patron certainly won't be welcomed back to football again. 

"It was unacceptable, and we're really proud with the way the industry dealt with it.

"That behaviour is simply not tolerated. It's the same message at any event we hold around the country."

Auld said the woman at the centre of the Domain Stadium incident had attended Saturday night's West Coast-North Melbourne preliminary with her family as guests of the AFL.

More than 200 police will be involved in Grand Final day, along with the ground's security staff, and booze buses will be stationed around the MCG after the game.

There will be reduced car parking due to the Foxtel Footy Festival and Toyota AFL Grand Final Live Site in Yarra Park, so fans are urged to take public transport.

Melbourne's free tram zone has been extended to the MCG for four days from Wednesday.

There will also be a presence of plainclothes police officers to help crack down on ticket scalpers.

Victoria Police Assistant Commissioner Stephen Leane also said there could be delays in getting into the ground as strict security measures were employed at the gates.

"We'll be helping you get in safely to the venue," he said.

"We ask that patrons be a little bit patient – we do have to understand the security arrangements and times we're in, and it will take a little bit of time to get people through the gates.

"We're doing that to make sure people are safe and the event runs smoothly and as safely as it can.

"You will see more police and security as you arrive and as you approach the MCG you'll be asked to undertake bag searches."

Leane said police would have a no-tolerance policy on crowd behaviour.

"We have one single message; if you're coming to the ground and you plan on enjoying the event and you behave in a way that affects others and most particularly affects any of the players or officials on the ground, that will be the end of your experience then and there.

"We'll take appropriate action."
