Grand Final celebrations turned into a rogue street party in the team's home suburb in Melbourne on Saturday night, with police having to move in to control thousands of revved-up Tigers fans.

One fan took his passion to the extreme as he climbed on the roof of a nearby store on Swan Street and set alight a cardboard sign showing Greater Western Sydney player Toby Greene.

Many fans took to the streets to continue celebrating after watching the Tigers' triumphant win over the Giants at the MCG.

But celebrations quickly turned chaotic with police arresting dozens of fans outside pubs and on streets.

Social media videos quickly circulated showing a number of brawls near the Richmond train station, with police forced to intervene.

Nearby on Church Street, hundreds more revellers flooded the streets, throwing and smashing bottles on the ground.

Rumours that some of the Tigers players could make an appearance in Richmond got fans even more excited, with their loud roars audible from one street over.

Nearby pubs and hotels in Richmond were bursting at the seams, with fans on balconies chanting the Tigers song while celebrating.

Just hours earlier, Emma Smith and her family, who describe themselves as "fourth generation" Richmond fans, were watching the match at the Tigers' home ground at Punt Road Oval.

Emma's kids came dressed like their mother in team colours, blending in with the thousands of fans covered in yellow and black.

"It's one big family here, in one big great spot with magnificent Melbourne sunshine," she said.

In Sydney smaller crowds gathered to watch the game unfold. By the end of the brutal third term, numbers slowly dwindled, with many fans not seeing the entire match through.

Travelling up from Sutherland for the game, Caitlin Goman, 25, and partner Adrian Verzin, 24, knew there was no chance of a comeback and no point in staying to watch the now-inevitable loss.

"We gave it a crack, just couldn't kick a goal unfortunately."

Die-hard Giants fans Peter Murphy and five-year-old son Jack stayed until the end to show their pride for the team.

"I think everyone here in Sydney is really proud of them for what they did.

"There's always next year."
