MELBOURNE chief executive Gary Pert has revealed the extent of the premier's looming financial boon after selling two years' worth of merchandise in the hours that followed Saturday's Toyota AFL Grand Final.

And the club has promised to celebrate its flag again as soon as possible with Victorian supporters after thousands of Perth-based fans turned out on Sunday to welcome their heroes in the Demons' adopted finals city.

Melbourne set a record membership in 2021 of 53,706 and that is expected to skyrocket on the back of the club's success and the hope it will return home next season.

Richmond's membership grew from 73,515 in 2017 to over 100,000 in July the following year on the back of its drought-breaking premiership, while the Western Bulldogs also smashed their membership record on the back of the 2016 flag.

"I would see us really going through the roof in membership," Demons chief executive Pert said on Sunday.   

"Even since the game last night, we've sold nearly two years' worth of merchandise since the siren.

After breaking a 57-year premiership drought with a team that is already speaking of its determination to win more flags, president Kate Roffey declared it was a new era for the club.  

"Someone said to me last night, the Melbourne football club is back at the very epicentre of the AFL world and that's where we deserve to be," Roffey said.

"We're going to stay there for a while as well … it's a new era for Melbourne.

"We're very proud to have won here and we will proudly take it back home to Melbourne."
