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.
