When the VFL's Umpires Panel counted the Brownlow Medal votes that had been awarded during the 1930 season, it found that three players had been considered best on the ground on four occasions: Harry Collier of Collingwood, Allan Hopkins of Footscray, and Stan Judkins of Richmond.
In 1981, the league changed Brownlow Medal rules to allow more than one player to receive the medal if tied on votes; and, in 1989, it retrospectively awarded medals to Harry Collier and Allan Hopkins for 1930.
