In 1955, the VFL competition consisted of twelve teams of 18 on-the-field players each, plus two substitute players, known as the 19th man and the 20th man. A player could be substituted for any reason; however, once substituted, a player could not return to the field of play under any circumstances. Teams played each other in a home-and-away season of 18 rounds; matches 12 to 18 were the "home-and-away reverse" of matches 1 to 7. Once the 18 round home-and-away season had finished, the 1955 VFL Premiers were determined by the specific format and conventions of the Page–McIntyre system.
The highest aggregate score in a match for the year was only 207 points, which is the lowest for any VFL/AFL season since 1922. There was no match where both teams scored more than 100 points.
St Kilda's average score of 47.8 per match was the lowest average by any team since 1919.
Towards the end of the Round 4 match between Fitzroy and Geelong at the Brunswick Street Oval Fitzroy full-forward Tony Ongarello was so upset with his own inaccurate kicking that, upon taking a mark, he indicated to the field umpire that he was going to kick a place-kick. He scored a goal. He was so impressed that he kicked one more goal in that match with a place kick. He kicked several goals later in the season from place kicks as well, but ultimately had little more success with place kicks than he had with punts. Although it has never been against the rules to do so, he is on record as the last player ever to score a goal with a place kick in a senior VFL match. Ongarello was not the first player to attempt to revive the place kick in 1955: full forwardColin Vance had unsuccessfully attempted a place kick for goal on debut three weeks earlier.
After North Melbourne's humiliating Round 11 loss to St Kilda – who had not won a match since Round 16 1954 and were now captain-coached by former North Melbourne star Les Foote – the North Melbourne committee suspended two of its senior players indefinitely from both playing and training with the club for "not having tried hard enough" in the match.
Defending Premiers Footscray missed out on a place in the Final Four by just 0.6%.
In the dying minutes of the Grand Final, Melbourne's 19th man Frank "Bluey" Adams rushed from the bench to take his place on the field and collided with the Collingwood winger Des Healey who, up to that stage, had been one of the beston the ground. Both participants in this horrific head clash were carried off unconscious. Healey had his nose broken in five places, a fractured skull, and never played for Collingwood again. "Bluey" Adams 15-second playing time is the shortest in VFL history..
