In 1965, 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-way reverse" of matches 1 to 7. Once the 18 round home-and-away season had finished, the 1965 VFL Premiers were determined by the specific format and conventions of the Page-McIntyre System. North Melbourne Football Club moved its playing and training base from the Arden Street Oval to Coburg City Oval. The move was intended to be permanent, with some initial negotiations seeking long-term leases for up to 40 years, but it was ultimately cancelled after only eight months, and North Melbourne returned to the Arden Street Oval in 1966.
The VFL's leading goalkicker was John Peck of Hawthorn who kicked 56 goals; he was the third player to win the goalkicking when his team won the "wooden spoon", and the first since Roy Park of University in 1913.
*As a consequence of its 1981 decision to change its rules relating to tied Brownlow Medal contests, the AFL awarded a retrospective medal to Teasdale in 1989.

In the Round 2 match against Essendon, Hawthorn forward Garry Young sustained a painful injury from a hard knock. Hawthorn captain Graham Arthur stood over him and said "Get up you weak bastard", and Young returned to the play and did his best to continue. Eventually he left the ground and went to hospital where it was discovered that he had a perforated bowel and peritonitis, both of which are life-threatening conditions. He never played again.
