The premiership was won by the Essendon Football Club for the 15th time, after it defeated Carlton by 44 points in the 1993 AFL Grand Final.

• Following the release of the Crawford Report, prepared by insolvency expert David Crawford, the clubs voted to make several significant changes to the administrative structure of the AFL during the 1993 season:
  • Firstly, the AFL Commission was expanded from six members to eight, and was given the power to make most administrative decisions relating to the league unilaterally (as opposed to ratification by a vote of club presidents).
  • Secondly, the AFL Board of Directors, after 96 years of operation, voted itself out of existence.^[3]
  • Thirdly, the clubs retained the right to veto any Commission decision by a two-thirds majority.
  • Fourthly, with several Victorian clubs, as well as Brisbane and Sydney, being concerned about their long-term viability at the time, a stipulation was also included that any decisions relating to the expulsion, merger or relocation of any club required ratification by a simple majority of all clubs, and the agreement of the club(s) in question.^[4]
• The Brisbane Bears, which despite its name had played its home games in Gold Coast at Carrara Stadium for the first six years of its existence, relocated to Brisbane in 1993. Its first home game at its new home ground, the Gabba, against Melbourne in Round 3 resulted in a win.
• At the conclusion of their Round 4 game against Collingwood, St Kilda's Nicky Winmar responded to racial vilification from the Collingwood cheer squad by declaring, "I'm black and proud of it!" while raising his jumper and pointing to his skin, an image which has since become famous. This was also St Kilda's first win at Victoria Park in two decades.
• Brisbane and North Melbourne both set club-record high scores in this season. North Melbourne's 35.19 (229) in Round 6 was then the fifth-highest score of all time, and Brisbane's 33.21 (219) in Round 8 was then the tenth-highest of all time. The opponent in both of these games was Sydney.
• In Round 18, a piglet with the word "PLUGA" and the number four painted on it was released onto the Sydney Cricket Ground during the match between Sydney and St Kilda; play was held up for two to three minutes as it managed to evade capture from trainers, security guards and players. The idea to release the pig had been devised by a small group of Sydney supporters and players the previous week, and was intended as a tactic to put dangerous St Kilda full-forward Tony "Plugger" Lockett off his game. As it happened, Lockett missed the game with injury, but was reportedly enraged when he saw the incident on television.^[5]
