- May 18 – In the final quarter of a VFL match between Essendon and Collingwood at Windy Hill, a drunk Essendon fan jumped the fence and punched field umpire Ray Sleeth in the face.
- October 26 – In the Olympic football final, Bulgarian fans threw various objects onto the field in the 44th minute with Hungary leading 2–1 to protest the officiating after three Bulgarian players, Tzevan Dimtriov, captain Kiril Ivkov and Atanas Christov were ejected, causing a 15 minute delay. Dimtriov was ejected for a dangerous tackle on Hungarian striker Antal Dunai while he was taking a shot at goal, as was Ivkov immediately after for arguing with the referee. As Dimitriov and Ivkov, who had been booked before the match for a brawl in the tunnel with Hungarian players, were making their way off the pitch, Christov picked up the ball and drop-kicked it towards the referee in protest, and was promptly ejected. With Bulgaria down to eight men for the second half, Hungary won the match and the gold medal 4–1.
