The 1989 Australian Grand Prix was a Formula One motor race held at Adelaide on 5 November 1989. It took place in wet conditions, and was stopped and restarted following a first-lap collision. Andrea de Cesaris spun at the same corner on two consecutive laps. As Formula One cars are not as fast in wet conditions as they are in the dry, the race was stopped at the two-hour mark with 70 laps being completed, 11 short of the scheduled 81 laps.
