The season featured sixteen clubs, ran from 27 March until 26 September, and comprised a 22-game home-and-away season followed by a finals series featuring the top eight clubs. The premiership was won by the Adelaide Football Club for the second time and second time consecutively, after it defeated North Melbourne by 35 points in the 1998 AFL Grand Final.
