Fremantle's biggest rivalry is with the other Western Australian team, the West Coast Eagles, who they play twice each year in the home and away season, in the fiercely contested "Western Derby" matches (Pronounced in Western Australia). West Coast were victorious in the first nine games, before Fremantle won in round 16, 1999, after which has prompted a fairly even Derby result with Fremantle at 19 and West Coast at 21 Derby wins. The term "derby" is named after the Fremantle Derby games between East and South Fremantle in the West Australian Football League, which for almost 100 years have been considered some of the most important games in the local league. The 1979 WANFL Grand Final still holds the Subiaco Oval football attendance record of 52,781.
