1997 Westar Rules season
Affected badly by the erratic availability of a number of AFL-listed players , reigning premiers Claremont had their worst season since 1975 and equalled East Fremantle's decline in 1980 from premiers to only five wins , whilst Swan Districts , brilliant but erratic during 1996 , began with nine wins in their first ten matches before losing eight of their next nine to miss the finals for the third successive season .
