The 1999 Westar Rules season was the 115th season of the various incarnations of the West Australian Football League and the third as “Westar Rules”. It is most notable for the first winless season in open-age Western Australian football since Midland Junction in their final 1917 season lost all twelve of their games, although South Fremantle in the under-19 1944 competition lost all nineteen of their games. Peel Thunder, who at the completion of the season had won only two of their first sixty Westar Rules matches, achieved the equal second-longest winless season in a major Australian Rules league behind SANFL club Sturtin 1995. Although beforehand most critics thought the Thunder would improve on what they did in their first two seasons, late in the season none of the major Westar Rules writers gave them a chance to win even against second-last East Perth at Rushton Park. In the process Peel became the first team for fifty-four seasons to fail to score in the first half and suffered the second-worst loss in open-age WAFL football. Amazingly, the Thunder's only near miss was against minor premier South Fremantle in the last round, when they led all day only to lose by seven points. Their inept performances led to controversy concerning the Thunder's existence among both critics and other Westar Rules clubs, which were to come to a tipping point in subsequent WAFC reports on the state of the competition, notably the “Fong Report” after the 2000 season. Apart from Peel's ignominious season, East Perth, suffering from internal dissent and disputes over where they would play their home matches – Perth Oval was scheduled for redevelopment as a rectangular field for soccer clubPerth Glory, – fell from fourth to second last in their worst season since 1989, winning only twice against the top seven clubs. South Fremantle and West Perth established themselves as the competition's heavyweights with a run of spectacular performances. Despite the pre-season loss of Peter Sumich and Scott Watters, the Bulldogs, aided by access to Docker players under the first host club scheme and whose season featured numerous “centenary year” celebrations, won fifteen on end after an opening round defeat and the Falcons lost only once in the final fifteen home-and-away rounds.
