AJAX Football Club joined the VAFA in 1957 and have been one of the most well supported clubs in the competition since their inception. With a couple of runners-up finishes in their first three seasons the Jackas had progressed to Premier C, albeit without that most cherished premiership. They changed all that in 1966 when back in E Section, AJAX broke through for that first elusive flag. However it was their second E Section flag in 1975 that launched the club into their most successful period on field. AJAX backed up this flag with a runners up finish (losing to Old Xaverians) in D Section and the following year the club missed a third straight promotion when they lost the preliminary final to Parkside. It was deja vu for the Jackas in 1978 as they again went down to Xavs in the Grand Final, however the silver lining was the club had made it to B Section.

In 1979 was our most celebrated year to date, as AJAX went on to win the B Section premiership and reach A Section. The Jackas had climbed five sections in six seasons. AJAX had three years in A Section, the third year was thanks to Uni Blues being demoted on the eve of the 1981 season. Whilst the club hasn’t ventured back to Premier since then, they are on the right path. A Premier C flag in 2011 has seen a sustained run in Premier B, with the club on the cusp of breaking into the top flight again. At the start of 2017, the Jackas landed the highest profile senior coach of the off-season, with former Port Adelaide premiership coach Mark Williams taking the reins. It was also the same year their women’s team came over from the disbanded VWFL and formed one of the six teams in the inaugural Sunday competition. In 2018, the Jackas suffered relegation to Premier C for the first time in eight years, however after a successful 2019 reaching the Premier C Grade Grand Final, the Jackas were subsequently promoted to Premier B for 2020 season.
