ADCA Semi-Finals and Preliminary Finals from five different seasons, nearly thirty years apart happened on this day for Waratahs.
In 1966, A grade missed out the final when rained robbed them and University of a positive result after Waratahs dominated the first day. A-Res grade snuck home by a wicket. In 1971, fortune was reversed, with A grade hanging on for a draw against St Peters and A-Res grade being done. In 1983, rain stopped 1sts from chasing 400 against Easts and a draw kept them from the Final, while 2nds were done despite a glorious first day hundred from Graham Johnson. In 1988, 1sts were Minor Premiers but lost in a shock to Hillgrove with a batting lineup which could afford Graham Frost at #8 and 3rds lost by 21 chasing 236 after being 3-0. In 1994, 4th grade, losing the Minor Premiership on percentages, were bundled out in straight losses in the final series.
