Sutherland defeated Sydney University in the final under lights at the SCG to win the T20 premiership. This is the report that was posted on the club website the following day:

Our boys played great cricket to carry off the Kingsgrove Sports T20 Cup at the SCG last night – the only competition that we had not previously won. Disciplined bowling and fielding ensured that we strangled the opposition batting in both matches, thus enabling comfortable run chases both times.
