In 2021 the Oysters lost to Redfield 28-29 in Round 4 at Lyne Park.
In 2023 they lost to Beecroft 33-7 in Round 5 at Headen - the only time they've ever failed to take competition points from a match.
They've scored a winning BP in every victory except the 12-10 win over Epping in the pouring rain in 2022 (R9 @ Woollahra #1).
With an average winning margin of 29 and a defense that averages < 14, that's a pretty decent record for 3 Premierships.
