Finals
Heading into the finals, top placed St. George and Eastern Suburbs were in top form, with St. George losing their only match in round 3 and Eastern Suburbs losing to St. George in round 7 of the 14-week competition. With Saints & Easts finishing on 26 points each, no playoff for the minor premiership was staged to award a right of challenge in the finals, thus negating the good work done by both sides during the premiership rounds and ultimately providing an easier route than otherwise for Souths to win the title away from both of the minor premiers.
In the semi-finals, Eastern Suburbs beat fourth-placed North Sydney to make the final, whilst South Sydney beat St. George, whom they had lost to 9-8 just three weeks earlier.
