Club records
On July 23, Souths recorded a 67–0 win over Western Suburbs in Round 8. This remains the club record for largest win margin in a game. It is also the largest win margin performed by Souths against a defunct NSWRL/NRL team (assuming the existing Wests Tigers are a separate entity to the Western Suburbs club).
