The 1923 New South Wales Rugby Football League premiership was the sixteenth season of Sydney’s top-level rugby league club competition, Australia’s first. Nine teams from across the city contested during the season which culminated in Eastern Suburbs’ victory over South Sydney in the premiership final.[1] This season would be the last season that future Australian Rugby League Hall of Fame inductee Duncan Thompson played in, for he returned to Toowoomba after a dispute with North Sydney.

The top two sides, Eastern Suburbs and South Sydney, tied on equal points at the end of the season. Eastern Suburbs had previously been leading South Sydney by two premiership points coming into the final round of the year, only to lose to third-placed Balmain by one point in front of 14,000 people in their final match. South Sydney on the other hand won their final match against North Sydney to finish level on top of the ladder.
