Wentworth Park was originally a rugby league sports ground in the Glebe area, the home ground of the Glebe Dirty Reds who were a part of the New South Wales Rugby League premiership at the time of the competition's inception. The ground was also home to Annandale rugby league team throughout their existence from 1910-1920. After the Glebe Dirty Reds were removed from the competition at the end of 1929, Balmain Tigers continued to play some of their home matches at the ground. The final game of first grade rugby league played at Wentworth Park was in Round 2, 1931 when the Balmain Tigers played against University with Balmain Tigers winning 29-14. A question over the use of league or grounds gatemen led the League to decide to use other grounds.
