It encompasses smaller senior clubs in the Mid-West and Central West of the state.
The competition began as the Group 9 Second Division in the 1940s, with clubs from towns such as Binalong, Stockinbingal and Boorowa among others.
The competition has slowly moved north however, and effectively operates as the Group 11 Rugby League second division, with only Grenfell remaining from the Group 9 days, something that was reflected in the name change to the Woodbridge Cup in 1990.
There will be 14 clubs competing in the Woodbridge Cup in 2023, with Cowra and Blayney entering from Group 10.
This is on top of three teams merging in from the now defunct Mid West Cup in 2022, including CSU Mungoes, Orange United Warriors and ex-Group 10 Rugby League powerhouse Oberon Tigers.
