Thirds Premiership Winners
The Thirds competition was introduced for the top two sections in 2010 with a Premier C Thirds competition added in 2012. Due to the increase in participation and disbandment of Club 18, the Thirds competition expanded to Premier, Section 2-5 in 2018 before being re-structured to Premier, Division 1-4 and U23’s in 2019.
