It is a 19 team competition with teams divided into two sections, ten teams in section 1 and nine teams in section 2. It is a round robin format, with every team playing each other once and a bonus points system being used to rank the teams.
The Second Division operates under a similar format to Division One, with a full round robin to determine the winner of the Cup, before splitting into two divisions that eventually compete for the Trophy, Plate, and Bowl.
