The game changes in junior rugby. The teams compete in the SJRU competition, and each age group plays in a graded competition. Teams will play against four districts, namely: Manly, Warringah, Gordon and Northern Suburbs. Games are played on Friday nights and Sundays and are played at venues from Drummoyne to Hornsby across to Newport and down to Mosman.
The U10 and U11 age groups play 12 a side games and on a full length field, although narrower. The games are fully contested but the rules of the game have been modified in order to create exciting rugby for both the players and the spectators.
At U12 and upwards the games are played 15 a side on a full size field; as with the U10 and U11 game it is fully contested but using the U19 rules.
