Tag rugby is played by the Prep boys and it helps to develop running pace, coordination, spacial awareness and ball skills.

They enjoy the sense of freedom that the game brings and it is a good preparation for rugby at senior school.

It is a minimal contact team game in which each player wears shorts with Velcro patches with two tags attached to them. The method of play is similar to rugby league, touch rugby or rugby sevens, with attacking players attempting to dodge, evade and pass a rugby ball while defenders attempt to prevent them scoring by 'tagging' - pulling a Velcro-attached tag from the ball carrier. The attacking team has six plays or tags to try to score a try or take the ball down field as close to the line as possible. Tries are worth one point and there are no conversions. The team scoring the most points will win the game.

There are a number of differences in the rules of tag and touch rugby. The main difference is a tag needing to be removed to constitute a tackle, as opposed to making a touch. The other main features of tag that are different to touch include kicking being allowed, the ball being allowed to touch the ground, and a marker being allowed to stand in the ruck. This means the dummy half can score tries or be tagged.

A standard match is 40 minutes long, consisting of two 20-minute halves. All the boys participate in fixtures and tournaments and there are inter-house games.
