The injury rates and the public perception of rugby league as a dangerous sport are most likely the catalysts for the introduction of several initiatives by the national rugby league and ARL development in recent years to curb the number of youth playing other sports. The specific initiatives over the years includes a Safe play code, Kids to kangaroos programmes and new forms of modified rugby league, such as, Mod league and Mini Footy to help young children prepare for the full rigours of the international code. Also with such introductions are the competitions aimed at school children such as Joey league, League of legends and League Sevens, which use modified rugby league rules such as Tag and Sevens.
