Australia national under-20 rugby union team

The Australia national under-20 rugby union team, nicknamed the Junior Wallabies, is the age-grade national side that represents Australia in rugby union at under-20 level. It has taken part in the annual World Rugby U20 Championship since that tournament began in 2008, when it replaced the separate under-19 and under-21 world championships, and it also plays in the Oceania U20 Championship and, since 2024, the U20 Rugby Championship. Its best finishes at the world championship are second place in 2010 and 2019, with third place in 2011 and fourth in 2009. The Junior Wallabies name was added to the under-20 crest before the 2018 season, although it had earlier been used for several other Australian selections. In 2026 Rugby Australia changed its selection policy to allow a small number of overseas-based players into the squad for the first time.
