The National Youth Competition (sponsored as the Holden Cup) is the official development competition for the Australian National Rugby League. It commenced in 2008 and was originally known as the Toyota Cup. The competition consists of teams from the 16 clubs that presently participate in the NRL competition, fielding squads made up of players between the ages of 17 and 19. The draw and structure mirrors the NRL, with games played as lead-ins to the corresponding first-grade NRL games. The competition uses a salary cap in the same way as first-grade NRL, and puts a heavy focus on life outside of football for the players. Matches are traditionally played prior to NRL games including the premiership final which is played in the same venue prior the NRL Grand Final.

The New Zealand Warriors are the most successful club in the National Youth Competition's short history, with two premierships already to their name, both coming in 2010 and 2011. The most recent premiers are the Wests Tigers. They are the first Sydney based club to win the Toyota Cup.
