Queensland winger Dominic Shipperley has been released from the Australian Under 20s squad to help boost the Reds' run into the Super Rugby finals due to their growing injury toll.

Brumbies flanker Colby Faingaa will captain the Australian Under 20s side at the Junior World Championship (JWC) in Italy in June.

Faingaa, the young brother of Wallabies twins Saia and Anthony, follows in his siblings' footsteps in leading his country at age-grade tournaments.

Saia led Australia's successful Under 19s campaign in Dubai in 2006, with Anthony his deputy.

Queensland fields the majority of players in David Nucifora's 26-man squad with nine representatives, while there are eight from NSW, six from the ACT, two out of WA and one Victorian.

New Zealand have won all three titles and not dropped a match since the JWC replaced the IRB's former age-grade tournaments, the Under 19 and Under 21 championships in 2008.

Australia's first game is against Tonga on June 10.
