Australia's under-20s rugby team have made a successful start to the junior world championship in Argentina, walloping Scotland 58-13 in their opening pool match.

Winger Aidan Toua collected two of Australia's nine tries in the bonus-point victory in Santa Fe.

Wallabies 2009 spring tourist Luke Morahan, skipper Jake Schatz, Melbourne Rebels halfback Luke Jones, Brumbies pair Robbie Coleman and Colby Faingaa and winger Greg Jeloudev also found the try line.

Brumbies flyhalf Matt Toomua kicked five conversions and a penalty goal.

Seeking an elusive first-ever junior world championship, Australia, under coach David Nucifora, are the youngest side at the tournament.

"They played very well in the first half to get 34-6 up. We scored five tries before halftime and secured the bonus point which was really good," Nucifora said.

"The team controlled possession really well, made the Scots make a lot of tackles and essentially, through being patient, opportunities came and we scored some quality tries." Australia will play Tonga in their next pool match on Wednesday in Parana.
