Brumbies backrower Colby Faingaa will make a timely return from injury to bolster the Australian under 20s pack for the final of the Junior World Championship against New Zealand in Rosario, Argentina on Tuesday morning (AEST).

Faingaa has recovered from an ankle injury which kept him out of the Young Wallabies' 28-16 semi-final victory over England on Thursday and also their crucial 42-25 pool match win over South Africa.

Queensland Reds recruit and Australian sevens representative Ed Quirk makes way for Faingaa's return to the side in the only change made by coach David Nucifora.

Australia will be seeking to derail New Zealand's bid for three successive titles, while four returning players - captain Jake Schatz, halfback Nic White, fullback Luke Morahan and flyhalf Matt Toomua - will seek to avenge their semi-final loss to the Baby Blacks in 2009.

Nucifora says the Young Wallabies believe they can hand the Baby Blacks their first JWC defeat since the tournament's inception in 2008.

"We're used to playing Kiwis, we play them all the time so they don't really hold that same aura that they may do for other teams," Nucifora said.

"Our boys play them from a young age, through school quite often, so I suppose we're used to competing with them and we know if we go out there and we match up and do our best, we are more than capable of beating them."

Team: Luke Morahan, Dominic Shipperley, Kimami Sitauti, Robbie Coleman, Aidan Toua, Matt Toomua, Nic White, Jake Schatz (capt), Liam Gill, Colby Faingaa, Greg Peterson, Phoenix Battye, Paul Alo-Emile, Siliva Siliva, Salesi Manu. Res: Sam Roberson, Cruz Ah-Nau, Luke Jones, Ed Quirk, Ian Prior, Jono Lance, Greg Jeloudev.
