Australia head coach Michael Cheika has made two changes to his starting line-up for Saturday's Rugby Championship game against Argentina at Twickenham.
Lopeti Timani replaces the injured Sean McMahon in the back-row, beating Bath-based Leroy Houston for the Wallabies No 8 shirt.
Houston may yet earn a Test debut via the bench, which has yet to be finalised.
The towering Brumbies lock Rory Arnold will start in the second row alongside Adam Coleman, at the expense of Rob Simmons, in the only other change to the starting line-up from last weekend's 18-10 loss to South Africa.
In opting for the relative inexperience of Timani (one Test) and Arnold (four Tests), Cheika said the Wallabies could have no fear in backing young stars.
"We can't be frightened to do that. No matter what game it is, whether it's Argentina or anyone else," he said.
With the versatile Dean Mumm - a line-out specialist - making his home starting at blindside flanker, Cheika believes the Wallabies need a hard-runner at the back of the scrum in the mould of veteran Wycliff Palu.
"I think with the profile of the other players we have, like the sixes who are more the jumping-type sixes, that ball-carrying, Wycliff Palu-style No 8 is something that we want to have as well," Cheika said.
"We want to be able to do both. Leroy [Timani] is quite an abrasive runner as well, so there's a great opportunity to [see] how he'll go with the step up."
Arnold has impressed off the bench for Australia and earns the start ahead of Simmons, who suffering a head knock against the Springboks but has passed all concussion protocols.
Speaking about picking Arnold, Cheika said: "He's just been aggressive, his lineout jumping has really improved, his mobility, ball carrying and every time he's come onto the field from the bench he's made an impact as a finisher.
"I just think it's a real opportunity for him."
