Stand-in Australia captain Nathan Sharpe has warned his teammates that they face a difficult test against Argentina in Saturday's Rugby Championship fixture.
Australia are favourites for victory but Argentina have impressed so far in the tournament, with a series of determined performances.
"They're a very passionate team and it's something that's been identified in the first games of the Rugby Championship and one that you look at in every World Cup, they're always competitive due to that spirit," said Sharpe.
"The thing about them as a team is they play well as a team. They don't generally have a consistent stand-out, they just perform well and put in for each other and that's what makes them a dangerous team."
The Wallabies go into the match without senior players including Will Genia, David Pocock and James Horwill.
