The Wallabies have received a triple boost with Tom Hooper, Carter Gordon and Brandon Paenga-Amosa set to be fit to take on Scotland on Monday (AEDT) in Edinburgh.
The boost comes after a tough loss to England left the team hungry to rectify the mistakes of the past week.

All three missed the defeat at Twickenham, with flyhalf Gordon the most notable, still returning from a broken leg against Argentina in September.
Hooper (shoulder) has been dealing with the injury suffered during the July series, re-aggravating it with Exeter last month.
"Everyone's on deck. We had a full training group last week and those boys were in our sessions," scrum coach John Ulugia said.
"Tom Hooper's a good player to have within the group, so we've kept close tabs on him. We're just ticking the boxes there off his shoulder, making sure he's good to go and then hopefully by Friday when we name the team, he's part of our group."
As for Paenga-Amosa, the hooker has dealt with a slight knee issue that has hampered his preparation, sporting a knee brace at the RA Awards last month.
"He just had a bit of knee bruising from our training camp in Sydney but nothing that could have stopped him from being called up [if needed]," Ulugia believes.
"He's got a wealth of experience at this level and played in Top 14, so he understands the importance of set-piece and adds a bit of experience there."
Ulugia believes the team should embrace the emotions of the loss, their third in a row, as they look to rebound against a dangerous Scotland outfit.
"I think we need it. We don't need to stay in it too long," he suggests.
"From a motivational side of it, we're looking forward to the home World Cup and obviously building towards that, we need to make sure that we're performing away from home to build our confidence.
"Also, with the new coaching staff building towards 2027, getting some good results on this side of the world [is huge]."
