They are completing their build-up without the hands-on approach of their new scrum coach Petrus du Plessis.
He's still stuck in Britain due to a shortage of flights to Australia.
A former player-coach under Wallabies coach Dave Rennie at Glasgow, du Plessis has been contributing his offerings via Zoom, online videos and through new forwards coach, and former England international, Geoff Parling.
In du Plessis' absence, the experienced core in the Wallabies pack had worked with Parling and taken charge of the situation.
That's when it's helpful to have players like props James Slipper and Scott Sio who have played 96 and 63 Tests respectively.
Hooker Brandon Paenga-Amosa told rugby.com.au this week that he felt Parling had made a difference with the scrum.
"I can definitely see his experience. I've seen it a lot more even in the scrums because the emphasis he puts on the back-row [is] very similar to Brad Thorn, to make sure their body height is good, that they're tight, together and pushing at the scrum.
"That's what I love to hear as a front-rower, I love hearing our forwards coach get into our backrowers and back five, making sure they're giving us everything we can in the front row," he said.
Among those backrowers is likely to be former Crusader Pete Samu, who has returned to international consideration after not playing Test rugby in 2019.
"I didn't play as much Test footy as I wanted but being back in the squad [I'm] just pretty keen to start playing again and push for a starting spot.
"It was very frustrating just not knowing [why he wasn't in the team]. That's in the past now. I'm just looking forward to the first Test and pulling that jersey on again," he said.
Since ending his connection with the Crusaders, Samu has been playing for the Brumbies and enjoying himself.
At the same time, he was aware of the competition for places as an emerging group of young players are putting the heat on.
"There're some great young backrowers coming through and they're all putting their hands up for that starting spot.
"It's good to have that competition going for that No 8 spot, having Harry Wilson there. He had an awesome season. It'll be good to compete with Harry for that spot and we'll see how we go," he said.
