The Wallabies have been boosted by the return of star back-rower Tom Hooper for Saturday's second Test against Japan in Townsville.
It comes as the Wallabies look to shrug off the jet lag and the effects of sweltering conditions during their 35-32 win over the Brave Blossoms.

Hooper will link up with the squad as they make base in Brisbane following their return from Osaka.
The 25-year-old has recovered from a shoulder injury suffered during the opening Test of the year against Ireland.
It would be Hooper's first game in Queensland since his decision to commit to the Reds and return to Australian Rugby in 2028.
"Tom is very close...We'll have a report on where we are at the moment, and then we'll make a decision tonight whether we do bring Tom or someone else in. But at this stage, I'd like to see how this evening pans out," coach Les Kiss told media in Osaka about bringing Hooper in.
Centre Len Ikitau remains out, dealing with an ankle injury picked up in the win over Italy last month.
Kiss has forecast changes for Saturday's Test, set to be forced into at least one after Miles Amatosero's red card.
Amatosero is likely to have his case heard in the coming days after his dangerous cleanout on Japan skipper Warner Dearns was upgraded from a yellow.
"I understand what they're seeing but we only looked at it once, so we'll have a look at it. We'll live with the decision now and we'll have a good look at it," Kiss said.
"Whether he was falling or whatever, that's for other people to decide."
Hooper would be a natural replacement, leaving Jeremy Williams to start, whilst the likes of returning second-rower Lukhan Salakaia-Loto and Lachlan Shaw are other options.
"This trip took a lot out of a lot of guys, so we're going to have to look at where the energy is," Kiss added.
"We've got to fly back and we're going to stay in Brisbane for a few nights just we don't have to do the double travel, manage that energy in that way.
"I'd imagine there might be one or two tweaks just to help us get through this period. The heat's been pretty tough here. [Saturday] was a fast game."
