Lucas De La Rua returns for Wales U20s as Mark Jones makes three changes for the U20 World Rugby Championship 5th-place final.
With Cam Winnett still sidelined, De La Rua is the only Blue and Black starting in Cape Town, with three teammates - Mackenzie Martin, Gwilym Evans and Harri Wilde - named among the replacements.
The back three of Harri Houston, Tom Fletcher and Llien Morgan remains the same, but Bryn Bradley starts at inside centre, swapping with Joe Westwood who drops to the bench. Bradley will be partnered by Louie Hennessey.
The halfback pairing of Archie Hughes and Dan Edwards remains intact for the fifth consecutive game.
Jones has picked the same front row of Dylan Kelleher-Griffiths, Lewis Lloyd and Kian Hire which started against Georgia but has brought in Evan Hill to replace his injured Ospreys colleague Liam Edwards in the second row. Jonny Green will pack down alongside him.
Lucas De La Rua, who scored as a replacement against the Georgians, starts on the openside flank, replacing Seb Driscoll with captain Ryan Woodman and Morgan Morse starting at blindside and No 8 respectively.
Cardiff Met prop Tom Pritchard is in line to earn his first appearance at the championship after being name on the bench.
Jones was delighted with the victory against the nuggety Georgians but expects the Junior Wallabies to provide an entirely different proposition.
“A lot of things came together on what we had been working on – it felt like we had put on a more polished performance together around our whole game,” he said.
“Our set piece finished strong against Georgia. Our team management was really good particularly in comparison to the second half against New Zealand. The boys learned the lessons, but we know for this match we are going to have to go up another couple of gears again.
“We’re expecting a much more expansive game, not that Georgia aren’t an expansive team but the conditions in Paarl were quite difficult under foot and the ball was a little bit greasy so we couldn’t move the ball into space.
“The pitch is going to be wider, drier and the weather prospects a little bit better overhead. I think Australia will look to move the ball to the edges a lot more efficiently than Georgia so they provide a different challenge. But I’m confident if we get the defence right like we did against Georgia, we can deal with it.”
