The team includes three changes from the side that beat Ireland 22-12 on Monday. Outside half Jarrod Evans (cheek), and centre Garyn Smith (hamstring) are out injured, Scarlet Daniel Jones and Osprey Joe Thomas coming into the starting line-up. The only other change sees Ryan Elias start at hooker.
Coach co-ordinator Allan Lewis said, “The team has progressed so much during the tournament that we didn’t want to make too many changes for this last game, other than the forced changes due to injury and at hooker, where Ryan and Liam (Belcher) have alternated in the starting XV.
“We are delighted to be playing Australia in what is a big game in terms of final tournament positions. Other than Japan, we have played only Six Nations games this season so we are thrilled to be able to have a crack at a southern hemisphere side.
“Having lost our opening two games, a good performance and result on Saturday would be a pleasing outcome from the remainder of the tournament.
“I feel it’s going to be a high scoring game. Our young coaches encourage an open, ball in hand game and from what I’ve seen of Australia, they like to play a wide game too.
“A number of the players from both sides played each other at Under 18 level in Wales two years ago which we won 26-12, scoring four tries, so our players can take some confidence from that. What is key is that we concentrate on our performance. If we continue to progress as a team then tries will come and the result will take care of itself.”
Highlights of Saturday’s game, and of Wales’ other matches in the tournament will be shown on S4C at 7pm on Saturday evening. The match is not being covered by the tournament host broadcasters, and therefore will not be available as a live broadcast.
