The Wales head coach has kept faith with the majority of the side that warmed up for the competition with a 29-22 victory over Scotland.
All the changes come in the pack with Cardiff Blues props Rhys Carre and Kieron Assiratti packing down either side of Ellis Shipp. They are joined by regional teammate James Botham, who replaces Aled Ward at No 8.
Will Jones will once again skipper the side and Strange has emphasised not only the importance of making a good start but strength in depth due to the short turnaround in matches.
Strange said: “It’s a competitive squad, which is always good for coaches. There were some tough selections but I’m really pleased with the team andhopefully we will do really well in our first game against Australia.
“The message to the squad has been whoever comes in has to take the opportunity so as disappointing it is for Kieron Williams and a couple of other players to miss out through injury, I’m sure the other players will more than embrace the challenge.
“It’s vital to get off to a winning start and not only in terms of the result but a performance.
“We’ve put a lot of focus on this first game and it’s important the players enjoy it and don’t become too nervous. It’s important that they relax, play with a smile on their face and express themselves because if they do that we’ll have a better performance.
“We’re confident, we have a good group of players, they work hard for each other and have a good team spirit so hopefully we’ll get the right result.”
Wales Under 18 captain Will Griffiths will win his first U20 cap in the encounter at Avchala Stadium in Tbilisi, as will Scott Jenkins and JoeGoodchild, if they come off the bench.
Following the big kick-off against Australia, Wales face England on Sunday (5.30pm BST) and Samoa on Thursday, June 8 (10am BST).
