The Junior Wallabies side to play Wales U20s in the opening clash of the World Rugby U20s Championship has been named with Ryan Lonergan to captain the side in the match on Thursday morning (Sydney time). Head Coach Jason Gilmore has made four changes to the side that faced New Zealand in the Oceania Rugby U20s Championship with Melbourne Rebels squad member, Semisi Tupou to play his first game in Junior Wallabies colours for 2018. “We’ve had a good preparation in the lead up to this match and the lads are looking forward to starting the World Championship," Australian coach Jason Gilmore said. “Wales are a very tough side and we know that they have some big bodies and will use the set piece really well, so we will need to front up to the challenge.” On the bench Australia will be supported by Queensland Reds scrumhalf, Tate McDermott and recent NSW Waratahs signing, Will Harrison. The match kicks off at 5am on Thursday 31 May and will be broadcast LIVE on FOX SP
