Australia have made three changes to the side to face Argentina in the Rugby Championship on the Gold Coast on Saturday.





The big news for Ewen McKenzie' side is the return of hooker Tatafu Polota-Nau after six weeks on the sidelines with the hooker set to make his 50th test match appearance for the Wallabies, who come into the game on the back of a last-gasp win over South Africa last Saturday.





Wycliff Palu (concussion) and Adam Ashley-Cooper (neck) are both ruled out through injury which means there are places in the the starting line-up for Western Force back row Ben McCalman and Waratahs winger Peter Betham.





Betham got the vote to start ahead of Joe Tomane, who is back in the squad after injury, and Tom English.





James Hanson, meanwhile, returns to the replacements bench is the only change from last week with the Queensland Reds hooker start providing cover for Polota-Nau.





“Tatafu has been a true servant to the game of Rugby in Australia for a long time and I couldn’t be more pleased to see him earn his milestone 50th game for the Wallabies this week,” McKenzie said.





“I’ve known Tatafu for a long time and he is guy who puts his body on the line each and every week for the benefit of the team. He gives it his all every time he takes the field and is also an outstanding teammate off it."





He added: “It’s always hard to replace the experience guys such as Wycliff and Adam bring to the game, but their injuries now open the door for Ben and Peter to get an opportunity on Saturday night.





“Ben is no stranger to the international arena and we feel he has certain characteristics which will suit the team for the beginning of the match. He’ll set the tone early with his high work-rate and provide a good balance for what we’ll be looking for from our backrow as a group.





“We’ll also then have the benefit of being able to call on Scott (Higginbotham) and Matt (Hodgson) from the bench late in the game. We have strong thoughts on how we want our ‘finishers’ to play and they all have defined roles in how we want to close out the match.





“We saw that with both guys making a significant difference to the outcome of the match against South Africa. That’s exactly what we want, and we will be hoping for more of the same against Argentina."
