RUGBY: Wallabies coach Michael Cheika has once more tinkered with his back row in an attempt to end his team's six-game losing streak.
Cheika has brought Dean Mumm, usually a second-rower, in to replace Scott Fardy as blindside flanker, with Fardy missing out on the matchday squad altogether.
It means the so-called "Pooper” back-row experiment of Michael Hooper on the blindside and David Pocock at No.8 will continue as Australia looks to break its duck with a first win in this year's Rugby Championship at Suncorp Stadium on Saturday night.
Mumm is one of two changes to the starting XV from the last-start loss to the All Blacks.
Melbourne Rebels back Reece Hodge will make his starting debut after impressing in the second Bledisloe Cup Test.
The 21-year-old, who came off the bench to replace Adam Ashley-Cooper, will line up on the left wing, with Dane Haylett-Petty moving to the right.
Drew Mitchell had to settle for a place on an extended bench and is set for his first Test since the World Cup final and his first rugby match since May.
Western Force lock Adam Coleman keeps his place alongside Kane Douglas, with Cheika selecting the same second-row combination for the first time this year.
Lopeti Timani could make his debut from the bench.
It appears as if Timani will go head-to-head with Sean McMahon for the final spot among the reserves.
Springboks coach Allister Coetzee has also made changes from the side that lost 26-24 to Argentina last time out.
Centre Juan De Jongh is set to start alongside Jesse Kriel after returning to the 15-man squad following his stint in the Rio Olympic sevens.
One of De Jongh's Olympic teammates, Francois Hougaard, has also been handed a starting spot, lining up on he left wing, pushing Bryan Habana on to the opposite edge.
Hougaard replaces the injured Ruan Combrinck, who broke his leg against Argentina.
Coetzee has gone for six forwards on the bench as he expects a big battle up front.
"The Wallabies are known for their ability to hold on to the ball for long phases, so we are preparing ourselves to make a lot of tackles and to be organised on defence,” he said.
Coetzee said he was looking for his substitutes to give the Boks fresh impetus as the game wears on.
"Our bench has made a real impact in each match we've played this season,” he said.
"After looking at the Australia versus New Zealand matches, we realise the physical intensity of the forward exchanges, and that's why we feel that a fresh tight five can sustain the physical intensity.”
