James Horwill has been dumped as Wallabies skipper amid a radical leadership overhaul which has swept controversial playmaker Quade Cooper into the vice-captaincy.
Thirteen months after his Test career was hanging by a thread following a "toxic" attack on the team environment, a forgiven Cooper has leapfrogged Horwill and Will Genia to be Ben Mowen's shock deputy.
Test rookie Mowen is captain for Sunday morning's (AEDT) tour-opening clash with England at Twickenham after coach Ewen McKenzie pulled the biggest selection surprise in Australia's professional era.
On it's own, Horwill's demotion is just as unexpected as his stunning ascension two years ago, when coach Robbie Deans replaced Rocky Elsom three weeks before the 2011 World Cup.
The Queensland lock would have also been dropped from the starting pack altogether if not for a training injury to in-form second-row partner Rob Simmons.
McKenzie refused to confirm Horwill was set to be benched but all indications were that Sitaleki Timani would replace him before Simmons aggravated a knee strain.
The coach admitted the 28-year-old's drop in form, caused by an injury-affected past 18 months, was the sole reason for being stripped of the leadership.
"I just want James to concentrate on his football," McKenzie said. "I know what he's capable of and the team needs him at his best.
"He's had a couple of setbacks (this year)... he hasn't had a smooth run. So at this stage I want him to be the hard-working abrasive second-rower I know he can be.
"We need his A game."
McKenzie had vowed he wouldn't shy away from making the big, tough calls required to turn around the Wallabies after they lost his first three Tests in charge and leaked 112 points.
Since then he's stayed true to his word by dropping Genia and demoting Horwill, his two trusted former Reds generals, banked on Mowen and sent James O'Connor packing.
"You get one chance at these things, and you're given what you've got, and I've been asked to make it better," McKenzie said. "My career in rugby has been about fixing things.
"I worked out in my very first year of head coaching that if you don't make hard decisions you won't get very far, and certainly nothing will change.
"If something comes along and I take the soft option, what am I going to expect from the playing group? You've got to lead by example."
A more respected Cooper has been given the v-c honours ahead of trusted stalwarts like Stephen Moore, Adam Ashley-Cooper and Ben Alexander.
It comes after those teammates have praised his improved maturity after getting many off-side during his rift with Deans last year.
"Everyone has acknowledged Quade has made massive strides in the last 12 months and this is another step toward recognition he does make a lot of decisions on the field," McKenzie said.
"I think Quade has demonstrated the totality of being a team member, and that's been a significant change."
Matt Toomua has been retained at inside centre ahead of Brumbies teammate Christian Leali'ifano while Nick Cummins (broken hand) and Scott Fardy (eye) return from injuries in the other changes.Wallabies: Israel Folau, Adam Ashley-Cooper, Tevita Kuridrani, Matt Toomua, Nick Cummins, Quade Cooper, Will Genia; Ben Mowen (capt), Michael Hooper, Scott Fardy, James Horwill, Sitaleki Timani, Ben Alexander, Stephen Moore, James Slipper.
