Australia chief Michael Hooper has removed from Saturday’s Rugby Championship opener away to Argentina and will get back as he isn’t morally justified “attitude” to play.
Rugby Australia said Hooper had educated the group regarding his choice.
Wallabies mentor Dave Rennie said Hooper had “shown genuine boldness”.
“While this choice didn’t come effectively I realize it is the right one for myself and the group as of now,” said Hooper, 30.
“My entire profession I’ve hoped to put the group first and I don’t feel I am ready to satisfy my obligations right now in my ongoing mentality.”
Prop James Slipper will lead the side in Mendoza with Fraser McReight supplanting Hooper as flanker.
Hooper, who made his Wallabies debut in 2012 and has won 121 covers, last year passed George Gregan’s record for most Tests as chief.
Rennie said: “Michael’s quite possibly of the most expert and noteworthy man I’ve trained – I know this has been a tough choice for him.
“He’s shown genuine boldness by recognizing where he is at and following up on it.
“We will uphold him in any capacity we can and I realize the group will be centered around taking care of business tomorrow [Saturday].”
Rugby Australia CEO Andy Marinos added: “Michael is an extraordinary pioneer, it takes a courageous man to recognize where he’s at and approached while having the wellbeing of the group on a fundamental level.
“His prosperity is and stays the most noteworthy need right now where Rugby Australia and the Australian Rugby people group will do all that to help him and his loved ones.”
