The Wallabies have a new captain with Ben Mowen to lead the team into action against Argentina on Saturday night after Will Genia was dumped from the starting XV on Wednesday.

Mowen becomes the Wallabies sixth captain in two years and will take over the reins in just his seventh Test, making him one of the most inexperienced skippers in Australian history.

Halfback Genia has been axed to the bench with rookie Nic White to take over the No.9 duties.

Wallabies coach Ewen McKenzie revealed the decision to bench Genia was not taken lightly, "The fact that Will has captained his country shows what high regard we hold him in, and while he is naturally disappointed, I also know how competitive he is and I've got no doubts he will train himself to a standstill to bounce back as a better player," McKenzie said.
