Michael Hooper has been confirmed as the Wallabies' new captain following last week's news that Stephen Moore will retire from international rugby at the end of the year.

The 25-year-old has captained the Wallabies on 15 occasions but his new appointment indicates he is the man Michael Cheika wants to lead Australia at the 2019 World Cup in Japan.

Hooper took over the captaincy from Moore in the June Tests against Fiji and Scotland before standing aside for the Italy match in Brisbane.

With Moore announcing last week he would be stepping down immediately as the team's leader, Hooper now has the task of getting the Wallabies mentally ready to tackle the All Blacks in the first Bledisloe Cup match on August 19.
