James Horwill will captain Australia in the Test series against the British and Irish Lions and troubled back Kurtley Beale has also made the final squad, the Australian Rugby Union said on Monday.
Horwill, the Queensland Reds lock who was Australia's 2011 Tri-Nations-winning skipper, returns to the captaincy after a hamstring injury last year ruled him out of the entire Test season.
Beale, who has been undergoing rehabilitation for alcohol problems, was among the final six additions to the Wallabies squad along with Hugh McMeniman, Digby Ioane, Pat McCabe, Peter Kimlin and Scott Sio.
Backs: Adam Ashley-Cooper, Berrick Barnes, Kurtley Beale, Nick Cummins, Israel Folau, Will Genia, Rob Horne, Digby Ioane, Christian Leali'ifano, Pat McCabe, James O'Connor, Nick Phipps, Joe Tomane
Forwards: Ben Alexander, Dave Dennis, Kane Douglas, Saia Fainga'a, Liam Gill, Michael Hooper, James Horwill (capt), Sekope Kepu, Peter Kimlin, Ben McCalman, Hugh McMeniman, Stephen Moore, Ben Mowen, Wycliff Palu, Benn Robinson, Rob Simmons, Scott Sio, James Slipper
