The Wallabies will take an unchanged team into Saturday night's second rugby union Test against Wales in Melbourne, with star fullback Kurtley Beale left out.

The ARU is investigating an off-field incident involving Beale at a Brisbane night-spot from last week, but coach Robbie Deans said today that Beale was left out because he still hasn't fully recovered from a shoulder injury.

Deans included prop Sekope Kepu, but the tighthead must prove his fitness later in the week after picking up an arm injury in last weekend's 27-19 first Test win over Wales in Brisbane.

Kepu strained a tendon in his forearm, but the fact he completed the full 80 minutes in game one before reporting the injury gives the Wallabies camp confidence he will pull through.

Ben Alexander replaced loosehead prop Benn Robinson during the first Test of the Tour but has played the majority of his 38 previous Test matches as a tighthead, and has once again been named as a versatile option on the bench.

Wallabies: Adam Ashley-Cooper, Cooper Vuna, Rob Horne, Pat McCabe, Digby Ioane, Berrick Barnes, Will Genia, Wycliff Palu, David Pocock (capt), Scott Higginbotham, Nathan Sharpe, Rob Simmons, Sekope Kepu, Tatafu Polota-Nau, Benn Robinson. Res: Stephen Moore, Ben Alexander, Dave Dennis, Michael Hooper, Nic White, Anthony Faingaa, Mike Harris.
