Michael Clarke has announced an unchanged line-up for Australia's second Test against India, starting at the SCG tomorrow.

The selection news leaves returning paceman Ryan Harris as 12th man, giving Clarke the option of using Nathan Lyon heavily with the pitch tipped to spin later in the match.

"It's a tough call on 'Rhino'. He's been a wonderful bowler for us and I love having him in and around the group," Clarke said.



"It was tough to leave him out but we've stuck with the winning team in Melbourne.

"The way we performed in Melbourne it's tough to change that team. We've had a long enough break as well, that was probably the other consideration. Finishing the game a day early, and the bowlers not bowling too many overs in the second innings, that has certainly helped them."
