Offspinner Nathan Lyon has retained his spot and fast bowler Ryan Harris, who did not recover from injury in time to be part of the Melbourne Test which Australia won by 122 runs last week, has been named as the 12th man.

Skipper Michael Clarke on Monday said Harris has "been a wonderful bowler for us... it was tough to leave him out, but we've stuck with the winning team.''

There had been speculation that Harris could be recalled as part of an all-pace attack for the 100th test at the SCG, which has lost its reputation as a turning wicket in recent years.

"We've had a long-enough break as well and that was probably the other consideration,'' Clarke said ahead of a training session Monday. "Finishing the (first test) a day early and the bowlers not bowling too many overs in the second innings has certainly helped them.''
