Ponting made 137 after becoming only the third batsman to reach 13,000 Test runs. Australia captain Clarke, who won the toss, struck 140 as his team seeks to wrap up a 4-0 series win.
Ponting earlier passed 13,000 Test runs in his 275th innings at the elite level. The only two players to have scored more Test runs, Sachin Tendulkar (15,432) and Rahul Dravid (13,262), were fielding at the Adelaide Oval today.
