Fantastic century from Ponting. Obviously it's still a flat wicket, but there was plenty of pressure and some good bowling, and he was rock solid after the drop. He's simply the best batsman in the world, and his record since last Ashes is incredible. He's come away from that series with a point to prove, his captaincy has improved and he's scored 10 centuries in his last 13 tests.
Averaging over 60 now, more centuries than any other Australian cricketer and getting better as he goes.
Hussey has been very good too. As soon as he came in he took the right approach under the circumstances, has barely played a risky shot and left everything wide of off-stump in his first hour at the crease. Flintoff has troubled him with some good bowling, but Hussey's selection of which delivery to play has been flawless, which is where batsmen like Hayden, Gilchrist and Katich have fallen down playing Flintoff when he comes around the wicket.
Second session Australia have won in the test anyway. If they don't lose more than one or two post-tea it'll be a decent day, and the result is still alive as long as these two stay at the crease.
