Siddle has definitely stepped up. I wasnt a fan of his technique but always a fan of his attitude (like Phil Hughes I guess). Seems that he has really picked up though this test.
Bowling wise, things are starting to look better for the side, but still not settled. At least there is a number of options and some good young pacemen coming through.
Batting is a big issue. Ponting and Hussey have probably just stayed the executions coming their way (but will be retiring soon). Haddin is stomping on thin ice now. If Paine wasnt injured, he would be in. Wade would be very close to getting selected now you would think though.
Marsh was unlucky. Cowan did good in one innings. Clarke needs to lift his game something shocking. Warner might be injured. I'm still not convinced he is test match material based on his rash shots.
