This series could very well end up 4-0 England if Australia don't pull up their socks.
Their bowling has looked so toothless. Half their lineup is either injured (Katich, Clarke, Bollinger) or woefully out of form (North, Johnson). Ponting hasn't clicked when it matters. Doherty is looking out of place at Test level. The whole bowling attack seems to be bowling without a plan, or bowling with really bad ones, which puts further doubts over Ponting's captaincy.
With Doherty's ineffectiveness, and Bollinger seemingly struggling through his spells, all Ponting has left is Siddle and Harris who haven't bowled too badly.
This is what Australia gets for not dropping North and Johnson sooner, and for dropping Hauritz for an untested spinner. KP has scored 46 runs off 54 balls he's faced from Doherty. So much for that experiment.
And then the batting. Clarke does not look like he should be playing. He's struggling. North has been there wayy too long, you just feel he's being played because he's a second spinner. 2 holes in the batting lineup, and with Ponting failing so far, that's 3 wickets for not many to begin with. Watson and Katich aren't Hayden/Langer, and will be prone to occasionally failing with Anderson in the form he's in. Hussey and Haddin have done quite well and are the reason Aus are still fighting.
It's not even clear what Aus can do to turn this around. A start might be dropping Doherty and North and bringing in Haurtiz and a new batsman like Khawaja/Ferguson or even Smith.
Next step might be dropping Bollinger and Clarke, who don't seem fit enough, and bring in Hilfenhaus and another batsman.
Or they could just stick with the current squad and hope things come together.
Lead up to 303. KP now has 57 runs from 58 balls against Doherty.
