This is most likely to be the Aussie playing XI for the 1st test at Cardiff:
1.P.Hughes
2.S.Katich
3.R.Ponting
4.M.Hussey
5.M.Clarke
6.M.North
7.S.Watson
8.B.Haddin
9.M.Johnson
10.B.Lee
11.S.Clark
I think this is pretty much going to be Australia's playing XI at the beginning of the series, and changes then might be made according to performances of the players, though having seen how gingerly Watto was bowling at the T20 WC, depending on his bowling too much in this series might prove to be a big mistake.
I guess this would have been mentione before, but still its surprising that the Australia squad doesn't have any reserve batsman, so in case one of the batsmen proves to be in disastrous form or gets injured on the eve of a test match, Australia basically won't have any out-and -out batsman to replace him with.
Your 11 looks great on paper but if Watto breaks down (again) and with North/Clarke/Katich only being part timers, you really are putting a workload on the 3 main quicks. If Watto is the reserve batsman, given his breakdown rate, should he being bowling at all?
They only place Hauritz might play is Cardiff, otherwise I actually think McDonald might actually play more test then many people think he will.
Anyway my main point was that his FC bowling stats are marginally better then either Hilf are Bollinger, and when given the chance against a good batting unit like SA he took wickets and tied down an end (precisely what was asked of him).
Andre,
If North is playing 6 and Watson's not in the 11 (outside of Cardiff), which 4 bowlers do you want....
Johnson is a certain, Siddle is a probable, then you've got Lee, Clark, Hilf and McDonald.
I think that Johnson, Siddle, Clark (cause his English record is so good but it'll come down to how they bowl in the lead up match between him and Lee) and McDonald to give variety. However if all 4 man quicks are bowling well it would be very tempting to play all four.
