This is what I think...
Gillespie (if fit)
After the Pakistan series, I'd be putting *big* question marks on Mark Waugh and Brett Lee. I'd say that if they don't perform in this test, then they should get the kick. Simple as that.
If they don't perform, then the side for Adelaide should be:
Bichel (or MacGill/Hauritz depending on the deck)
Other possibilities should include...
Brad Williams - as a back-up pacer.
Stuart MacGill - as previously mentioned, if for some reason the selectors want a spinner but decide against Hauritz.
Michael Clarke - as the next batsman in line after Lehmann, followed closely by Maher.
