Chisolm? Seriously? That guy and Dean Mumm should never play for the wallabies again. They've had their chances and they've blown them. McCallman is in the same position, but if Palu doesn't get some gametime soon, he is the only option. My 30 would be:
1. Robinson
2. Moore
3. Slipper
4. Horwill
5. Sharpe
6. Elsom
7. Pocock
8. Palu
9. Genia
10. Cooper
11. Mitchell
12. O'Connor
13. AAC
14. Ioane
15. Beale
16. Polota-Nau
17. Alexander
18. Pyle
19. Higginbotham
20. Burgess
21. Giteau
22. Turner
R. Fainga'a
R. Kepu
R. .... Simmons?
R. Beau Robinson (if Pocock gets injured for a game or 2)
R. Phipps
R. Barnes
R. Fainga'a/Mortlock/Cross/Horne or some other big, fast guy in case something happans to two-dads.
R. Gerrard
Of course, that squad depends on fitness (Elsom, Palu) and on how do some of them do on the 3N (Pyle, Phipps, Robinson, Kepu).
As a general thing, I think that the front rowers pick themselves. The locks, there are several that are on a fairly similar level, so it is basically Sharpe +3. The backrow is perhaps the most complicated. Pocock will be there for sure and if Elsom and Palu find some S15 gametime they should start. The other two are because the Reds backrow are kicking everyone esle's asses, even Force (and we'll see how they do against the Saders). Next in the pecking order would have to be McCalman, Hogdson and Samo.
Of the 14 backs, I think that at least 8 or 9 are unanimous, and the rest I picked themto keep some flexibility. Mortlock might still find a way in, though.
What is wrong with McCalman? He was great for Australia last year; he has certainly taken his chances at test level. He has had a solid season with the Force so far this year, and I'd be very surprised if he wasn't in the 30-man squad (indeed I would probably expect him to be starting).
I think the 30-man squad will look something along the lines of:
1. Robinson
2. Polota-Nau
3. Alexander (I've gone for the experience of Robinson and Alexander in the front row, but potentially Slipper could force his way ahead of either Robinson or Alexander with some strong performances in the Tri-nations)
4. Horwill
5. Sharpe
6. Elsom
7. Pocock
8. McCalman
9. Genia
10. Cooper
11. Mitchell (assuming he is fit)
12. O'Coonor (personally I think they would be better with someone like Faingaa to complement Cooper [with O'Coonor on the wing], but it looks like they will play O'Coonor at 12)
13. Ashley-Cooper (I'd be tempted to try Ioane at 13, but I'm not sure if his distribution skills are good enough..)
14. Ioane
15. Beale
16. Moore
17. Slipper
18. Chisholm
19. Higginbotham (though potentially he could start at 8, or at 6 if Elsom doesn't recover in time/gets injured yet again)
20. Burgess
21. Giteau
22. Turner
23. Faingaa
24. Kepu (though Daley may be an option)
25. Mumm (Rob Simmons and Hugh Pyle are certainly options if either Chisholm or Mumm are dropped)
26. Hodgson / Beau Robinson / Palu (Beau Robinson would be the second best 7 in the country, and if Palu gets back to top form he may get picked, while Deans does seem to favour Hodgson's versatility. They cold potentially go with a 17/13 forward split, in which case 2/3 of these players may be included).
27. Phipps/Valentine/Sheenhan (not sure here)
28. Barnes
29. Faingaa
30. Shepherd/Hynes/Davies/Morahan/Gerrard/.... (not sure here either, plenty of options, but no clear standout in my opinion).
