I'll give it a shot
1, 2, 3: I really don't know, probably Polata-Nau as 2 and Rodney Blake with Robinson. This is the area where the Wallabies usually do very poorly and so long as Dunning or Baxter aren't picked I'll be happy.
4, 5: Vickerman is a must here in my opinion, partnered by Horwill I would say, but keep players like Mumm and Chisholm in the squad. Sharp really isn't that great a player, at least I think so.
6, 7: Elsom and Smith to start with Pocock on the bench but Waugh could get a look in here. Chisholm and Hoiles could also cover some of these positions.
8: Palu is our best option I believe, with Hoiles on the bench we should have plenty of players that can cover this position if Palu has to leave for whatever reason.
9: Burgess, he gets the ball out quickly from the ruck, exactly what we needed against England and didn't have with Gregan playing.
10: I like Barnes here, with Giteau at 12 but you could easily swap them around.
11, 14: It's a pity that Mitchell is injured now as I reckon he's a great player and should have definitely secured his test spot after his performances in the World Cup but for now have Gerard. As for the other winger, Tiquiri, with turner on the bench to cover a few spots.
12, 13: Giteau or Barnes at 12 doesn't really make a massive difference in my opinion. Mortlock has done enough since coming back from injury to earn a spot in the run on side, but Cross should get a look in (although he might be injured?)
15: Sheppard, don't really have a fullback that can make something from nothing like Latham any more but both Shepard and Gerard have good boots on them which is what we need now.
That's the team that I reckon could serve us well in future years, we need to get some young guys in and train them up for the next world cup.
