A wise man (probably me) said: if its running sweet, don't fuck around with it. I'd imagine Cheika has done too much planning and put in too much work to see his apple cart screwed with now, especially in the centers where Mitch Inman has been shit-canning a number of defensive units on his way to the try line.
McKibbin is NOT running sweet. He had a few good weeks there, but last couple of games was back to jack shit. Foley has had a lot of game time lately and I can't help but think it might be worthwhile getting Berrick into a starting role to see if he's still on the page against fresh opposition. Therefore, what people are suggesting above i.e. a new halves combo, might be worth looking at. I think its time Grayson Hart got a go as well - real potential.
The pack should only have any changes required by injury, which is The Dwarf Ulugia for TPN. Holmes on the bench... ugh... I just threw up into my own mouth... I'd keep Ryan at THP under the obvious pressure there is to pick the other Wallaby THP.
The backline, besides the changes above, should not be screwed with. I wouldn't be moving Folau out of starting fullback now, just because its inconvenient in terms of Wallaby selection. Perhaps later in the game he can move out to blindside wing (in sweeper role).

Douglas may not be back of course, which would be a shame as he needs as much credit in the bank as possible, it would seem..
