As long as we win it, no! I dont subscribe to the idea that there are players fighting for a starting position against the Orcs.
Its as its always been, just concentrate on winning each game, starting in this pool really meant Australia always had to approach it as if the pool games were already over, it was sudden death from the get go.
I reckon that is the approach Cheika has taken with the 31 and his game management of those players. Dont forget although we have the chance to run a different 23 against Uruguay, before the Orc's game, we then have the Wales game straight after that. So its two games against top teams fighting for survival, in one week - that we will need our best 23 for. Its improbable that the Wobblies would get through both those games unscathed with some sort of injury.
Then its straight into 1/4 finals 7 days later.
Just need to keep winning!
