Seems a sensible enough selection. It isn't a game that lends itself to experimentation.
New players need to be transitioned in without risking them getting any confidence set backs.
You have to give the benefit of the doubt to the last team that lined out also.
Ireland's best hope is to keep it hoofed at the Aussies all day and hope they make mistakes in their own territory.
It might also discourage them from committing lots of players close to the advantage line.
Maybe try and turn it into a penalty kicking competition, as I can't see Ireland breaking through Aussies lines easily.
From 9 to 15, Ireland have decent kickers, so we might as well use them.
