Skipper McGrath wants Ireland out of blocks quickly against Aussies
The Aussies are the last of the major rugby nations Ireland will play as this tournament enters its sixth year and McGrath, one of just two survivors from last year, hopes they can repeat their opening day win when they ousted hosts South Africa 12 months ago.
McGrath, along with his fellow UCD and Leinster flanker colleague Josh van der Flier, are the only players to have experience of this tournament.
