Former Leinster flanker Rocky Elsom knows all about the atmosphere at Croke Park, and hopes his Australia team can adapt to the Gaelic stadium's ambience.
Elsom is Australia's captain for their current tour of the northern hemisphere, standing in for injured centre Stirling Mortlock.
A Heineken Cup winner with Leinster, he has fond memories of Dublin and will have the Wallabies well-primed for their first ever outing at Croke Park against the RBS 6 Nations winners.
"Croke Park is very different to Lansdowne Road,” said Elsom. “It's just so much bigger and there's a lot of people in the stands obviously, but the actual field itself is quite big.
"It's a much bigger playing field. It has a different feel about it as well.
"I don't know if overwhelming is the word but the fans certainly get stuck into it. You need to address the noise element because, compared to the crowds we get in Australia, it's very loud.
"I remember the Leinster-Munster match there, and the noise coming out of the place was deafening the whole game.
"If we were on the field together, we'd have to be so close and you'd have to be watching my mouth to hear what I was saying.
"We'll address that, but that's not too hard. You just need to make the players aware of it and we should be fine. Hopefully they don't make too much noise!"
