Skipper Peter O'Mahony has called on his Ireland team to tighten up their discipline as they aim to level the Test series against Australia with a win in Melbourne (11.05am).
Joe Schmidt's side pride themselves on their discipline and are unhappy with the 10 penalties they conceded last week.
Ireland will look to turn around last week's 18-9 defeat and O'Mahony said discipline has been a particular focus.
"It's an area that is very important to us. Ten penalties is considerably more than we give away as an average. We've spoken about it," the captain said.
"The less access you give to a team like Australia the better. You saw with 10 penalties last week, you're going to struggle a bit.
"There was a bit of hurt but there was a real hunger to get back out on the training pitch, so that was something that would give you confidence."
