Irish will be on best behaviour, vows Peter O’Mahony

Ireland captain Peter O’Mahony has echoed head coach Joe Schmidt’s calls for better discipline when the Six Nations champions meet Australia.

Ireland trail 1-0 in the three-Test series and must win today’s game, at AAMI Park, to stay alive in the contest, but to do so must reduce a penalty count that edged into double figures in Brisbane last Saturday.

Australia won the series opener 18-9 at Suncorp Stadium. Ireland conceded 10 penalties, having notched 12 in beating England at Twickenham to win the Grand Slam on March 17. They have been in single figures in each of their seven other Tests this season.
