Ireland captain Brian O'Driscoll celebrated his first Rugby World Cup win over Australia on Saturday night, but warned that the job was "only half-done."
The Irish now aim to finish as Pool C winners and potentially set up a quarter-final clash against Wales.
''It is a performance we knew we had in us. We had to dig deeper than we had done in the last five games," said the skipper after Ireland's 15-6 victory.
''We will enjoy this, but let's not forget that we have two more games.''
Coach Declan Kidney also refused to get carried away with the victory.
However, he added: ''It's the fifth time we have played Australia in the Rugby World Cup and you get a bit fed up with losing.''
Ireland next play Russia on 25 September and Italy on 2 October.
