Ireland captain Brian O'Driscoll paid tribute to the tremendous Irish support after his side caused a World Cup shock by beating Australia 15-6 in Auckland today.
But he warned that only "half the job" was done as they now aim to top Pool C and potentially set up a quarter-final clash against Wales.
O'Driscoll told ITV1: "It's a performance we knew we had in us.
"We had to dig deeper than we had done in the last five games."
Ireland experienced an indifferent preparation for the World Cup, with some poor displays in their warm-up games.
But they displayed a fighting spirit and confidence against a well-fancied Australia side.
"It's half the job done," said O'Driscoll. "Two wins and two more to get. As much as we will enjoy this, let's not lose sight that we have two more games."
Ireland coach Declan Kidney refused to get carried away with the victory.
He said: "I was pleased with the way we went about out business.
"We managed to stifle a very good Australian side.
"I think our scrum is getting a little stronger. We still have a little bit of work to do. The work really starts now."
He did, however, add: "It's the fifth time we have played Australia in the Rugby World Cup and you get a bit fed up with losing."Reuse content
