Adam Ashley-Cooper insists that Australia will not get ahead of themselves after dumping England out of the World Cup and emphatically underlining their title credentials.
The Wallabies return to Twickenham next Saturday for a Pool A decider against Wales. The winners are likely to secure a last-eight clash against Scotland or Japan, while the losers face a probable appointment with South Africa.
"In every game we play we build on that self-belief. There is a lot of it in the team, but we haven't won anything yet," Wallabies wing Ashley-Cooper said. "It is very much just doing your own role moment by moment, knowing what your role is and winning those individual battles.
"We are gaining a lot of confidence with the wins, but we don't want to get too far ahead of ourselves. We have got a big Test match against Wales coming up, and then a quarter-final after that. We all want to be world champions and it is a matter of improving each day.
Wales have lost their 10 Tests against Australia - seven of those defeats were by six points or less - which suggests the Wallabies have a clear edge going into next Saturday's encounter.
Ashley-Cooper added: "We have had a good run against Wales, but anything can happen. A lot of results in this tournament have proved that. We have been saying all year about being consistent. At the moment we are a good team, but we want to be a great team."
