Star striker Tim Cahill declared that the Socceroos will stop at nothing in their bid to become Asian champions after an impressive 4-0 victory over Oman at Stadium Australia.
"We want to go for it," an exuberant Cahill said later. "We've been working on making ourselves that little bit better than all the other teams."
Cahill captained the Socceroos to a comprehensive victory that catapulted the side into the quarter-finals.
Ange Postecogou's men need only a draw in the final group match against Korea Republic in Brisbane on Saturday to win Group A.
"It's been a very proud day for me," said Cahill who wore the armband after regular skipper Mile Jedinak was ruled out with an ankle injury.
"I feel it's great that the boys, the manager and staff can reward themselves with a top performance.
"This is the result of months and months of football and I've always believed that this side has lots of goals in it. There is a lot of depth in this team. A lot of people were questioning the changes.
"But the boss knows what he's doing and best of all the players know that it is going to take the 23 of us to win games."
Cahill said he believed in the team's all-round ability to meet the Asian Cup challenge.
"I really believe in these boys," he said.
"After the first game when I looked at the analysis everybody was talking about the goals we conceded.
"People were saying we were going to have a tough test today. So what is the analysis going to be now?
"We will take every game at a time but I feel that against Korea, even though we have qualified for the quarter-finals, we are not going to rest.
"We want maximum points, we want to keep winning games and we want to make an impact.
"We love this football and we love this style that we're playing.
"They could not deal with the waves of pressure and our fitness. That was supposed to be a tough test."
Cahill has scored the bulk of Australia's goals since Postecoglou took over the national coach job 14 months ago.
He was pleased to note that the eight goals Australia has scored in this tournament have come from eight players.
"I believe in these players," he said when it was suggested to him that he can breathe a little easier in the knowledge that he does not have to save Australia every game.
"The thing is that they have to believe in themselves. And they do. The key now is consistency. How do we drive them to be consistent and make them as professional as possible."
Mark Bresciano, who came on for Massimo Luongo after 50 minutes, shared Cahill's optimism.
"We saw from the first minute when we took the game to them and put them under pressure," Bresciano said.
"We did not really give them a chance.
"We're seeing the confidence and belief coming through now.
"Ever player who has played, whether starting or coming off the bench, has made an impact."
