Australia skipper Ricky Ponting said his side were "on target" to retain their World Cup title after their huge victory over New Zealand in Grenada.
Ponting scored 66 against the Black Caps in Grenada
Australia play South Africa in the semi-finals in Jamaica on Wednesday.
"We're very confident, we're playing excellent cricket and we're going to take a lot of beating in that semi-final," said Ponting.
"Matthew Hayden is in the form of his career and Shane Watson, in his first innings in a while, was magnificent."
Ponting added: "Once again the batting was terrific. We had some great partnerships at the top of the order and that allowed the guys at the bottom of the innings to smack it about a bit."
Hayden, who hit 103 for his third hundred of the tournament, was dropped from the team last year before fighting his way back into contention.
So the powerful left-hander is refusing to get carried away by his current success.
"We have two more matches to go and it all will mean zero if we don't go all the way," he said.
"I have put in a lot of work to get back in the side. You need a lot of dedication to be part of this team. I'm very proud of what I've achieved."
Ponting was particularly pleased with Watson, who returned to the team after missing two matches because of a calf strain, having missed the entire Ashes series due to hamstring trouble.
"Shane Watson is a very, very good and very, very talented cricketer, someone that works extremely hard at his game," he enthused.
"He hasn't had a great run with injuries but if you look at his form in the one-day team over the last couple of years he has hardly put a foot wrong."
