The federal coalition will examine the detail of the prime minister's health and hospital plan before deciding whether to support it.
But opposition health spokesman Peter Dutton said it was already clear that Kevin Rudd had been unable to deliver a national agreement, with Western Australia failing to sign up.
"We'll see what they propose by way of legislation," he told reporters in Canberra on Tuesday.

Asking for details
Mr Dutton said the opposition could not support the reforms until all the details were on the table, adding there had been no national agreement reached.
"Legislation will have to include whatever agreement has been arrived at with Western Australia.
"Let's see if (Mr Rudd) gets agreement and let's see the legislation that follows."
July 1st deadline
Under the agreement, signed by all Labor state and territory leaders on Tuesday, additional money will begin flowing into the health system from July 1.
It remains unclear whether the flow of funds is contingent on WA Liberal Premier Colin Barnett signing up to the new system.
Mr Barnett supports most of the reform package but said he would not sign up to the agreement as is stands because of the component that would see the federal government claw back GST.
Premiers 'caved in'
Mr Dutton said other leaders had caved in to Mr Rudd.
"What it shows is that these premiers at the end of the day are still determined to feed their great health bureaucracies.
"Mr Rudd it seems is happy to extend a hand to help feed these bureaucracies in the future as well."
The pool of funds would be presided over by the states and territories.
"That's not health reform," Mr Dutton said, adding Mr Rudd had simply created a "great big new bureaucracy".
'Unanswered questions'
"In the analysis and the cold light of day, when people look at the detail of what Kevin Rudd is proposing, I suspect there's going to be some extra questions that the prime minister has not answered."
The coalition wanted health reform, Mr Dutton said.
"The Australian people want health reform, but we don't want Kevin Rudd's great big new bureaucracy."
