Bringing forward infrastructure spending to pump more money into the economy is on Josh Frydenberg's agenda - but he says the states haven't come through with ideas yet.
The latest economic data says the Australian economy is struggling and needs stimulus, with the Reserve Bank calling for the federal government to bring forward spending.
The treasurer met with his state and territory counterparts on Friday to check in after the prime minister wrote to them asking for projects that could be brought forward.
"We have received a letter back from Queensland but we haven't received a letter back from the other states and territories," Mr Frydenberg told reporters in Canberra.
"We will look at those suggestions on a case-by-case basis and clearly, there are some capacity constraints in some of the larger economies, namely in New South Wales and Victoria."
Mr Frydenberg said he spoke to the states about using smaller construction firms to do maintenance work so the pipeline of infrastructure spending continues, even as the big firms are busy with other work.
The states and territories have also agreed to a national population framework, which will show where people are living and where infrastructure needs to be built.
"It agreed that we would have better data-sharing. It also agreed we would have better forecasting, common forecasting, across the nation," Population Minister Alan Tudge told reporters.
Mr Frydenberg did rule out reviving the asset recycling fund, in which the federal government gave states money if they sold off assets.
"The Commonwealth's position is that the states don't need any financial incentives to recycle their assets," he told Sky News ahead of the meeting.
"They've shown both a willingness and an ability to do that in the past."
The Reserve Bank has called for more infrastructure spending to lift the flagging economy and has indicated it is prepared to cut rates to another record low in coming months if things don't improve.
But Finance Minister Mathias Cormann doesn't expect the Reserve Bank to use quantitative easing - buying up debt to pump money into the economy - to get cash flowing.
"It's not something that the political level of government should be interfering with," he told Sky News.
Labor shadow treasurer Jim Chalmers said the coalition was letting the economy flounder rather than taking active steps to keep it growing.
"If the treasurer was doing his job, then the states wouldn't be piling on the pressure to bring forward infrastructure spending," he told reporters in Melbourne.
