Speaking ahead of a meeting with the country's treasurers in Canberra on Friday, Josh Frydenberg said he didn't support the push from NSW for such incentives.

But the Commonwealth would continue to partner with state governments to fund new infrastructure, he told Sky News.

"The Commonwealth's position is that the states don't need any financial incentives to recycle their assets," Mr Frydenberg told Sky.

"They've shown both a willingness and an ability to do that in the past."

The Council on Federal Financial Relations will see treasurers put their heads together to work on fast-tracking infrastructure projects across the country to boost the economy.

Mr Frydenberg also defended his decision to reject Queensland's request to have the Reserve Bank's deputy governor address the meeting on the effects of climate change on productivity.

He said there were other forums to raise those issues, and the Commonwealth wasn't interested in introducing new climate taxes as raised by other states.

Speaking on ABC Radio, Mr Frydenberg said a dinner on Thursday showed there was a "positive mood" among the gathered treasurers.

"There's an understanding that we need to put our political differences aside and get on with the job of serving our constituents," Mr Frydenberg said.

He told ABC's AM had agreed on "key areas" including road taxes for heavy vehicles, the NDIS and environmental approvals for projects.
