Instead, there was a list of 10 topics of consensus and eight priority areas where the government will seek to move quickly on reform, with Chalmers saying “a lot of the hard work begins now”.

One of those areas is a road user charge, which Chalmers said “there was a lot of conceptual support for”.

While a final model hasn’t been settled on, state and territory treasurers will be presented with a list of potential options on September 5.

“Right around the table, people had a view that this is an idea whose time has come and so we will do that work,” Chalmers said.

“It does, I think, encourage us down that path. But as you know, this is something we’ve been working on for a little while as well.

“We’ve got some good views, some good input. We’ll work with the states and territories to try and work out the best model on the best timing.”

It’s needed by the federal budget to make up for declining fuel excise revenue due to Australians increasingly shifting to hybrid and electric vehicles.

While many of the proposals flagged by economists and think tanks prior to the roundtable focused on tax reform, no consensus on the issue was reached during this week’s meeting.

Instead, Chalmers said the government would continue talks with the experts invited to the summit about taxation.

When asked about former Treasury secretary Ken Henry’s characterisation of the tax system as “intergenerational bastardry” that treats younger Australians unfairly, the treasurer acknowledged work needed to be done.

“Our tax system is imperfect and one of its most troubling imperfections is best seen through an inter-generational lens,” Chalmers said.

“Almost everybody around the table had a similar view, which is we take our responsibilities to the coming generations seriously.

“We recognise that we, as people of influence, with this opportunity have responsibilities in lots of ways, but especially inter-generational responsibilities and we take them very seriously.”
