Instead of tweeting about public transport Prime Minister Malcolm Turnbull should fund it, the Victorian premier says.
The state has asked for $4.5 billion in federal money for the Melbourne Metro Rail project, which Premier Daniel Andrews promised at the election was fully costed and fully funded.
The federal government is examining the business case for the $10.9 billion rail tunnel, but that didn't stop Mr Andrews throwing a few jabs at Canberra on Tuesday.
"We would like a partnership with the Commonwealth government (but) if their interest in public transport doesn't extend beyond riding trams and tweeting about it, well fine," the premier told reporters.
"But the Victorian community will judge them accordingly."

Mr Turnbull famously tweeted pictures from his train trips as his challenge to former prime minister Tony Abbott gained pace.
Mr Andrews told 3AW that Victoria will go it alone if the federal government doesn't back the project.
"Look, the thing is this, we'll get on and do this whether it's with Mr Turnbull or not," he said.
Victorian Treasurer Tim Pallas last week flagged the state would take on new debt to fund infrastructure.
Shadow treasurer Michael O'Brien said Mr Andrews was playing catch-up after over-promising.
"Before the election Daniel Andrews said all his policies were fully funded and properly costed," Mr O'Brien told AAP.
"Now we discover that they were unfunded and badly costed and he wants Malcolm Turnbull to make up the shortfall."
The Melbourne Metro Rail project will build five new stations and put twin tunnels under the CBD.
