An elected Labor government would invest $2 billion in the Melbourne Metro project, Bill Shorten has pledged, as part of a big pitch to win Victorian votes.

To date, the $11 billion rail tunnel project has been funded by the Andrews State Government, despite pleas to the Federal Coalition for a major contribution.

Mr Shorten has promised $2 billion in his first budget, which would allow Premier Daniel Andrews to fund other projects Victoria is planning.

Mr Andrews's thumping re-election victory last November was on the back of a strong infrastructure track record and agenda, including level crossing removals, Melbourne Metro and the North East Link.

Federal funding of infrastructure has been a sore point between Victoria and Canberra, with the Coalition putting aside money for the East West Link that Mr Andrews scrapped after winning the 2014 election.

"Federal Labor's investment will end nearly six years of cuts and chaos from the Liberals in Canberra, which has left the Andrews Labor Government to do all of the heavy lifting on infrastructure investment in Australia's fastest-growing state,'' Mr Shorten said.

"This investment means the Andrews Government will have a real partner in Canberra, so they can get on with delivering the pipeline of transport infrastructure that Victoria needs."

The Andrews Government has long argued that Victoria is being short-changed by the Federal Coalition, saying it has only received about 10 per cent of federal infrastructure cash, despite Victoria representing a quarter of Australia's population.

"Scott Morrison and the Liberals in Canberra are anti-public transport and anti-Victoria,'' Mr Shorten said.

Construction on the major project, including five underground stations, is well underway.

Victoria is a critical part of Mr Shorten's path to the Lodge, with consistent polling showing the state is the strongest for the ALP.

After last year's state election demolition, the party is eyeing off a swag of seats.

Melbourne Metro 'already funded'

Mr Morrison criticised Mr Shorten's promise to contribute money to a project that had already been funded by the state.

"All the states and territories I'm sure will be overjoyed to hear that if Bill Shorten's prime minister, he's basically going to come and give them more money to not build an extra thing," he said.

In the April Budget, the Coalition promised $2.1 billion to transport infrastructure in Victoria, to upgrade 13 arterial roads in Melbourne's suburbs, and upgrade rail infrastructure between South Geelong and Waurn Ponds in the marginal seat of Corangamite.

The Coalition has also said it would invest $2 billion for a fast train service between Melbourne and Geelong if the Victorian Government matched that investment, as well as promising billions to go towards a train to Melbourne Airport.

"You don't come and fund projects that are already funded, you come and commit to projects that actually expand what is being done in Victoria, that's what's happening with the Geelong to Melbourne fast rail, that's what's happening with the Melbourne Airport link," Mr Morrison said.

But the Labor Premier backed his federal counterpart's approach, as the majority of funding promised by the Coalition is not due to flow into the state until after 2023.

"What you've just seen Bill Shorten announce … that's what a real partnership looks like, a real partnership with a real project and real money — money provided over the next four years, not money that's on the never-never, for projects that haven't even been planned yet," he said.

Mr Morrison said his MPs across eastern Melbourne were still being told that the East West Link was a priority for their constituents.

"We stand absolutely by those Melburnians living in the eastern suburbs on Melbourne who want an East West Link," he said.
