The prime minister has joined Premier Denis Napthine on the campaign trail in Victoria, declaring that the state election is a referendum on infrastructure.
Describing himself as "the infrastructure prime minister standing beside the infrastructure premier", Tony Abbott said only Dr Napthine's re-election would secure the East West Link road that Melbourne needs.
"It is a referendum on the East West Link," Mr Abbott said as he and Dr Napthine announced further upgrades to the Tullamarine Freeway.
"It is a referendum on the plan that this premier has and no-one else has, to build a modern 21st century city with 21st century infrastructure."
Dr Napthine said there were a number of infrastructure projects that would be key to winning the election, but the vote would come down to who could be trusted to deliver.
"This election is about who you can trust to keep our finances safe, who you can trust to deliver key infrastructure that makes a real difference to the people of Victoria."
The federal government will commit $200 million to the $250 million expansion of the Tullamarine Freeway project if the Napthine government is re-elected, Mr Abbott said.
Opposition leader Daniel Andrews said Labor had been clear on their transport priorities.
He said a Melbourne metro system, double the size of the city loop, was key to the city's future, along with getting rid of the 50 most dangerous and congested level crossings.
"They are our priorities, absolutely. And we will deliver on them in full."
Mr Andrews visited St Kilda's Junction Oval to pledge a $25 million upgrade to cricket grandstands, change rooms and high-performance training areas.
"It's what's needed for the game, it's what's needed for all the jobs, the visitor economy, the tourism benefits that come from more international games being played here," Mr Andrews said.
