The business case for the east-west link toll road has not been submitted to Infrastructure Australia for scrutiny and has no prospect of getting the advisory authority's recommendation for federal funding this year.

The Napthine government's decision not to hand over requested information about the road project before a crucial June deadline has been interpreted as a snub of the authority, which was set up to take the politics out of funding major infrastructure projects.

Roads Minister Terry Mulder said in April that Infrastructure Australia had asked to see the east-west link business case before it completed its annual update of which major projects most deserve federal funding.

''They indicated they'd like it by June, we're doing some further work on that,'' Mr Mulder said.
