Victoria is demanding more than $6 billion extra from the Turnbull government for large projects, saying a severe funding imbalance is holding back the state economy.

Before the April 27 state budget, the May 3 federal budget and a probable July 2 federal election, the Andrews government has dramatically stepped up its demands for Commonwealth cash.

Victoria has long complained it is getting just 9 per cent of the national infrastructure carve-up – much less than its one-quarter share of the national population. Now it has put a figure on the size of the shortfall.

State Treasury analysis provided to Fairfax Media shows that for Victoria to receive its population share of infrastructure payments over the five years to 2018-19, the Turnbull government would need to hand over an extra $6.3 billion.
