Local households could face an extra $435 rate charge each to help underwrite a proposed new $19 billion train tunnel that would connect Clifton Hill with Newport , the state's key infrastructure adviser says.

In a report released on Thursday, Infrastructure Victoria concluded that the Melbourne Metro 2 project - a proposed train tunnel running from Clifton Hill to Newport via Parkville, Southern Cross Station and Fishermans Bend - could add about $20 billion to land values.

It warned that residential and commercial properties set to benefit from big infrastructure projects might need to get used to the idea of helping pay for them.

In a controversial approach to funding infrastructure known as "value capture", and which is championed by Prime Minister Malcolm Turnbull, it concluded about one-quarter of the project costs could be funded by hitting those who benefit with a "betterment levy".
