The survey of more than 2700 people nationally showed that 82 per cent of the respondents want a train connecting the two points every 10 minutes, with travel time between the two slashed to 20 minutes.

The Victorian government in November unveiled a $50 billion suburban rail loop plan that will connect to an airport rail.

"The Melbourne Airport rail link needs to be a dedicated service and not be part of the suburban rail network which is already at capacity and subject to delays across the commuter network," TTF chief executive Margy Osmond said.

"This is game-changing infrastructure and a once in a generation opportunity that Victoria must get right."

"As Melbourne's status as a global tourism destination continues to grow, this is such an important opportunity to show the city is truly world-class," Ms Osmond said.

A record 37.3 million people travelled through Melbourne airport in the 2018/19 financial year.

Currently, passengers' use taxis, buses and rideshare services to get to and from the airport.

Uber announced in June that Melbourne would be the third city in the world to test Uber Air flights to connect the city to the airport.

"Tourism's economic contribution to Victoria is expected to grow to $36 billion a year by 2026," Victoria Tourism Industry Council chief executive Felicia Mariani said.

"With more people choosing Melbourne as their holiday destination, we must deliver world-class transport to meet the demands of today's global traveller."
