The government will on Tuesday release an ambitious target to raise the amount of visitor expenditure in Victoria to $36.5 billion in 2024-2025, up from $23.1 billion in 2014-15.

Attracting people from both Australia and overseas to regional Victoria will be central to growth.

A major push will be to capitalise on Asia's booming middle class by providing better infrastructure and tourism services for people from "emerging markets".

And while tourists are flocking to Melbourne, very few are staying overnight in regional Victoria – just 3 per cent of all overnight visitors to regional Victoria are international guests.

Tourism Minister John Eren said more five-star accommodation in regional areas was needed for high-yielding Asian tourists.

"If every visitor stayed one more night it is worth $2 billion to the economy," he said.

The Victorian Visitor Economy Strategy says just 10 per cent of Chinese and Indian visitors stay overnight in regional Victoria.

"Products, accommodation and infrastructure built in past decades may need renewal or updating to provide a more compelling experience for both domestic and those visitors from new markets," the paper says.

Visitor economy is a term that expands on traditional tourism to include visiting friends and family, business and medical travel and international education.

Currently Victorians make up 81 per cent of all overnight visits to regional Victorian, with another 16 per cent hailing from interstate.

"Encouraging Melburnians and Australians to travel to regional Victoria, in preference to other states or overseas, is a key growth opportunity for regional Victoria," the strategy paper says.

The government highlights many challenges outside of Melbourne including low awareness of regional tourism options in the Australian market, limited transport option for visitors, restricted internet access and limited accommodation options.

"While Victoria has significant natural attractions across the state, these are not as recognised in the domestic market as attractions in other states and territories.

"Many areas of regional Victoria also lack appropriate infrastructure, have difficulties attracting and retaining workers, and miss out on developments due to regulatory and information barriers."

Mr Eren said the government was looking at a number of ways to improve the sector including encouraging more private sector investment, improved branding and marketing and building better access into and around the state.
