Visitors from China are heading to destinations including the Gold Coast and Tropical North Queensland in growing numbers, according to a report.

They are also spending more time in regional areas of Australia than the international visitor average.

The Deloitte Tourism and Hotel Market Outlook predicted that in little more than 20 years the number of Chinese tourists to Australia could parallel our entire international tourism market today.

More than two thirds of growth in the next three years will come from Asia, mostly from China.

"We've known for some time that China is where the growth is and where the biggest opportunity is but until recently it's been quite focused on the gateway cities,'' Deloitte Access Economics director Lachlan Smirl said.

"Some of the other regions are starting to share the benefits of this rapidly growing market."

Mr Smirl said Queensland had benefited from Chinese airlines flying to Cairns and improving transport to other regional areas could help spread tourists further.

While the falling Australian dollar may make the destination more appealing for international tourists, Mr Smirl said the growth in income and the rising Chinese middle-class in particular was a bigger factor.
