Australia is the country most workers and retirees around the world would like to live in 20 years' time, an international survey found.

However, most Australians are unaware of how they will fund their retirement, the poll concluded.

The Retirement Scope survey conducted by French insurance giant AXA questioned workers from 26 countries, with two-thirds of Australian respondents unaware of the source of their retirement income or how much they would need.

Australians ranked as more aware than people from France, Spain or Indonesia, but behind those in Malaysia where more than half of workers can "put their finger on their retirement income", Fairfax newspapers report.

On the other hand, Australia's relaxed lifestyle and climate were its biggest attractions for retirees around the world, who voted it the most desirable place to retire to, although Australian respondents preferred New Zealand.

Australia came out above the United States and Switzerland.

The survey of 15,000 people found the average income of Australian retirees was $1,917 a month, while the cost of average household expenses is $1,437 a month.

"The survey found that the average retirement age among Australians is 57 years of age, and that 'old' is at 80 years, giving Australians 23 'bonus years' in which to enjoy a healthy and active retirement," AXA general manager of sales and marketing Adrian Emery told Fairfax.
