Australia is one of the top five pension markets in the world, thanks to compulsory superannuation.
The latest Towers Watson global pension assets study shows Australian superannuation assets relative to GDP rose to 101% last year.
Only the United States, Britain, Switzerland and Netherlands are up at those levels.
Radio New Zealand's Sydney correspondent reports the other remarkable fact is that Australians have a bigger exposure to shares than most other countries - 52%, compared to a global average of 47% and closer to 30% in Europe.
Australia (population 20 million) also has the highest allocation to cash at 8% and are second only to the Swiss in their investment in alternative assets.
