Australian workers have an average of $50,000 worth of managed investments and super savings, according to the AFG Global Funds Management Index.
The figure ranks Australia as number one in the Index's Managed Funds per capita table. In comparison, the average balance in managed funds per American was $40,000.
The US, however, does not have a mandated super environment.
According to the index, Australia's managed funds per capita have increased by 114 per cent since 2001.
Investment and Financial Services Association deputy chief executive John O'Shaughnessy identified the strong investment performance of the local market as well as both the mandated nine per cent super contribution and voluntary savings as key factors behind this growth.
He said the voluntary savings driven by government incentives such as the co-contribution, the abolishment of the contributions surcharge and changes in taxation for the over 60 year olds have all helped increase inflows into super and non-super investment products.
