And I’m not sure if your comment about ‘And, the Aussie government has just relaxed the rules on using that money to purchase ‘geared’ investments (eg real-estate with an attached mortgage)!’ is correct, but think you might have the wrong end of the stick here. Most super money is held by superannuation companies that invest it in a variety of things, mostly the stock market, but also other assets (ie property and infrastructure).

It is possible to have what is called a ‘self-managed’ super fund where the individual invests the money themselves, but this is not very common, and comes with higher risk, a lot of fees and a hell of a lot of paperwork. Individuals who have their own self-managed super fund may invest in property, with additional mortgages, but as I said, it is not really very common.
