Most Australians have multiple superannuation funds, and some people may not even be aware of all the funds they do have. Not only does this have the potential for multiple fees but it also makes it very hard to keep track on how the total superannuation balance is performing and also how level of life insurances, if any, you have.
The Australian Taxation Office assists in tracking down lost superannuation via their Super Seeker. Please access Super Seeker by clicking here.
Australia's Unclaimed Super Fund also offers a similar service which you can access here.
