When you first start working you often move between a number of different jobs. With each job comes more paperwork - forms for tax and bank detials and bunch of stuff that you probably don't care about.

When it comes to super, it seems much easier to sign up a new fund than track down your membership number from your previous account. Down the track you could've signed up for a stack of different super funds and forgotten about most of the money you'd accumulated. That money could be part of the $10 billion.

Some people reckon they wouldn't have a lot in their lost super, but if you dropped $20 down the back of the couch, you'd look for it, right? So why not do a free search for you lost super?

It's easy to find your lost super. And it's free. All you have to do is check out www.unclaimedsuper.com.au or visit the ATO's website www.ato.gov.au/super and do a superseeker search. You can also call the ATO Lost Members Register on 13 10 20.

And finding your super can also be fun. AUSfund, the Australian Unclaimed Super Fund, has launched an online game starring the cartoon character Supermutt to make searching for lost super fun. See how much lost super you can find at www.lostsuperaustralia.com
