Thanks cutty. I have heard of this service from delisted.com.au but have yet to use them.

I've also heard another option where you can use the company's announcement of going into administration as proof that the shares are worthless and thus allowing you to use the loss as a tax offset. Can anyone shed some light on this?

There are documents on asx.com.au that show the company is in administration.
