How to change Share Holding Details

I have moved addresses and would like to update my contact details for my CSD shares in the off chance that this comes back to life (Hope springs eternal).
Does any one know how to do this, I have looked on automic.com.au but cannot find anyway to do this plus all my shares have been removed and are listed as "CHESS to Issuer Sponsored conversion".
I am assuming that this means that CSD have there own registry??

If anyone can let me know where to go or who to email that would be greatly appreciated.

Thanks
