Ann: Declaration - no dividend to shareholders or options holders, page-5

From the ato website

You may be able to realise a capital loss on worthless shares before a company is dissolved if a liquidator or administrator declares in writing that there is no likelihood you will receive any further distribution in the course of winding up a company.

My understanding is that this ann serves as the declaration referred to above and that you can claim your loss this eofy.
Probably worthwhile taking a copy of this ann to your accountant and confirm with them.
