Administrators Report, page-90

Basically wrote the shares off as zero. No chance of getting anything for them. Similar principal used if you were to ever have a asset lost or destroyed and the value is written down to zero.

If and when it does relist (i highly doubt it seeing the light of day again) i would then need to declare it as income in the financial year when i sell.Paying tax on a entire lot as my cost base will be effectively zero. basically i've crystallized my loss. 

My situation is a bit diff as i day trade a bit and im classified as running a business enterprise with my day trading. So all profits and losses are taxed accordingly and im not entitled to the cgt discount if i was a 'investor".

This is not fin advice and you should seek independent advice.
