Crystalise loss with ATO

Hello,

Is the announcement below sufficient to crystalise a loss as per ATO requirements?

Release Date: 21/11/23 19:14 Summary: Administration Update - Execution of DOCA

The announcement has the following text:

"However, shareholders should note that unfortunately, due to the administration of Tombola Gold, the value of its shares is niluntil such time as Goodsail repositions itself."

Or are you better to sell to delisted:
