administrators report 19 March 2018, page-3

The report is written for creditors, not shareholders.
There is nothing left for shareholders except an empty shell.
The creditors may have courses of action to follow given that it was likely it was trading insolvently since around June 2017, but this will cost money which is not there.
As for the shareholders, a group would need to get together to launch a class action against the directors.
ASIC and ASX could also investigate for potential fraud but my guess is that won’t happen as it is a dead duck.
Realistically Zani should be barred from any future company directorship and should have his accountancy qualifications revoked.
This is just my opinion so others may see if differently.
