I don't think it exists. In all likelihood, the comment on the ATSB site is still valid:
"The investigation by the Italian authorities is continuing. The ATSB has completed its contribution to the Italian investigation and plans to publish a copy of the final report on the ATSB website
Australian Transport Safety Bureau (ATSB) when it is received from the Italian authorities."
It's by no means the only accident from many years ago that is still technically "under investigation" by the ANSV.
