Victoria's privacy watchdog has reportedly apologised for mistakenly releasing the email addresses of more than 300 people.
Radio station 3AW has reported the addresses were revealed when an invitation was sent out for an information security forum.

Those on the list reportedly included Emergency Services Commissioner Craig Lapsley and EPA Environment Protection Authority boss Nial Finegan.
Privacy Commissioner David Watts said most addresses on the list were internal government emails, according to 3AW.
Fairfax Media has contacted the Privacy Commissioner for comment.
The bungle comes at a sensitive time for the commissioner as the Andrews government moves to merge his office with the Office of the Freedom of Information Commissioner.
Mr Watts has previously criticised the looming merger and accused the Community and Public Sector Union of attempting to have him sacked.
The commissioner's job is considered vulnerable once the merger is complete.
Despite Mr Watts' public criticism, the government insisted it was "streamlining" Victoria's information and data oversight bodies with the merger.
Last year Mr Watts slammed the restructure, telling iTnews he wanted nothing to do with it and would quit rather than be part of the changes.
The controversy deepened earlier this month when Opposition spokesman Gordon Rich-Phillips accused the government of mounting an attack on the commissioner's office.
Mr Watts also recently wrote to Premier Daniel Andrews expressing concerns about an attempt to audit the phones of ministers to trace the source of a leak.
