UNDERGROUND

Many in the underground felt duped by Gill, but they weren’t the only ones. Soon some journalists and police would feel the same way. Stuart Gill wasn’t even his real name.

What Gill really wanted, some citizens in the underground came to believe, was a public platform from which he could whip up hacker hype and then demand the introduction of tough new anti-hacking laws.

After that, he was transferred to the Internal Investigations Department (IID), where he worked with Cosgriff who joined IID in 1988.

Over a six-month period in 1992, Tony Warren received more than 200 phone calls from Stuart Gill - 45 of them to his home number. Over an eighteen-month period in 1991–92, Chris Cosgriff made at least 76 personal visits to Gill’s home address and recorded 316 phone calls with him.²

If you had access to ISU, you knew everything that the Victoria Police officially knew about cor- ruption within its ranks. Its information was highly sensitive, particularly since it could involve one police officer dobbing in another. However, a 1993 Victorian Ombudsman’s report concluded that Cosgriff leaked a large amount of confidential
