The research paper was conducted by Victoria University (VU) and was scheduled to release on Nov 2009.
According to The Australian, the paper will be now reviewed by the police in 60 days and will be released on Feb 16.
"The project was launched in Jun 2009 by the university as a 'fast-track attempt' to gather survey and interview evidence from students and community stakeholders," the report said.
The VU administration said that it was waiting for police approval as the participation of police was significant for a comprehensive and detailed report.
Senior Sergeant Simon Foster of the Victoria Police research coordinating committee said the 210-page report was too long and had to be reviewed by different areas of the organisation.
"When Victoria Police agrees to provide information, data or access to interview members for external research projects, they are given a 60-day period to review the draft report and provide feedback," he said.
