A University of Sydney study released this week found 43 per cent of regular pornography users were first introduced to explicit images between the age of 11 and 13.The study of 800 people, conducted through an internet survey, also found that about 47 per cent of participants spent between 30 minutes and three hours a day watching pornography; and that about 30 per cent acknowledged their work performance suffered due to excessive viewing.

Forensic Psychiatrist Dr Craig Raeside said the availability of porn to young people was a “big problem that is not being properly looked at”. Dr Raeside, who prepares psychiatric reports on many of the state’s most violent criminals, said he had seen youths spend up to four hours a night watching online porn, which often increased in its depravity as they became tolerant to the content.
