A BALLARAT man claimed to have had Australia's largest volume of child pornography material in his possession is facing jail.More than 900,000 items of child pornography was found in Stacy Livitsanis' possession after customs officials raided his home on July 3.They seized a laptop computer, three portable hard drives and a collection of CDs, DVDs, books and magazines from his house.Livitsanis was charged with two offences after an interview on July 3, but during another interview on September 15, he advised officials that he had bought a new laptop, which contained a number of child pornography stories.He pleaded guilty in December to eight child pornography-related charges, including importing child pornography, making child pornography and using a carriage or service to publish child pornography.Crown prosecutor Natasha Vicary yesterday told a plea hearing in the County Court at Ballarat that Livitsanis had an obsession with child pornography.She said he traded material to other people, wrote and published his own stories on the internet, received child pornography material through subscriptions and categorised the material on his computer."He has contributed to the on-going production of exploitation of these young girls,'' Ms Vicary said."All the images he downloaded were available to other users. There is no way to ascertain the amount he contributed to the movement of child pornography across the world."She said the volume of child pornography material found in Livitsanis' possession was one of the largest in Australia.The prosecution submitted that Livitsanis should be sentenced to three to five years' jail for the head sentence, with one to three years to be served.But defence barrister Tony Lavery urged for a non-immediate custodial sentence, submitting that his client had no prior criminal history and he had good prospects of rehabilitating.Judge Joe Gullaci adjourned the hearing until March 17.He remanded Livistanis in custody until then.
