SA music school founder sent to jail

The founder of a children's music school in Adelaide who claimed he was drawn to "bizarre, confronting and unusual" pornography has been jailed for accessing child exploitation material while on a bond for similar offences.

Lee James, 45, pleaded guilty to multiple child pornography offences after police discovered in March that he had been using the social media app Kik to exchange child exploitation material.

In the SA District Court on Friday, Judge Paul Slattery jailed James for at least 11 months, describing the material he had accessed as "very disturbing".

The court heard James, the founder of Wilunga's Academy of Rock music school, was convicted in November 2014 of possessing child pornography but spared jail and banned from using the internet.

Just months later James admitted receiving child pornography images from another man on Kik.

He also used the app to send the man a detailed description of fictional sex acts between children.

The court heard James was isolated, lonely and suffering from anxiety when he re-offended after being separated from his wife and children, losing his business and being cast out of his Pentecostal church.

His lawyers claimed he went along with the other Kik user's fantasies because he was vulnerable and seeking companionship.

But Judge Slattery rejected a defence submission that James, whom he described as having a longstanding pornography addiction, was not specifically attracted to children.

"You say (instead) that you are drawn to pornography which is bizarre, confronting and unusual," he said.

"I am unable to accept that submission as your offending is in no way isolated."

He sentenced James to 23 months, three weeks and three days in prison, taking into account time owed for his previous offences.
