A Brisbane teacher has faced court over disturbing allegations that he groomed a child while running a child abuse website called “Foreskin Worship”.
Jonathan Graham Klupp, 58, was charged by Task Force ARGOS detectives earlier this month with a string of child abuse offences including administering the site, possessing or controlling child abuse material, and seven counts of using a carriage service to transmit, distribute, or make available child abuse material.
Court documents reveal the East Brisbane maths teacher is alleged to have administered child exploitation material website “Foreskin Worship” between February 1 and the date of his arrest, April 13.
Police allege Klupp used an anonymising service to avoid detection.
Klupp was given bail on his own undertaking, before being charged last Thursday with new offences including grooming and two counts of using a carriage service to solicit child abuse material, which allegedly occurred prior to his initial arrest.
Police allege Klupp groomed a child under 16 years between February 9 and March 22, with intent to facilitate the procurement of the child to engage in a sexual act outside Queensland, court documents reveal.
Klupp’s offences are all alleged to have occurred at his East Brisbane home.
Police searched Klupp’s home on the day of his arrest and seized multiple items allegedly linked to the possession and distribution of child exploitation material.
Police will allege that further forensic searches of his digital devices found Klupp engaging in inappropriate online behaviour with a child outside of Australia.
Crime Command Detective Acting Inspector Les Lucas said Argos investigators are committed to targeting alleged offenders involved in the sexual exploitation of children, and will use all available resources to detect and apprehend those who seek to exploit children in the community.
At the case’s first mention in, Klupp’s lawyer Lewis Hunter from Guest Lawyers requested that all the charges be adjourned for mention on May 15.
Klupp was granted bail on conditions including that he have no contact with children under 16, that he not attend any schools or playgrounds, and that he not use the internet aside from essential services.
He has not entered any pleas.
Klupp has worked in various leadership roles at private schools in the Brisbane area, including Prince of Peace at Everton Hills, where he worked as Head of Mathematics and Director of Students and Staff (Middle and Senior) until December 2025.
According to Klupp’s social media, he transitioned in January back to work at Faith Lutheran Redlands, where he had worked previously.
A spokesperson for Prince of Peace Everton Hills said the school was aware of an active police investigation involving a former staff member.
“Based on the information available to us, the College has no evidence that the matter relates to any current or past students,” the spokesperson said.
“As always, the safety and wellbeing of our students is our highest priority and we remain committed to providing a safe, respectful and supportive learning environment.”
A spokesperson for Faith Lutheran Redlands said they were aware of the police investigation, and confirmed Klupp is no longer employed by the school.
Investigations are ongoing.
