‘Abhorrent content’: Carlton man charged with being propagandist for Islamic State

“The scale and dissemination placed this man as a principal distributor of ISIS propaganda within the group,” Hudson said. “The videos, photographs, audio files and documents contain messages relating to abhorrent content, being executions, mass murder, torture and propaganda,” Hudson said.

The material also included information on avoiding detection from law enforcement, and how-to guides on mass casualty attacks, she said. The accused allegedly distributed the material using an encrypted platform.

The man, who is an Australian citizen, has been charged with membership of a terrorism organisation, possessing and distributing extremist material and using a carriage service to cause offence.

Hudson did not rule out the possibility of making more arrests and said police were continuing to investigate individuals connected to the man.

“Viewing this violent extremist material is not harmless online content. It desensitises people and normalises violence. It radicalises people.”
