An 18-year-old Queensland man has been charged with 30 offences following an investigation that began after authorities received information from the United States Federal Bureau of Investigation.

Queensland police allege the teenager operated several social media channels where material supporting violence against people from Muslim, Jewish and migrant backgrounds was shared.

The investigation led officers to execute a search warrant at a home in Warner, north-west of Brisbane, on 27 May 2026. Several electronic devices were seized during the search and subsequently examined by investigators.

Police allege the forensic examination identified files containing violent extremist material as well as material involving child abuse.

The teenager has been charged with multiple Commonwealth offences relating to the alleged transmission, promotion, solicitation and possession of violent extremist material through communications services. He is also charged with an offence relating to using a communications service to menace, harass or cause offence and one offence involving the alleged possession or control of child abuse material.

According to police, the charges include 14 counts of transmitting violent extremist material, eight counts of promoting violent extremist material, three counts of soliciting violent extremist material and three counts involving possession of violent extremist material through a communications service.

The investigation also resulted in a charge relating to allegedly possessing or controlling child abuse material obtained or accessed using a communications service.

The teenager first appeared before Pine Rivers Magistrates Court on 27 May and was remanded in custody. He is expected to return to court on Friday, 18 September 2026.

The investigation involved the Queensland Joint Counter Terrorism Team, which includes personnel from the Australian Federal Police, Queensland Police Service and Australian Security Intelligence Organisation.

Authorities said the investigation demonstrates the role of information sharing between international and Australian law-enforcement agencies when online activity raises concerns about potential threats.

Police have not alleged that the teenager carried out a physical attack. The charges relate to alleged online activity and material located during the investigation.

The case is now before the courts, where the allegations will be tested through the legal process. The accused is presumed innocent unless proven guilty.

The investigation also highlights the increasing focus by Australian authorities on online material that allegedly promotes violence or extremist ideology.

Authorities continue to encourage people to report information that may indicate a potential national-security threat, while emphasising that concerns should be assessed by appropriate law-enforcement agencies.

The teenager's next court appearance is expected to provide the next stage in the legal proceedings.
