Queensland Police have charged an 18-year-old man from South Gladstone following a counter-terrorism investigation that began after authorities received information through Australia's National Security Hotline.

The investigation was launched after a member of the public contacted the hotline on Friday, 6 November 2026, raising concerns about possible plans involving violent activities. The information was passed to the relevant authorities, prompting detectives from the Queensland Police Service's Counter-Terrorism Investigation Group to begin inquiries.

Police allege that the teenager was making plans to carry out acts of violence. Following the initial report, investigators examined the available information and took action to prevent any potential threat from developing.

The 18-year-old was arrested on Friday and subsequently charged with one count of planning to cause death or grievous bodily harm. This is a serious criminal allegation involving suspected preparations for violence.

Following the arrest, police opposed the man's release on bail. He was scheduled to appear before Gladstone Magistrates Court on Saturday, 7 November 2026, where the matter was expected to enter the court process.

Queensland Police have reassured residents that there are no known ongoing direct threats to the community or any upcoming events connected with the investigation. Authorities said they continue to work closely with federal and state agencies to maintain public safety.

The case highlights the importance of public reporting in identifying potential security concerns. The National Security Hotline allows members of the public to share information that may assist authorities in identifying threats before violence occurs.

Police have encouraged anyone who notices suspicious behaviour or has information about possible threats to contact the appropriate authorities. Even information that initially appears minor may help investigators assess a situation and determine whether further action is required.

The National Security Hotline can be contacted on 1800 123 400. People can also provide information directly to Queensland Police or Crime Stoppers.

Authorities have not publicly established that an attack was carried out, and the allegations against the accused man remain before the legal process. The investigation demonstrates the role of cooperation between the public and law enforcement agencies in responding to potential national security concerns.
