Background
The applicant, a child, was charged with two offences following his arrest on 28 May 2026 when he attended a petrol station armed with a knife and threatened to stab an employee. Upon arrest, he disclosed to police that he had wanted to kill people for months, was inspired by school shooters and mass murderers, and had attempted to steal a vehicle to travel to a primary school to murder children he perceived as “easy targets.” Following police searches, investigators discovered he possessed video footage of the Christchurch massacre, had accessed manifestos from mass casualty offenders, held neo-Nazi white supremacy views, and had attempted to source firearms via the dark web.
The charges brought were: (1) under section 540A(1) of the Criminal Code (Qld), doing any act in preparation for an offence likely to cause death of another person (April–May 2026); and (2) under section 474.45C(1) of the Criminal Code 1995 (Cth), possession of violent extremist material obtained via carriage service. A magistrate at Maryborough denied bail. The applicant sought review as a hearing de novo under section 19B of the Bail Act 1980 (Qld). At the time of the Supreme Court hearing, the applicant was detained in Children’s Hospital Brisbane under involuntary mental health treatment.
The applicant’s counsel argued the charges reflected merely “dark thoughts” with no communication to others, and contended that further prosecution was an abuse of process because the applicant had previously been cautioned for related offences (going armed, making threats, attempting to enter premises with intent) under the Youth Justice Act 1992 (Qld).
The Court’s Holding
Justice Davis dismissed the application and upheld the detention. The court found an unacceptable risk that the applicant would commit an offence endangering the community or safety of a person, and that no bail conditions could adequately mitigate that risk under section 48AAA(2) of the Youth Justice Act.
On the abuse of process argument, the court ruled the new charges under section 540A and section 474.45C had fundamentally different elements from the offences for which the applicant had been cautioned, and thus did not constitute double jeopardy. The double jeopardy question could be resolved fully during prosecution. On the “dark thoughts” defense, the court rejected the argument that thoughts alone cannot form the basis of criminal liability, noting that section 540A—introduced in the wake of the Bondi Shootings in December 2025—specifically requires only “any act in preparation for” an offence, not execution or communication to third parties. The applicant’s documented acts (creating a manifesto titled “The Albert Massacre” referencing a local school, prompting AI to generate mass shooting narratives, compiling violent extremist videos, accessing dark web weapons suppliers, making threats to kill his mother) constituted sufficient preparatory acts demonstrating genuine and imminent danger.
The court recognized that although the applicant was currently detained at Children’s Hospital Brisbane, bail would not secure release, but detention remained warranted given the demonstrated ideological commitment and objective danger posed by the child.
Key Takeaways
- Section 540A (the new Queensland preparation offence) can be satisfied without proof the defendant communicated threats or intentions to others; internal manifestos, online prompts, and accumulated violent material suffice to establish preparatory acts.
- Courts will detain children under section 48AAA(2) Youth Justice Act where evidence shows ideological radicalization, sustained interest in mass violence, and accumulation of operational resources (manifestos, extremist videos, dark web weapons sourcing), even absent an imminent specific attack plan.
- Bail conditions cannot mitigate the risk posed by ideologically motivated children who have demonstrated sustained intent to commit mass violence; detention is mandatory where no conditions render the risk acceptable.
- Caution under Youth Justice Act for related offences (going armed, threats) does not bar prosecution for distinct preparation/possession offences with different statutory elements.
Why It Matters
This decision provides the first judicial interpretation of Queensland’s new section 540A offence, establishing that it operates as a genuine inchoate crime capturing acts far upstream of attempt, aimed at radical ideological violence before operational specificity crystallizes. The ruling signals that courts will treat accumulation of extremist material, manifestos, and weapons-sourcing activity as actionable preparatory conduct sufficient to trigger preventive detention of minors, even absent a fixed target or imminent timeline. For child defendants, section 48AAA(2) mandates detention where the risk cannot be conditioned away—a high bar that this case illustrates applies when ideology and accumulated preparation evidence converge.
The decision also clarifies the interplay between the new Queensland preparation offence and the longstanding federal offence of possessing violent extremist material (section 474.45C(1) Crimes Act 1995 (Cth)), indicating prosecutors can charge both to reach conduct that reflects sustained ideological commitment. Courts worldwide considering comparable legislation will note that the bar for denying bail to a child in such cases is whether *any* conditions could work—not whether release is probable or whether the child is currently detained elsewhere on mental health grounds.
