A judge in Cairns has retired to consider the verdict in a trial involving a teenager accused of participating in a violent home invasion in which a woman was sexually assaulted.

The three-day trial concluded in the Queensland Children's Court on Wednesday, 21 October 2026. The central legal question is whether the teenager knew that his co-offenders intended to rape the woman and whether his actions in detaining her partner helped enable the assaults.

The court has not yet delivered its verdict. The accused and victims cannot be identified for legal reasons.

What happened during the alleged home invasion? The court heard that three boys entered a home in Manunda, a suburb of Cairns, at approximately 3am on 21 February 2025.

The couple inside the property were reportedly woken by the intruders in their bedroom. Prosecutors alleged that while the teenager held the man at knifepoint, the other two offenders took the woman to different parts of the house and raped her multiple times.

The two co-offenders have pleaded guilty to rape, although their cases remain before the courts.

The teenager has pleaded guilty to six charges, including stealing, going armed in company and detaining the couple in their home. However, he has pleaded not guilty to five rape charges.

Why the teenager's knowledge matters The prosecution's case depends on whether the teenager heard one of the other offenders state an intention to sexually assault the woman.

The court heard evidence that the teenager was instructed to obtain a knife from the kitchen and keep the woman's partner detained in a room. Prosecutor Nicole Friedewald argued that preventing the partner from intervening helped enable the alleged assaults.

She submitted that a person can be held criminally responsible for an offence even without physically carrying it out, if the person's actions assisted or enabled it under the relevant provisions of Queensland's Criminal Code.

The prosecution also argued that the teenager could be responsible if he shared a common intention with the other offenders to carry out an unlawful purpose. What the defence argued Defence barrister Timothy Grau argued that his client did not intend to participate in a sexual assault. The defence maintained that the teenager believed the others were attempting to rob the couple and either did not hear or did not understand the alleged statement about rape.

The court also heard that the teenager believed he could be stabbed by his co-offenders if he refused to detain the man.

During a police interview played in court, the teenager said he had not known about the sexual assaults. When questioned about whether he tried to stop what happened to the woman, he said he had not.

The judge must assess this evidence and decide whether the prosecution has established the charges beyond reasonable doubt.

What happens next? Judge Joshua Treviño KC has retired to consider his verdict. The ABC reported that he intended to reach a decision as soon as possible.

The case raises important legal questions about the responsibility of people who allegedly assist serious crimes without directly committing every act themselves. However, the outcome will depend on the evidence and the law applicable to this particular case.
