TL;DR: Former disability support worker Adam Mason has been sentenced to nine months in prison and a two-year community corrections order for sexually assaulting two vulnerable clients. The case highlights severe breaches of trust within the NDIS provider system and the psychological impact of abuse on individuals with cognitive impairments.
Chronology of the Offending and Breach of Trust
Adam Mason, 31, was employed as a disability support worker when he committed a series of sexual offenses against two vulnerable women in his care. Mason began working as a support worker in 2022 and was assigned to his first victim in October of that year. By their third appointment, Mason began crossing professional boundaries, telling the client he "liked her a lot," giving her hugs, purchasing personal gifts, and kissing her for the first time in December 2022.
In January 2023, the professional relationship deteriorated further when the pair engaged in a sexual encounter. Recognizing the breach, Mason recorded in his employer's communication system that the client had developed feelings for him, and advised that he needed to stop acting as her carer. Although another support worker was assigned to the client, Mason continued to meet with the woman in secret, engaging in two additional sexual encounters.
The relationship was disclosed in March 2023 when the first victim informed her new support worker about the situation, noting they had recently had an argument and expressing concern that Mason was seeing another one of his clients. Following this disclosure, Mason was suspended. Shortly thereafter, a second vulnerable client came forward, disclosing that Mason had kissed her during a session that same month, an action that she stated had "caused her to freak out."
Legal Proceedings and Sentencing
On August 12, 2026, Mason appeared in the County Court of Victoria in Melbourne for sentencing. He pleaded guilty to three counts of sexually penetrating a person with a cognitive impairment or mental disorder, and two counts of sexually assaulting a person with a cognitive impairment or mental disorder.
Presiding Judge Nola Karapanagiotidis sentenced Mason to nine months in prison, to be followed by a two-year community corrections order. As part of this order, Mason is required to undergo mandatory mental health treatment and perform 80 hours of unpaid community service. In delivering her sentencing remarks, Judge Karapanagiotidis described the offenses as "inherently serious," stating that Mason had directly breached the profound trust placed in him and offended against two highly vulnerable women.
During a police interview conducted in 2024, Mason admitted to the actions, describing his decision to kiss the second victim as a "weak moment" and acknowledging that while he knew he should not have entered into a relationship with the first victim, he had "fallen in love with her." The court accepted that Mason was remorseful and determined that his prospects for long-term rehabilitation were favorable, particularly given the ongoing support of his family. The court was also informed that Mason had been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), borderline personality disorder, and depression.
Impact on the Vulnerable Victims
Statements presented to the County Court outlined the severe psychological trauma experienced by both victims. The first woman described suffering from persistent feelings of mistrust and abandonment, stating: "I cannot trust people with my body and I’m afraid of people connected to a system like Adam." This statement highlights how abuse by a registered professional can completely destroy a participant's confidence in the broader disability support framework.
The second victim reported that the assault had resurfaced past trauma, leaving her highly fearful and distrustful of male support workers. Judge Karapanagiotidis noted that while there were no allegations of force or threats used in Mason's crimes, the legislative provisions under which he was sentenced were specifically designed to protect individuals with cognitive impairments from sexual exploitation by care workers who hold significant structural power over them.
Regulatory Bans and Watchdog Oversight
The case also highlights the role of the NDIS Quality and Safeguards Commission in monitoring worker conduct. In December 2023, during the intermediate period between Mason's suspension and his criminal sentencing, the NDIS Commission issued a banning order, legally prohibiting Mason from working as a care worker. This administrative step is a critical component of the NDIS safeguarding system, ensuring that workers under investigation for serious misconduct are removed from the sector before criminal proceedings conclude.
