An inquest in Southport, Australia, has heard troubling details surrounding the care provided to 16-year-old Quinn Cook before his death by suicide in January 2023. The ongoing investigation is examining whether failures by caregivers, support providers, or government agencies contributed to the tragic death of the Gold Coast teenager, whose complex medical and mental health needs required intensive support.
Quinn Cook, from Logan, Queensland, was under the care of support workers employed by My Gold Coast Care Group (MGCCG), a provider operating under Australia’s National Disability Insurance Scheme (NDIS). During hearings this week, the court was told that the organization delayed reporting multiple suicide threats made by Quinn in the years leading up to his death.
The inquest heard evidence that Quinn had a complicated medical history, including autism spectrum disorder, ADHD, type 1 diabetes, emotional dysregulation, and repeated suicidal ideation. Coroner’s court proceedings revealed he had been hospitalized multiple times during his teenage years because of mental health crises and behavioral challenges.
Approximately two years before his death, Quinn moved into a Surfers Paradise apartment after difficulties at home reportedly made it impossible for him to continue living with his mother in Logan. The apartment was rented personally by MGCCG chief executive Marcia De Menezes, who had a prior connection to the family.
Although the accommodation was not officially funded or classified as specialized NDIS housing, support workers were reportedly assigned to remain with Quinn around the clock. Despite this arrangement, the court heard Quinn repeatedly threatened self-harm while under care.
During testimony, Marcia De Menezes admitted the company failed to immediately report several suicide threats to the National Disability Insurance Agency (NDIA) and the Queensland Department of Child Safety. While she rejected claims that the organization ignored Quinn’s risks, she acknowledged more could have been done.
“We were not aware how important it was to actually send those incident reports to NDIS,” De Menezes told the court. “I thought we were doing the best we could.”
The court also heard that staff members became overwhelmed by Quinn’s complex care needs. De Menezes described the teen’s threats of self-harm as “constant,” explaining that support workers struggled to manage the emotional and behavioral demands of his condition.
Lawyers representing the NDIA questioned whether Quinn’s suicide threats were taken seriously enough. De Menezes defended her organization’s efforts but admitted the situation was challenging and that improvements to reporting procedures had since been introduced.
Further testimony revealed that Quinn’s NDIS funding was rapidly exhausted after he moved into the apartment, with nearly $100,000 spent on support services within just three months. The provider denied accusations of intentionally overspending to secure additional funding, insisting the level of care required was extremely expensive and financially difficult to maintain.
Support workers who testified earlier in the inquest reportedly expressed concerns about limited training, Quinn’s isolation, and the lack of meaningful activities or social interaction available to him during his care.
The NDIS Quality and Safeguards Commission has since warned MGCCG that its registration could potentially be revoked, though the company is reportedly challenging that action.
As the inquest continues, Quinn Cook’s death has reignited broader discussions across Australia about mental health care, disability support services, youth suicide prevention, and accountability within the NDIS system. Loved ones continue mourning the loss of a teenager whose struggles highlighted the challenges faced by vulnerable young people requiring specialized care and protection.
