Inquest Into The Death Of Catherine Maree Broadbent

39y · Female·multiple drug toxicity (etizolam and carisoprodol as major components)

Catherine Broadbent, 39, died from multiple drug toxicity involving benzodiazepines (etizolam, carisoprodol) sourced from the dark web, in the context of chronic borderline personality disorder and complex PTSD with lifelong suicidality. She was managed by an intensive community mental health team following a Multi-Agency Response Guide (MARG) designed to minimise hospitalisations after previous admissions had proven counterproductive and traumatising. The coroner found the clinical care reasonable and appropriate within available structures. However, the case highlights a critical service gap: Cathy required intermediate residential respite and therapeutic recovery services—neither acute hospital admission nor community outreach alone—which were unavailable. Short voucher-funded respite stays (72 hours twice monthly) at Hyson Green proved insufficient. The coroner noted that Victoria's Royal Commission and national mental health policy frameworks identify crisis respite services as essential but missing from many Australian systems, yet deferred making public safety findings due to passage of time since 2018.
