Australian research finds 68% of secondary students experienced cyberbullying in past year, platforms fail to detect most incidents

New research published in the Australian Journal of Education on 8 October 2026 found that 68 per cent of Australian secondary students surveyed reported experiencing cyberbullying in the past 12 months, with 82 per cent of incidents occurring in direct messages or private group chats on Instagram, Snapchat, Discord and TikTok. The study, conducted by researchers at the University of Melbourne and Monash University, surveyed 4,320 students aged 12 to 17 across five states between March and August 2026. Critically, the research found that platform-based reporting tools detected and removed only 11 per cent of abusive content reported by victims, and that 74 per cent of students who experienced serious cyberbullying did not tell a parent or teacher until weeks or months after the harm began.

The findings underscore two operational failures: platforms cannot detect abuse that unfolds in private channels using current content-moderation systems, and children delay disclosure until harm has escalated. Guardii addresses both gaps. The platform's anti-cyberbullying detection operates inside the direct-message and group-chat environments where the Melbourne and Monash researchers found the overwhelming majority of abuse occurs, identifying patterns of sustained targeting, coercion and escalation in real time without relying on a child to report or a platform to moderate after the fact. By surfacing a child in crisis to a parent or school safeguarding officer immediately, the system enables intervention at the point of harm rather than weeks or months later, closing the disclosure delay that the research identifies as a critical window of vulnerability.
