Sibling-to-Sibling Violence in Australia: Summary Report

Abstract

This report explores sibling-to-sibling violence (SSV) as one of the most common yet understudied forms of domestic and family violence. Unlike sibling rivalry, which is typically viewed as a normal part of development, SSV is characterised by repetitive, intentional, and harmful behaviours. Drawing on data from a national survey of young Australians aged 16-20, the report reveals the prevalence, nature, and impact of SSV, distinguishing it from general sibling conflict. Findings indicate that approximately 303 young people reported experiencing SSV, with a high overlap between being both victims and perpetrators. <br><br>

The report identifies various forms of SSV, including verbal, physical, and psychological abuse, as well as severe behaviours like threats, non-fatal strangulation, and sexual abuse. Many young people reported co-occurring forms of violence, suggesting that SSV often manifests as a pattern rather than isolated incidents. Significant gender differences were observed, with cis male participants more likely to report using SSV and cis female or trans/non-binary participants more likely to report being victims. SSV frequently co-occurs with other family violence, particularly child-to-parent abuse, and is commonly linked to adverse childhood experiences. The impacts of SSV on young people are extensive, affecting their physical, psychological, and social wellbeing, educational achievements, and, for some, cultural wellbeing.<br><br>

The report emphasises the need for greater awareness of SSV and the development of evidence-based policies and interventions that address SSV within broader family dynamics. Recognising the significant harms associated with SSV, it calls for further research and supportive programs to address these behaviours effectively.
