2023 AUSTRALIAN CHILD MALTREATMENT STUDY
What is Child Sexual Abuse
According to the 2023 Australian Child Maltreatment Study, Child sexual abuse includes any sexual act inflicted on a child by an adult or other adolescent, including contact and non-contact acts, for the purpose of sexual gratification, where true consent by the child is not present.
Prevalence
1 of 4 people experienced sexual abuse before the age of 18.



- 28.5% of the national population has experienced sexual abuse before age 18 by any person (adult or adolescent).
- Girls are almost twice as likely to experience child sexual abuse with 1 in 3 girls (37.3%) having experienced child sexual abuse compared to 1 in 5 boys (18.8%)
- 1 in 12 participants (8.7%) reported experiencing forced sex (rape) in childhood.
- 78% of those who experienced childhood sexual abuse reported it happening more than once.
Number of Abuse Incidents Reported by Child Sexual Abuse Victims
Perpetrators
- 18.5% of all Australians aged 16 and over had experienced child sexual abuse by an adult.
- 18.2% of Australians aged 16-24 (nearly 1 in 5) experienced sexual abuse by an adolescent before age 18.
- The majority of child sexual abuse is inflicted against girls by male adolescents the victim knew, and who were not their current or former romantic partner.
Trends
- Child sexual abuse by adults has declined. This is likely the result of increased awareness and parental supervision, school-based prevention programs, and laws and policies regulating institutions.
- Child sexual abuse by adolescents aged under 18 has increased in recent years.
Insights
- Much child sexual abuse by teens is influenced by lack of empathy, a desire for immediate sexual gratification, and male sexual entitlement. It is important to recognise that the data indicates most adolescent males do not inflict sexual violence.
- Parents are integral in reducing child sexual abuse. Educating children about their bodies, healthy relationships, consent, sex, empathy and gender equality instils key prosocial attributes required to reduce sexual violence.
- Emerging scientific consensus indicates age-appropriate sexuality education from early childhood through secondary school builds social and emotional skills that minimise the likelihood of perpetration.
