Child sexual abuse is common in Australia. The best evidence of this comes from the 2023 Australian Child Maltreatment Study (ACMS), which surveyed 8,500 Australians aged 16 and over. The ACMS found 28.5% of the national population has experienced sexual abuse before age 18 by any person (adult or adolescent). Women were twice as likely as men to have experienced sexual abuse (37.3%-18.8%). Among 16-to-24-year-olds, prevalence was slightly lower (25.7%), but again with a massive gender disparity (35.2%-14.5%).
