Support services have seen an increase in new and complex matters, but the opposite has been recorded by police.
The number of assaults reported to police by women was seven times higher than men, and almost 90 per cent of women who experienced assault by a man in the past decade did not report it.
Ms Yates said adopting recommendations made by the Sexual Assault Reform Program in 2005, including giving victims the ability to choose the gender of the police officer they report to, would make reporting easier.
She said the ACT was well-placed to adopt an international model of creating a “one-stop shop” for victims of violence to report the matter and access support services.
