As a group, Indigenous Australians experience higher rates of sexually transmitted infections, bloodborne viruses, and teen pregnancy than non-Indigenous Australians. This resource sheet examines evidence on the effectiveness of sexual health education programs for Indigenous Australians. It outlines what works, what doesn't, and what further research is needed. Information is provided on: the prevalence of notifiable sexually transmissible infections; types of sexual health education programs; facilitators and barriers; and increasing the evidence base.
