Autistic girls, women and gender diverse people have specific needs that are underrepresented in research. Research priorities are often established by funding bodies, researchers, parents, carers and health professionals and may not meet the needs of the diverse Autistic community. This co-produced project aimed to identify what research would benefit the lives of Autistic girls, women and gender diverse people in Australia. We interviewed 47 Autistic girls, women and gender diverse people aged seven and above and obtained feedback from an additional 411 Autistic people through an online survey. Autistic young people identified six key research priorities including (1) better understanding and support at school, (2) understanding our experiences, strengths and challenges, (3) autism specific mental health support, (4) Autistic friendships and relationships, (5) experiences of gender diversity and (6) accommodations to make life easier for us. Eight key research priority areas were identified by Autistic adults including (1) understanding and supporting specific needs in adulthood, (2) experiences of trauma, abuse and sexual violence, (3) supporting mental health and wellbeing, (4) addressing barriers in healthcare, (5) understanding and supporting physical health needs, (6) addressing barriers in education and the workplace, (7) understanding the role of society, embracing neurodiversity and the importance of Autistic identity and (8) co-designing research and supports with Autistic people. We provide a discussion around the importance of focusing on these research priority areas in future autism research in Australia.
