Aboriginal and Torres Strait Islander people with autism spectrum disorder, used interchangeably with the term autism, are among the most marginalised people in Australian society. This review maps out existing and emerging themes in the research involving Indigenous Australians with autism based on a search of the peer-reviewed and grey literature. Our search identified 1457 potentially relevant publications. Of these, 19 publications met our inclusion criteria and focused on autism spectrum disorder diagnosis and prevalence, as well as carer and service provider perspectives on autism, and autism support services for Indigenous Australians. We were able to access 17 publications: 12 journal articles, 3 conference presentations, 1 resource booklet and 1 dissertation. Findings suggest similar prevalence rates for autism among Indigenous and non-Indigenous Australians, although some Aboriginal and Torres Strait Islander people with autism may not receive a diagnosis or may be misdiagnosed. Research on the perspectives of Aboriginal and Torres Strait Islander carers and Indigenous and non-Indigenous service providers is discussed in relation to Indigenous perspectives on autism, as well as barriers and strategies to improve access to diagnosis and support services. Although not the focus of our review, we briefly mention studies of Indigenous people with autism in countries other than Australia.
