The WA Register for Autism Spectrum Disorders is the first register of its kind in Australia. The Register has been documenting all newly diagnosed cases of Autism Spectrum Disorders in WA since January 1999.

The WA Autism Register collects information to describe the pattern of autism diagnosis in Western Australia, including:
- The number and ages of people diagnosed
- The severity of disability
- Shared biological, psychiatric and developmental features
- Group changes over time
Some of the applications of the WA Autism Register include:

The Western Australian Register for Autism Spectrum Disorders acknowledges the ongoing support of the Telethon Institute for Child Health Research and the ARC Centre of Excellence in Cognition and its Disorders.
