The aim of this study was to explore the role of Mothers of young adults on the autism spectrum in Australia, during the transition to adulthood. Data collected through interviews were analysed using Interpretative Phenomenological Analysis resulting in two themes relevant to autism and inclusive practices: Inclusion Support and Mothers' Support. The findings showed that organisational pressure in meeting key educational performance outcomes influenced inclusive practices specifically for young adults on the autism spectrum who were deemed to require high levels of support. The inclusion support theme highlighted that schools, universities, and employers viewed Autism Spectrum Disorder through a deficit lens, with young adults on the autism spectrum positioned as low achievers. Whilst there are policies supporting inclusive education in Australia, individuals on the autism spectrum continue to experience inequity and exclusion, which were challenged by Mothers' persistence and reflected in the second theme on Mothers Support. The findings highlight the need for educational and socially inclusive interventions to support the heterogeneity in individual, social, communication, and behavioural challenges in young adults on the autism spectrum.
