Disability support agencies and culturally and linguistically different (CALD) participants have pointed out language, culture, and an overly complex system as key barriers to access NDIS.

Dilky Wijeyekoon, senior program manager at the Australian Migrant Resource Centre (AMRC), believes many people are "missing" from the scheme and having more culturally competent support workers can improve the conditions.

Kendall Field, from the Disability Advocacy and Complaints Service of South Australia (DACSSA), has described the NDIS as "far too complex, legalistic and inflexible."
