"Independent assessments are not independent," he told a parliamentary inquiry on Friday. "Robo-planning will blow up the NDIS. And it will also blow up the vision for this scheme to be there for all Australians." Professor Bonyhady said the change would tear up the social contract at the heart of the NDIS, which is that individualised support is available for all Australians who have a disability. He warned of anxiety and anger among people with disability. Trust between the community and the National Disability Insurance Agency, which runs the NDIS, has reached new lows. "Which is extraordinary given that the NDIA exists for one purpose and one purpose only - to serve people with disability, their families and carers," Prof Bonyhady said.
