Post on Prime Minister Albanese's contact form:

Please find attached a letter describing concerns from the Disability Representative Organisation (DRO) for autistic Australians, the national group that represents and advocates for the full autistic spectrum including many autistic Australians diagnosed formally with severe and/or profound disability many of whom cannot speak for themselves and whose interests are not represented by autistic self-advocates (who mainly represent their own part of the autism spectrum). 

Please note that government usually excludes this broader representative group from its (mostly dysfunctional) consultation and "co-design" processes. And NDIS ministers have avoided meeting with this representative group since the NDIS started. 

The issues are broader than the responsibility of the Health department - these are whole of government issues many of which government chooses to ignore.
