The full answer
The NDIS Quality and Safeguards Commission is an independent federal body separate from the NDIA. While the NDIA handles the money side (plans, payments, participant pathway), the Commission handles registration and quality. Functions: provider registration and audit oversight, worker screening, Code of Conduct enforcement, complaint and reportable incident management, investigation and enforcement (compliance notices, banning orders, registration cancellation). From 2027, mandatory registration will significantly expand the Commission's regulated provider base.
