NDIS Who Does What: The NDIA, LAC, Commission and Planner Explained
NDIS who does what, in plain English: what the NDIA, your LAC, planners, support coordinators and the NDIS Commission each do — and who to call.

Who do I contact if a support worker treats me badly?
Contact the NDIS Quality and Safeguards Commission on 1800 035 544 — they handle safety and quality complaints about providers and workers. This is a different body from the NDIA, which only handles your funding. If you or someone else is in immediate danger, call 000 first. You do not need to prove…
What can I do if I disagree with a decision about my plan?
First, ask the NDIA for an internal review of the decision. If you are still unhappy, you can apply to the Administrative Review Tribunal (ART), an independent body that reviews government decisions. An advocate — often free and independent — can help you understand the decision and prepare, and…
