NDIS restrictive practices and behaviour support

Restrictive practices limit a person's rights or freedom of movement, so the NDIS regulates them tightly. They must be a last resort, authorised, and used only under a behaviour support plan. Here is what counts, the rules, and what you must report.

The regulated restrictive practices

Five types of restrictive practice are regulated under the NDIS: seclusion, chemical restraint, mechanical restraint, physical restraint and environmental restraint. Any use that limits a participant's rights or freedom of movement falls within these rules.

When they can be used

A regulated restrictive practice must be a last resort, the least restrictive option, used for the shortest time, and only to prevent harm. It must be authorised in line with your state or territory rules and set out in a behaviour support plan developed by an NDIS registered behaviour support practitioner.

Positive behaviour support

The goal is to reduce and eliminate restrictive practices over time through positive behaviour support: understanding why a behaviour happens and changing the environment and supports so it is no longer needed.

Reporting obligations

The use of a restrictive practice that is not authorised, or not in line with a behaviour support plan, is a reportable incident to the Commission. Providers who use regulated restrictive practices also have monthly reporting obligations.

📘 The Registration Policy Pack includes a restrictive practices and behaviour support policy mapped to the Practice Standards. Use code NDIS33 for 33% off.
