NDIS explained

What are the 5 regulated restrictive practices?

Updated 19 October 2026 · Checked against official NDIS and government sources

In plain English

The five regulated restrictive practices under the NDIS are seclusion, chemical restraint, mechanical restraint, physical restraint and environmental restraint. Each restricts the rights or freedom of movement of a person with disability. They may only be used as a last resort to reduce a risk of harm, as the least restrictive option for the shortest time, with state or territory authorisation where required, and set out in a behaviour support plan.

The five types

The NDIS (Restrictive Practices and Behaviour Support) Rules 2018 set out five kinds of regulated restrictive practice:

  • Seclusion: keeping a person alone in a room or physical space, at any time of day or night, where they are prevented from leaving, not helped to leave, or led to believe they are not allowed to leave
  • Chemical restraint: using medication or a chemical substance mainly to influence a person's behaviour. It does not include medication prescribed by a doctor to treat a diagnosed mental disorder, physical illness or physical condition
  • Mechanical restraint: using a device to prevent, restrict or subdue a person's movement mainly to influence their behaviour. It does not include devices used for therapeutic or non behavioural purposes, such as a prescribed postural support
  • Physical restraint: using physical force to prevent, restrict or subdue movement of a person's body, or part of it, mainly to influence their behaviour. A reflexive hands on move to guide someone away from harm is not physical restraint
  • Environmental restraint: restricting a person's free access to parts of their environment, including items or activities, for example locking the fridge, removing a phone, or stopping someone going into the community

The rules for using them

Regulated restrictive practices are not a normal part of support. Under the NDIS they must:

  • Be used only as a last resort, in response to a risk of harm to the person or others
  • Be the least restrictive option available and proportionate to the risk
  • Be used for the shortest possible time
  • Be authorised, where the state or territory requires authorisation
  • Be clearly set out in a behaviour support plan written by an NDIS behaviour support practitioner, alongside positive strategies that build independence and quality of life

Practices that should never be used

Some practices carry such a high risk of harm that they should never appear in a behaviour support plan. For physical restraint, the NDIS Commission says supine, prone, pin down, takedown techniques and basket holds must never be used, and no restraint may restrict breathing or digestion, inflict pain, hyperextend joints or put pressure on the chest or joints.

Removing someone's communication device may itself be abuse, and seclusion that denies a person's basic needs may be abuse or neglect.

Who can use them

Only registered NDIS providers can use regulated restrictive practices. Unregistered providers must not. The provider implementing the plan must report each month on any authorised use through the NDIS Commission portal.

Any use that is not authorised, or does not follow the behaviour support plan, is an unauthorised restrictive practice and must be reported to the Commission as a reportable incident. If it causes harm, that report is due within 24 hours.

Your rights as a participant or family

You have the right to be involved in developing any behaviour support plan, to understand why a practice is proposed and what is being done to reduce and stop it, and to have the plan reviewed. Ask your behaviour support practitioner how the plan will reduce restrictive practices over time.

If you think a restrictive practice is being used without authorisation, or by an unregistered provider, you can tell the NDIS Commission. If someone is in immediate danger, call 000.

For children and young people

For children, a restriction is not a regulated restrictive practice if it is age appropriate, in line with community standards and the same child safety step any parent would take whether or not the child has a disability, such as a child safety gate for a toddler. The Commission has a separate practice guide on restrictive practices with children and young people.

Common questions

What are the 5 types of regulated restrictive practices?

Seclusion, chemical restraint, mechanical restraint, physical restraint and environmental restraint.

Can an unregistered provider use restrictive practices?

No. You must be a registered NDIS provider to use regulated restrictive practices. Use by an unregistered provider should be reported to the NDIS Commission.

Is locking a fridge a restrictive practice?

Yes, restricting free access to food or drink, for example by locking a fridge or cupboard, is an environmental restraint and must be authorised and in a behaviour support plan.

Is prescribed medication a chemical restraint?

Not when it is prescribed by a doctor to treat a diagnosed mental disorder, physical illness or physical condition. It is chemical restraint when the primary purpose is to influence behaviour.

What happens if a restrictive practice is used without authorisation?

It is an unauthorised restrictive practice and a reportable incident. The registered provider must report it to the NDIS Commission, within 24 hours if it caused harm and otherwise within 5 business days.
