Restrictive Practices and the NDIS: Authorisation, Reporting, and Reduction

When "keeping someone safe" and "restricting their freedom" are the same action

Most SIL providers never set out to use a restrictive practice. It usually starts with a real safety concern — a participant who tries to leave the house at night, a behaviour of concern that puts someone at risk of harm — and a support worker who reaches for whatever keeps everyone safe in the moment. The trouble is that a locked door, a sedating medication given "just to calm things down," or holding someone's arms to stop them lashing out can each meet the legal definition of a regulated restrictive practice, whether or not anyone in the house thought of it that way. Once that line is crossed, a specific set of authorisation, planning, and reporting obligations switches on — and getting them wrong is one of the more serious compliance and safeguarding failures a provider can have. This guide sets out what counts, what a behaviour support plan needs to contain, what you must report each month, and why reduction — not management — is the actual goal.

What counts as a regulated restrictive practice

The NDIS Quality and Safeguards Commission regulates five categories of restrictive practice. A restraint or restriction only falls into scope if its primary purpose is to influence or manage a participant's behaviour, not to deliver clinical treatment or everyday support:

• Seclusion — confining a person alone in a room or physical space, at any time of the day or night, from which they cannot freely exit.
• Chemical restraint — a medication or chemical substance used primarily to influence a person's behaviour, as distinct from medication prescribed for a diagnosed condition or for therapeutic purposes.
• Mechanical restraint — using a device or piece of equipment to restrict a person's movement, where the device is not solely for a therapeutic or non-behavioural purpose (for example, a seatbelt used only for safe transport is not in scope; a device fitted specifically to stop someone hitting themselves is).
• Physical restraint — the use of, or assistance from, another person's body to prevent, restrict, or subdue a participant's movement.
• Environmental restraint — restricting a person's free access to all or part of their environment, including their home — locked doors, gates, or removed access to particular rooms or items are common examples.

These categories, and the "primary purpose" test that separates a restrictive practice from ordinary clinical or safety measures, are set out in the NDIS Commission's guidance on regulated restrictive practices. The practical implication for a SIL house is that intent and effect both matter: a door locked so a participant can sleep undisturbed reads very differently to a door locked specifically to stop them leaving because of a behaviour of concern — and only the second is a restrictive practice, even though the physical action is identical.

Authorisation is a state or territory matter, not a Commission approval

A common misconception is that the NDIS Commission "signs off" on restrictive practices. It doesn't. Authorisation and consent for using a regulated restrictive practice with a specific participant are governed by the law of the state or territory where that participant lives — each jurisdiction runs its own authorisation body, process, and consent requirements. The Commission's role is to regulate behaviour support nationally: setting the rules for how practices are planned, implemented, and reported, and holding providers to account for compliance. As the Commission's guidance makes clear, a regulated restrictive practice may only be used as a last resort, and only where it is authorised in line with the relevant state or territory framework and included in a current behaviour support plan.

The consequence that catches providers out is what happens when a practice is used without that authorisation and plan in place — a support worker restraining a participant in an unplanned crisis, say, or a house continuing to lock a door after a plan has lapsed. That is an unauthorised use of a restrictive practice and a reportable incident in its own right, separate from the monthly reporting obligation covered below.

Behaviour support plans: interim, comprehensive, and who can write them

A behaviour support plan is the document that connects a participant's needs to any restrictive practice in use, and it has to be developed by a suitably qualified NDIS behaviour support practitioner — not by house staff or management, however experienced. The Commission's rules for behaviour support and restrictive practices set two stages:

• An interim behaviour support plan — a short, safety-focused plan put in place quickly, while a full functional behaviour assessment is still underway, so that any restrictive practice already in use has an authorised basis rather than operating in a gap.
• A comprehensive behaviour support plan — developed following a functional behaviour assessment, setting out the formulation of the behaviour, proactive and skill-building strategies, and — critically — the specific steps and timeframe for reducing and, where possible, eliminating any restrictive practice the plan includes.

A comprehensive plan cannot be lodged with the Commission without the functional behaviour assessment behind it — one reason interim plans exist, to cover the safety gap honestly rather than skipping the assessment step. For providers who implement a plan containing a regulated restrictive practice — as most SIL providers do — the NDIS Practice Standards apply an additional supplementary module on implementing behaviour support plans, setting specific expectations for how your organisation trains staff, follows the plan as written, and escalates when it isn't working.

The monthly reporting obligation providers consistently underestimate

If your organisation implements a behaviour support plan that includes a regulated restrictive practice, you are an "implementing provider" for reporting purposes, and you carry a recurring obligation that doesn't stop once the plan and authorisation are sorted. Under the Commission's rules for implementing providers, you must submit a monthly report, via the NDIS Commission Portal, covering every regulated restrictive practice named in the participant's plan — including months where the practice was not actually used. A "nil" month is still a reportable month; silence is not an acceptable substitute for a report.

The Commission's own Quick Reference Guide for monthly reporting walks through the portal steps, and reports fall due on a short, fixed turnaround after the end of each reporting month — not a task that fits neatly at the end of a busy month; it needs a standing process, not a memory. Providers running several participants on active plans, across different practices and review dates, are the ones most likely to lose track of a report quietly, and a missed report is a gap the Commission can identify well before your next audit does.

Reduction and elimination: the actual point, not a box to tick

It's easy to read all of the above as a reporting and paperwork exercise. It isn't. Every comprehensive behaviour support plan that includes a regulated restrictive practice has to set out how that practice will be reduced, and where possible eliminated, over time — not simply managed indefinitely. This sits within the Commission's positive behaviour support framework, which is explicitly values- and rights-based: the goal is to understand why a behaviour is occurring and meet the person's underlying need, so the restriction becomes less necessary — not to find a more sustainable way to keep applying it.

That reduction expectation is grounded in the Commission's Positive Behaviour Support Capability Framework and the national commitment to reducing and eliminating restrictive practice use across the disability sector. A plan review that simply renews the same restrictive practice year after year, with no documented change in strategy or trend, is exactly the pattern the Commission is watching for — and the pattern that should trouble you too, on the participant's behalf. Genuine reduction protects a person's dignity and autonomy; it's also the clearest evidence that your organisation takes positive behaviour support seriously rather than using it as a label.

Where providers commonly get this wrong

• Treating "restrictive" as obvious. Environmental and chemical restraint are the categories most often missed — a locked linen cupboard, or a PRN medication given specifically to settle escalating behaviour, can both be in scope even when nobody intended them as a "restraint."
• Letting an interim plan quietly become permanent. Interim plans exist to cover a gap while an assessment is completed, not as a durable substitute for the comprehensive plan and its reduction strategy.
• Missing nil months. Teams remember to report a month with an incident; the nil months are where reporting habits lapse first.
• No visible reduction trend. A plan reviewed repeatedly with the same restrictive practice, at the same frequency, and no documented attempt to reduce it, is a governance gap even if every report was filed on time.
• Frontline staff untrained on the specific plan. A plan is only as good as the person implementing it at 2am — staff need to know the participant's actual strategies, not restrictive practice concepts in the abstract.

How Compliance Care helps

We help providers build genuine, working competence against the NDIS Practice Standards' behaviour support requirements — the systems that keep authorisation current, plans reviewed on schedule, monthly reports filed (including the nil months), and reduction genuinely tracked rather than assumed. That's a governance and workforce problem as much as a paperwork one, which is why it sits alongside our compliance training, built to make sure the staff actually implementing a behaviour support plan understand it in practice, not just in policy.

If restrictive practices are one part of a broader audit-readiness gap, our SIL audit checklist is a practical starting point for seeing where else your evidence base needs work. It's worth reading alongside our guides on workforce capability as a compliance requirement and strengthening participant safeguarding, since behaviour support, workforce competency, and safeguarding all draw on the same underlying evidence.
