When does the 24-hour notification clock start for a missing NDIS participant?

The 24-hour clock starts when your organisation becomes aware that the participant cannot be located and their safety cannot be confirmed. It does not wait for police confirmation that the person is officially missing. If your staff cannot confirm the participant is safe after reasonable attempts, treat it as a reportable incident and begin the notification process immediately.

Do I need to notify the NDIS Commission if the participant is found within a few hours?

Yes, in most cases. If the participant was in a situation of serious risk to their safety during the period they were missing — due to their disability, health needs, or the circumstances of their disappearance — the incident remains reportable regardless of how quickly they were located. Document the full sequence of events and submit your report as required.

What if the five-day written report deadline arrives and the participant still has not been found?

You must still submit the written report by the five-day deadline. Include all information known at that time — the facts of the incident, steps taken, police involvement, and current status. Clearly state that the situation is ongoing. You can and should provide updates to the NDIS Commission as new information becomes available.

Who submits the reportable incident notification to the NDIS Commission?

The notification must be submitted by the registered NDIS provider through the myNDIS provider portal. Responsibility typically rests with the provider's Responsible Person or a designated compliance officer. The procedure for who within your organisation submits notifications should be documented in your incident management policy.

Can a missing-participant incident also trigger restrictive practice obligations?

It can, depending on the response. For example, if staff implement any form of physical restraint, environmental restriction, or other regulated restrictive practice during the search or upon the participant's return, those actions must be reported separately under the restrictive practices framework. Your behaviour support plan should guide any post-return de-escalation response.

What are the consequences of missing the 24-hour notification timeframe?

Late notification is a direct breach of the NDIS (Incident Management and Reportable Incidents) Rules 2018. The NDIS Commission can investigate, issue a compliance notice, require an action plan, or in serious cases take action against your provider registration. Late reporting also demonstrates to auditors that your incident management system is inadequate, which can affect your audit outcome under the strengthened Practice Standards.

Missing participant: NDIS notification timeframes

Why missing-participant incidents demand immediate action

For Supported Independent Living (SIL) providers and other registered NDIS providers, a participant going missing is one of the most time-critical incidents you will ever face. The stakes are high: a person with disability may be in immediate danger, and your legal obligations under the NDIS (Incident Management and Reportable Incidents) Rules 2018 begin counting down the moment your organisation becomes aware something is wrong.

Understanding the notification chain — who to tell, in what order, and within what timeframes — is not optional. The NDIS Commission has the power to investigate, issue compliance notices, and take action against registrations where providers have failed to meet their reporting duties. With the strengthened NDIS Practice Standards coming fully into effect across 2026, auditors are paying close attention to incident management systems and whether providers can demonstrate they acted swiftly and documented correctly.

Is a missing participant a reportable incident?

Yes. Under the NDIS (Incident Management and Reportable Incidents) Rules 2018, a reportable incident includes the death of an NDIS participant and any incident in which the participant is unexpectedly placed in a situation of serious risk to their safety or welfare. A participant who goes missing — particularly one who is unable to communicate, has limited capacity to seek help, or has health needs requiring regular support — almost always meets the threshold of serious risk.

Providers must not wait until a participant is confirmed missing for an extended period. If reasonable attempts to locate the person have failed and you cannot confirm their safety, the incident must be treated as reportable and the notification process must begin immediately.

The notification timeframes you must meet

The NDIS Commission's reportable incident framework sets out a two-stage reporting requirement:

Initial notification — within 24 hours: Providers must notify the NDIS Commission of a reportable incident within 24 hours of becoming aware of it. For a missing participant, this clock starts when your staff first identifies that the person cannot be located and their safety cannot be confirmed. The initial notification does not need to be a full written report — it must convey the nature of the incident, when it occurred (or when it was first identified), and the immediate steps taken. This is submitted through the myNDIS provider portal.
Written report — within five days: A full written report must be submitted to the NDIS Commission no later than five days after the provider became aware of the reportable incident. This report must document the facts of the incident, the response taken, any immediate harm-reduction steps, and what is being done to prevent recurrence. If the situation is still unresolved when the five-day period arrives, you must still submit the report based on what is known at that time and update it as the situation develops.

These timeframes are non-negotiable. Providers who submit late — even by a matter of hours — can face compliance findings during audits and reviews.

Notifying police: a parallel, urgent obligation

Notifying the NDIS Commission is not your only immediate obligation. You must also contact police without undue delay. In practice, for a participant who cannot be located and whose safety is uncertain, a police report should be made before or simultaneously with your internal escalation process — not after.

Do not wait to see whether the participant "turns up." For participants with complex support needs, cognitive disability, mental illness, or health conditions, every hour matters. Your incident management procedure should make police notification an explicit, early step — not a contingency.

Who else must be notified

Beyond the NDIS Commission and police, providers must consider the following:

The participant's emergency contacts and family/guardian: Where you hold consent and contact details, notify the person's emergency contacts as soon as it is practicable to do so. If a guardian or nominee holds decision-making authority, they must be informed promptly.
The participant's NDIS support coordinator or LAC: If the participant has a support coordinator, inform them so they can assist with coordination and keep the NDIA informed as appropriate.
Your organisation's senior leadership: Your internal incident escalation chain must be activated. SIL providers operating at scale must ensure site managers are not handling this alone — escalate to your Responsible Person and compliance lead.

What your written report to the NDIS Commission must include

The five-day written report is a formal document and auditors will scrutinise it. Your report must clearly address:

The date and time the participant was last seen and by whom
The date and time staff became aware the participant was missing
What steps were taken to locate the participant, and when
When police were contacted and the police report or event number
Who within the organisation was notified and when
Who externally (family, guardian, support coordinator) was notified and when
The current status of the participant at the time of writing
Any immediate safeguarding actions taken
An outline of your planned investigation and review process

If the incident remains unresolved (the participant has not been located) when you submit the report, state this clearly and commit to providing updates. The Commission may request supplementary information.

The investigation and post-incident review

After the immediate emergency is resolved, providers have an obligation to investigate the incident and identify contributing factors. The strengthened NDIS Practice Standards place increased emphasis on a genuine, participant-centred approach to incident review — not a box-ticking exercise.

Your review should examine:

Whether the participant's support plan adequately addressed known risks related to absconding or leaving without notice
Whether staffing levels and supervision at the time were appropriate
Whether the support environment (e.g. dwelling layout, security features) presented risk factors
Whether any behaviour support plan or risk protocol was followed correctly
What systemic changes are required to reduce the likelihood of recurrence

Findings from this review must be documented and, where they affect the participant's support plan, shared with the participant and their support network (with appropriate consent).

Common compliance failures in missing-participant incidents

Failure	Why it matters
Late initial notification (beyond 24 hours)	Direct breach of the Reportable Incidents Rules; frequently cited in Commission investigations
No police notification or delayed police notification	Puts the participant at risk and undermines the provider's duty of care
Incomplete written report (missing timestamps or response steps)	Fails the written-report standard; auditors will flag this as inadequate incident documentation
No post-incident review conducted or documented	Non-conformance under the strengthened Practice Standards' incident management requirements
Failure to update participant's support plan after the incident	Leaves the same risk factors in place; exposes the provider to repeat incidents and compliance action

Preparing your organisation before an incident occurs

The best time to build your missing-participant response capability is before an incident happens. Your incident management system should include a written procedure specifically for missing participants, with clear role assignments, a checklist of notification steps, and contact details for police, the NDIS Commission portal, and emergency contacts stored securely and accessibly by staff on shift.

Your staff must be trained on this procedure — not just briefed once during induction. Under the strengthened 2026 NDIS Practice Standards, auditors will ask to see evidence that staff understand their obligations and have practised the response process.
