How far back do NDIS auditors look at incident and complaints records?

Auditors typically review records covering the period since your last audit or, for initial audits, from the date of your registration. There is no fixed minimum, but expect at least 12 months of incident and complaints records to be examined. Gaps in that period are a common finding.

Do NDIS auditors interview participants directly?

Yes. Approved quality auditors are trained to conduct interviews with participants, families, and carers, and to observe service delivery where practicable. The 2026 strengthened framework places greater weight on participant experience as an evidence source, not just written records.

What happens if auditors find missing documents at a SIL audit?

A missing or non-conforming document results in a finding graded as either a minor or major non-conformance. Minor findings require a corrective action plan. Major findings can delay registration approval or trigger conditions on your registration. Repeated or serious findings may be referred to the NDIS Commission for regulatory action.

Is a behaviour support plan required for every SIL participant?

A behaviour support plan is required for every participant for whom a regulated restrictive practice is being used. If no restrictive practices are in use, a BSP is not automatically mandatory — however, a risk assessment and any relevant de-escalation strategies should still be documented in the individual support plan.

How often must individual support plans be reviewed for SIL participants?

The NDIS Practice Standards require support plans to be reviewed at regular intervals and whenever there is a significant change in the participant's needs or circumstances. In practice, SIL providers typically conduct formal reviews at least annually, with more frequent check-ins documented in progress notes.

Do all staff need an NDIS Worker Screening clearance before an audit?

All workers in risk-assessed roles — which includes most direct support workers in SIL — must hold a current NDIS Worker Screening clearance. Auditors verify clearance currency and will flag any worker who delivered supports without one as a non-conformance, even if the worker has since obtained the clearance.

What Documents Do NDIS Auditors Actually Check?

What NDIS Auditors Are Actually Looking For

When an approved quality auditor arrives — whether for an initial registration audit or a renewal — they are not simply verifying that you have a policies folder on a shelf. They are testing whether your documented systems reflect what actually happens in practice, and whether every participant receives support that meets the NDIS Practice Standards. For SIL providers, the scrutiny is especially intense because the 2026 mandatory registration pathway has brought a larger cohort of providers into audit scope for the first time.

The list below covers the document categories auditors consistently examine. It is organised to match the structure of the NDIS Practice Standards so you can map your own document set against it before your audit date.

Core Module Documents

All registered NDIS providers — regardless of the supports they deliver — must demonstrate compliance with the Core Module. Auditors look for evidence in the following areas:

1. Rights and Responsibilities

A current participant rights and responsibilities policy, signed off at board or executive level
Evidence that participants have received and understood information about their rights (service agreements, welcome packs, accessible-format versions for people with communication needs)
Copies of current service agreements for each active participant

2. Governance and Operational Management

Organisational charts showing the chain of accountability
Board or management meeting minutes demonstrating oversight of quality and safety matters
A documented quality management framework or continuous improvement plan with evidence of actions completed
Insurance certificates (public liability, professional indemnity) current at the audit date

3. Feedback, Complaints and Incidents

This is one of the highest-risk areas for non-conformance. Auditors will ask to see:

Your complaints management policy and procedure
The live complaints register — including closed complaints — with resolution timeframes recorded
Your incident management policy, covering classification of incidents by severity
The incident register, with evidence that reportable incidents were notified to the NDIS Commission within the required timeframes
Post-incident review records demonstrating that systemic lessons were identified and acted upon

4. Human Resources and Staff Management

NDIS Worker Screening clearance records for all workers in risk-assessed roles — this is non-negotiable
Police check and reference check records for workers not yet in the screening pathway
Induction records showing that every worker completed mandatory orientation before delivering supports
Ongoing training records, particularly for NDIS Code of Conduct, abuse and neglect recognition, and manual handling
Evidence that the NDIS Worker Orientation Module was completed by all relevant workers
Performance review records and any disciplinary or conduct action files

SIL-Specific and High-Intensity Support Documents

SIL providers carry additional documentation obligations under the High Intensity Daily Personal Activities and the Specialist Behaviour Support registration groups. Auditors will drill into:

Individualised Support Plans

A current, person-centred support plan for every participant — not a templated generic document
Evidence the plan was co-produced with the participant and, where appropriate, their support network
Dated review records confirming the plan is reviewed at least annually or when the participant's needs change significantly
Goal-tracking records showing progress against participant goals

Risk Assessments

Individual risk assessments addressing physical, environmental, health, and psychosocial risks
Emergency and evacuation plans specific to each residence, with evidence of regular practice drills
Health management plans where a participant has a complex health condition (epilepsy, dysphagia, PEG feeding, diabetes, etc.)

Restrictive Practices

For any provider using regulated restrictive practices, this document set is the most frequently cited area of non-conformance at audit:

A current behaviour support plan prepared or reviewed by an NDIS-registered behaviour support practitioner
State or territory authorisation documents for each regulated restrictive practice in use
A restrictive practices register recording every instance of use, including duration and the worker involved
Evidence the participant, their guardian, or nominee has been consulted about the practice and its reduction plan
Reportable-conduct notifications to the NDIS Commission where applicable

The 2026 Strengthened Practice Standards — What Has Changed

The strengthened NDIS Practice Standards, which underpin the 2026 mandatory registration framework, place greater emphasis on participant outcomes and provider culture rather than paperwork compliance alone. In practical terms, auditors are increasingly expected to:

Interview participants and their families, not just staff
Observe actual service delivery where possible
Triangulate what documents say against what workers describe in interviews
Look for evidence of genuine continuous improvement, not just completed forms

This means a perfectly formatted policy folder will not save you if participant interviews reveal that staff are unaware of its contents, or that a complaints process exists on paper but participants do not know how to use it.

Common Non-Conformance Findings

Document Area	Typical Finding	How to Fix It Before Audit
Incident register	Incidents recorded but NDIS Commission notification timeframes not met or not documented	Add a notification-date column; cross-check against Commission portal submission records
Worker screening	Clearances recorded on intake but not tracked for expiry	Build a renewal-date alert into your HR system or a simple spreadsheet with 60-day reminders
Behaviour support plans	Plan present but not reviewed within the required period, or authorisation documents missing	Audit every BSP for review date and match each restricted practice to a current state-authority document
Support plans	Generic template with minimal participant-specific content	Replace with individualised plans co-signed by participants; retain the draft and review history
Training records	Completion certificates held for some staff but not all; no evidence of content relevance	Maintain a central training matrix showing each worker's completions, dates, and certificate file references

A Practical Document Checklist for SIL Providers

Before your audit, work through the following list and mark each item as ready, in-progress, or missing:

Policies covering rights, complaints, incidents, restrictive practices, safeguarding, and HR
Service agreements for all current participants
Complaints register with resolution records
Incident register with Commission notification evidence
NDIS Worker Screening clearance records — current and tracked for expiry
Induction and ongoing training matrix with completion certificates
Individualised support plans, dated and co-signed
Individual risk assessments and emergency evacuation plans
Health management plans for participants with complex health needs
Behaviour support plans with current state-authorisation documents
Restrictive practices register with instance-level records
Quality management plan with evidence of completed improvement actions
Insurance certificates valid at audit date
Board or management oversight records (minutes, sign-offs)

Getting Audit-Ready

The most effective preparation is a structured internal audit — working through every document category above, identifying gaps, and assigning an owner and due date to each remediation action. Providers approaching mandatory registration for the first time in 2026 often find that their biggest gap is not a missing policy but the absence of evidence that the policy is actually being followed — completed forms, signed checklists, dated records of conversations with participants.

If you are building your document library from scratch or want a pre-verified template set, ndiscompliant.com.au offers a 74-document audit-ready SIL compliance kit that covers every item in the Core Module and the SIL-specific registration groups, formatted to meet current NDIS Commission expectations.

Whatever path you take, start the document review at least three months before your audit date. Non-conformances that are identified and corrected before an audit are always preferable to findings that require post-audit remediation under the Commission's corrective action process.
