SIL Certification Audit: What Auditors Look For and How Long It Takes
If you are an unregistered SIL provider facing mandatory registration from 1 July 2026, here is the direct answer: SIL registration typically takes 6 to 12 months from start to finish, and requires a certification audit assessing 22+ practice standards across multiple modules. This guide covers exactly what auditors look for, common failures, and a realistic timeline for first-time SIL providers.
How Long Does SIL Registration Take?
SIL registration typically takes 6 to 12 months from initial preparation to receiving your Certificate of Registration. The actual timeline depends on your starting point, the gaps in your current systems, and auditor availability.
Here is a realistic breakdown:
Total realistic timeline: 6 to 12 months
Providers who already have strong governance systems and documentation may complete the process faster. Providers starting from scratch, or those with significant gaps, should plan for the longer end of this range.
Why Does SIL Registration Take So Long?
SIL registration takes longer than other NDIS registrations because SIL is classified as a high-risk support requiring the most comprehensive audit pathway. Four factors drive the extended timeline.
Certification audit required. SIL providers must complete a certification audit, not a verification audit. Certification audits involve two stages (desktop review and on-site assessment), multiple site visits, staff interviews, and participant interviews. This is significantly more intensive than a single-stage verification audit.
Evidence of implementation required. Auditors do not just review your policies. They require evidence that your systems are implemented and operating. This means you need to generate records, conduct internal audits, document incidents and complaints, and show that staff are trained before your audit. You cannot rush this evidence gathering.
Complexity of SIL supports. SIL providers are often required to administer medication, deliver mealtime supports, provide high-intensity personal care, and implement behaviour support plans including restrictive practices. These additional supports increase the scope of the audit and the volume of evidence required.
Auditor availability is limited. As the transition to mandatory registration progresses, demand for NDIS auditors is increasing. Providers who wait to begin may face delays of weeks or months securing an audit slot.
What Is a SIL Certification Audit?
A SIL certification audit is a comprehensive two-stage assessment conducted by an NDIS-approved quality auditor to determine whether your organisation meets the NDIS Practice Standards required for SIL registration.
Stage 1: Desktop review
The auditor reviews your documentation remotely, including:
- Governance documents (business registration, structure, key personnel)
- Policies and procedures
- Risk management framework
- Quality management system
- Staff training records and screening evidence
- Internal audit reports
The auditor identifies any gaps that must be addressed before Stage 2.
Stage 2: On-site assessment
The auditor visits your SIL properties and conducts:
- Site inspections of SIL accommodation
- Staff interviews (frontline workers, supervisors, management)
- Participant interviews (with consent)
- Participant file reviews
- Observation of service delivery (where possible)
- Verification that documented systems match actual practice
The auditor assesses your compliance against all applicable Practice Standards modules.
Which Practice Standards Apply to SIL Providers?
SIL providers must demonstrate compliance with multiple NDIS Practice Standards modules. The specific modules depend on your service model, but most SIL providers are assessed against the following:
Core Module (all registered providers)

Module 1: High Intensity Daily Personal Activities
Most SIL providers deliver high-intensity supports and must comply with this module:
- Assessment and planning for high-intensity personal care
- Safe delivery of personal care respecting dignity
- Mealtime management and nutrition supports (where required)
- Responsive support that adapts to changing needs
- Incident escalation for high-intensity supports
- Worker competency for complex care tasks
Module 2a: Implementing Behaviour Support Plans
If your SIL services involve implementing behaviour support plans or using restrictive practices, you must also comply with this module:
- Understanding and correctly implementing Behaviour Support Plans
- Authorisation processes for restrictive practices
- Working to reduce and eliminate restrictive practices
- Person-centred, trauma-informed support
- Collaboration with Behaviour Support Practitioners
- Worker training for behaviour support implementation
- Monitoring and reporting on behaviour support outcomes and restrictive practices
Note on new SIL Practice Standards: The NDIS Commission is developing SIL-specific Practice Standards that had not been finalised as of April 2026. Providers should prepare against the current standards while monitoring the Commission website for updates, as audit requirements may be adjusted once the new standards are published.
What Do Auditors Look For in a SIL Certification Audit?
Auditors assess whether your documented systems match your actual practice. They look for evidence that you are implementing the Practice Standards — not just that you have written policies.
Here are the key areas auditors focus on for SIL providers.
Restrictive Practices
Restrictive practice compliance receives significant scrutiny in SIL audits. Auditors will verify:
- All restrictive practices are authorised under state/territory legislation
- Current Behaviour Support Plans exist for every participant where restrictive practices are used
- Plans are developed by NDIS-registered Behaviour Support Practitioners
- Restrictive practice use is reported to the NDIS Commission within required timeframes
- Documented strategies exist to reduce restrictive practice use
- All staff implementing restrictive practices are trained and assessed as competent
Common failure: Using restrictive practices without proper authorisation or without a current Behaviour Support Plan.
Incident Management
SIL services operate 24/7, which means incidents will occur. Auditors expect mature incident management systems:
- Complete incident register with investigation records
- Root cause analysis for all incidents
- Documented corrective actions
- Reportable incidents notified to the NDIS Commission within required timeframes (24 hours for most categories; 5 business days for unauthorised restrictive practices unless harm occurred)
- Evidence that incidents inform risk management and quality improvement
Common failure: Logging incidents without investigating them or documenting corrective actions.
Workforce Governance
SIL workforce often includes casual staff, agency workers, and overnight support workers. Auditors will examine:
- All workers have current NDIS Worker Screening clearances
- All workers have completed the NDIS Worker Orientation Module
- Role-specific training is completed for SIL tasks (personal care, medication, mealtime management, behaviour support)
- Competency is assessed for high-risk tasks
- Regular supervision is provided for all workers including casuals
- Supervision sessions are documented
- Workforce planning is in place to ensure continuity of supports
Common failure: Gaps in worker screening or supervision records for casual and agency staff.
Participant Rights and Choice
SIL involves shared living arrangements, creating tension between group dynamics and individual rights. Auditors will examine:
- Evidence participants were involved in their support planning
- Compatibility assessments for shared housing
- How participant privacy is maintained in shared environments
- How participants provide feedback or raise concerns
- How individual needs are balanced against shared arrangements
Common failure: No documented evidence of participant involvement in planning or decision-making.
Governance and Risk Management
Auditors assess whether your organisation has the governance structures to deliver safe, quality SIL services:
- Clear organisational structure with defined roles and responsibilities
- Financial viability to sustain operations
- Risk register identifying key risks with control measures
- Regular risk reviews documented
- Quality management system with internal audits
- Policies reviewed and updated regularly
Common failure: Policies exist but have not been reviewed since they were written.
What Documentation Do Auditors Review for SIL Registration?
Auditors review extensive documentation during a SIL certification audit. Here is a checklist of what you need to prepare:
Governance and Business Structure
- Certificate of incorporation or business registration
- Organisational structure chart
- Key personnel details and qualifications
- Evidence of financial viability
- Board or governance meeting minutes (if applicable)
Policies and Procedures
- All policies required under NDIS Practice Standards
- Evidence policies have been reviewed
- Version control showing policy history
- Procedures align to actual work practices
Risk and Quality Management
- Risk register with control measures
- Evidence of regular risk reviews
- Internal audit schedule and reports
- Quality improvement register
- Evidence of improvements implemented
Workforce
- Worker screening register with clearance dates and expiry
- Training register for all workers
- Supervision records
- Competency assessments for high-risk tasks
- Induction records
- Signed code of conduct acknowledgements
Incident and Complaints Management
- Incident register with investigation records
- Complaints register with resolution records
- Evidence of reportable incident notifications to NDIS Commission
- Evidence incidents and complaints inform improvement
Participant Files (sample)
- Service agreements
- Support plans aligned to NDIS goals
- Participant risk assessments
- Participants personal emergency preparation plans (where applicable)
- Evidence of participant involvement in planning
- Progress notes and daily records
- Consent records
- Health and safety information
- Restrictive practice authorisations (where applicable)
- Behaviour Support Plans (where applicable)
SIL-Specific Documentation
- Property compliance records (fire safety, accessibility)
- Emergency and evacuation plans for each property
- Mealtime management plans (where applicable)
- Overnight and active night support procedures
What Are Common SIL Certification Audit Failures?
First-time SIL providers commonly fail their certification audit due to these issues:
What Happens If You Get a Non-Conformity?
If the auditor identifies gaps in your compliance, they will record a non-conformity. There are two types:
Minor non-conformity
A gap exists but does not present immediate high risk. Common causes include documentation gaps, inconsistent implementation, or missing evidence of regular reviews.
- You must submit a Corrective Action Plan within 7 calendar days
- Implement corrections before your next scheduled audit
- The relevant standard will be reassessed at your next audit
Major non-conformity
A significant gap presenting high risk, or multiple minor non-conformities in the same module escalated to major.
- You must submit a Corrective Action Plan within 7 calendar days
- Implement corrections and undergo follow-up audit within 3 months
- Failure to close out within 3 months may prevent registration
For SIL providers, major non-conformities in restrictive practices or incident management are particularly serious given the participant cohort and risk profile.
How Much Does SIL Certification Audit Cost?
SIL certification audit costs vary depending on your organisation's size, number of SIL properties, and number of participants. Here are typical cost ranges:
Total first-year cost estimate: $10,000 to $30,000+
Larger organisations with multiple SIL properties will pay more due to additional site visits required during the audit.
Why You Need to Start Now for July 2026
1 July 2026 marks the start of the transition to mandatory SIL registration — it is not the date by which all providers must hold a Certificate of Registration. However, the NDIS Commission will publish specific deadlines by which unregistered providers must have completed registration to continue delivering SIL. Given registration takes 6 to 12 months, providers who have not started are already at risk of not being ready when those deadlines are set.
Here is why starting now matters.
Registration takes 6 to 12 months. If you have not started preparation, you are already behind.
Auditor availability is tightening. As the transition progresses, demand for NDIS auditors is increasing. Providers who wait may face significant delays securing an audit slot.
You need time to generate evidence. Auditors require evidence of implemented systems. You cannot create months of incident records, supervision documentation, and internal audit reports overnight.
The Commission has enforcement powers. Providers who continue delivering SIL without registration after the transition period ends face compliance notices, infringement notices, and banning orders.

Frequently Asked Questions
How long does SIL registration take from start to finish?
SIL registration typically takes 6 to 12 months from initial preparation to receiving your Certificate of Registration. The timeline depends on your starting point, the gaps in your current systems, and auditor availability. Providers with strong existing systems may complete faster; those starting from scratch should plan for the longer end.
What type of audit is required for SIL registration?
SIL registration requires a certification audit, which is the most comprehensive NDIS audit pathway. Certification audits involve two stages: Stage 1 (desktop review of documentation) and Stage 2 (on-site assessment at your SIL properties with staff and participant interviews).
How much does a SIL certification audit cost?
SIL certification audits typically cost $5,000 to $15,000+, depending on organisation size and number of SIL properties. Total first-year registration costs, including policy development, worker screening, and insurance, typically range from $10,000 to $30,000+.
What Practice Standards modules apply to SIL providers?
Most SIL providers must comply with the Core Module plus Module 1 (High Intensity Daily Personal Activities). If you implement Behaviour Support Plans or use restrictive practices, you must also comply with Module 2B (Implementing Behaviour Support Plans). New SIL-specific Practice Standards are being developed by the Commission and had not been finalised as of April 2026 — monitor the Commission website for updates.
What do auditors focus on most during SIL audits?
Auditors focus heavily on restrictive practices compliance, incident management, workforce governance (screening, training, supervision), participant rights and choice, and evidence that documented policies match actual practice.
What happens if I get non-conformities at my SIL certification audit?
For both minor and major non-conformities, your first step is the same: submit a Corrective Action Plan to your auditor within 7 calendar days of written notification. Minor non-conformities must be closed out within 18 months — if not, they escalate to major. Major non-conformities prevent registration from proceeding and must be closed out within 3 calendar months via a follow-up audit. If they are not resolved within that period, certification is automatically suspended.
Can I continue delivering SIL while my registration is in progress?
Transition arrangements are expected to allow providers who have commenced registration to continue delivering services while their application is processed. Specific details are subject to NDIS Commission guidance that had not been fully published as of April 2026. Monitor the Commission website at ndiscommission.gov.au for confirmed transition arrangements and do not assume you can wait until the last minute to act.
What is the difference between Stage 1 and Stage 2 audits?
Stage 1 is a desktop review where the auditor assesses your documentation remotely. Stage 2 is an on-site assessment where the auditor visits your SIL properties, interviews staff and participants, reviews files, and verifies that your documented systems match actual practice.
How many site visits will auditors conduct for SIL registration?
Auditors typically visit multiple SIL properties during a certification audit. The number of visits depends on how many properties you operate and how many participants you support. Expect at least one visit per property, or a representative sample for larger providers.
What is the most common reason SIL providers get non-conformities?
The most common non-conformities for SIL providers involve restrictive practices (used without authorisation or a current Behaviour Support Plan), incident management (incidents not investigated or corrective actions not documented), and workforce governance (gaps in screening or supervision records for casual and agency staff).
