Updated Australian guide for 2026
How much does an NDIS audit cost?
There is no government-set audit price. Your quote depends on the audit type, registration groups, organisation size, participants, locations and required audit activity.
An NDIS quality audit assesses a provider against the NDIS Practice Standards applicable to its registration. The audit is conducted by an independent approved quality auditor—not by the NDIS Commission or your compliance consultant.
The current page previously gave broad fixed ranges that could not reliably apply to every provider. A useful audit-cost guide should instead explain the required audit type, what changes the auditor’s workload and how to compare quotes on equivalent scope.
This page focuses on audit fees. Read our NDIS registration cost guide for application, compliance setup, insurance and ongoing expenses.
NDIS audit types and how they affect cost
Verification audit
A desktop review for providers delivering lower-risk or lower-complexity supports. The auditor reviews required documentary evidence.
Certification audit
A two-stage assessment that includes desktop review and onsite activity, with records, sites, workers and participant involvement where applicable.
Mid-term audit
Applies to many certification providers and focuses on governance, operational management and relevant corrective-action areas.
Condition or out-of-cycle
May be required because of registration conditions or changes such as adding registration groups or expanding service delivery.
| Audit type | General purpose | Potential cost drivers |
|---|---|---|
| Verification | Initial application or renewal for applicable lower-risk supports. | Document quantity and quality, professional evidence, registration groups and clarification required. |
| Certification | Initial application or renewal involving applicable higher-risk or complex supports. | Modules, stages, participants, workers, sites, interviews, observations, travel and organisation scale. |
| Mid-term | Assessment during the registration period for applicable certification providers. | Scope, governance evidence, corrective-action areas, participant and site activity. |
| Condition | Audit required by a registration condition or Commission direction. | Specified scope, timing, outstanding matters and evidence required. |
| Out-of-cycle | Supports a change to registration, such as added groups or service expansion. | New standards, modules, locations, supports and implementation evidence. |
| Renewal | Audit forming part of the registration renewal process. | Current scope, changes, provider growth, audit type, evidence and sites. |
What determines an NDIS audit quote?
- Initial scope of audit: the standards, modules, registration groups and delivery types to be assessed.
- Verification or certification: certification normally involves more extensive assessment activity.
- Organisation size and scale: workforce, participant numbers, governance structure and service volume.
- Sites and geography: the number and location of offices and service-delivery sites, including travel.
- Participants and workers: audit sampling, interviews and records reviewed.
- Service complexity: higher-risk and specialist services can require additional modules and technical expertise.
- Audit duration and team: required auditor days and whether specialist auditors are involved.
- Readiness and evidence: missing, disorganised or unclear records can increase clarification and follow-up effort.
- Nonconformities: corrective actions and further evidence may affect the final amount depending on quote terms.
What should an audit quote explain?
Ask the approved quality auditor to clearly identify:
- The audit type, scope, modules and registration groups included.
- Stage 1 and Stage 2 activity where certification applies.
- Expected auditor days, onsite activity and remote work.
- Travel, accommodation, mileage and other disbursements.
- Participant interviews, site sampling and specialist expertise.
- Report preparation and factual-accuracy review.
- How minor or major nonconformities and follow-up are charged.
- Cancellation, rescheduling and scope-change fees.
- GST and payment milestones.

How to obtain a more accurate audit quote
- Complete the registration or renewal application accurately.
- Obtain the official audit-scope document issued for the application.
- Send the same complete information to several approved quality auditors.
- Disclose current workforce, participant numbers, locations and service delivery.
- Ask every auditor to state assumptions, exclusions and variable charges.
- Compare total scope and terms—not only the headline price.
- Confirm the auditor’s current approved status before engagement.
Audit fees versus audit-preparation costs
The independent auditor’s fee should be distinguished from consultancy, document development and internal readiness work. An auditor assesses conformity and must remain independent. A consultant may help the provider understand requirements, assess gaps and prepare evidence, but should not present itself as the independent approved quality auditor unless separately authorised and acting within the applicable framework.
| Independent audit fee | Audit-preparation cost |
|---|---|
| Assessment by an approved quality auditor. | Internal or external work to understand requirements and address gaps. |
| Audit planning, evidence review, interviews, visits and reporting. | Policy tailoring, registers, training, file reviews and implementation support. |
| Formal findings and recommendation to the Commission. | Readiness feedback and corrective-action assistance before or after audit. |
| Must remain independent from consultancy conflicts. | Does not replace the provider’s responsibility or guarantee an outcome. |

Frequently asked questions
How much does an NDIS audit cost?
There is no universal price. Approved quality auditors set their own fees based on audit type, scope, registration groups, organisation size, participants, sites, service complexity, travel and follow-up requirements.
Does the NDIS Commission charge for the audit?
No. The provider engages and pays an independent approved quality auditor. The Commission does not set audit-service prices.
Is a verification audit cheaper than certification?
Verification is generally a desktop review for lower-risk supports, while certification involves more extensive two-stage assessment. However, obtain quotes for your actual scope rather than relying on a general assumption.
What is included in a certification audit?
Certification involves Stage 1 document review and Stage 2 onsite assessment. Depending on scope, the auditor may review records, visit sites, interview staff and participants and observe service delivery.
When is a mid-term audit required?
It applies to many providers that completed certification for higher-risk or complex supports. The Commission identifies exceptions, so providers should confirm their own requirements and dates.
Are consultant fees included in the audit quote?
Generally, consultancy and readiness support are separate from the independent audit. Confirm the auditor’s quote inclusions and maintain appropriate independence between roles.
How many audit quotes should I obtain?
The Commission encourages providers to obtain and compare multiple quotes. Give each auditor the same scope and organisation information to support a fair comparison.
Can a consultant guarantee that I will pass?
No. A consultant can support readiness and implementation, but cannot guarantee an independent audit result or the Commission’s registration decision.
