In short, you should realistically budget $900 to $1500 for a Verification audit, and $7000 at the low end for a full Certification audit.
First, the good news: the application itself is free.
The NDIS Quality and Safeguards Commission does not charge an application fee. You submit your registration application through the Commission’s online portal at no cost.
Almost everything after that point, however, costs money.
The figures below are estimates based on my experience working in NDIS audits and audit administration, and based on small providers delivering supports to a small number of participants. They’re a starting point for planning, not a substitute for real quotes! Audit pricing varies between auditors and changes over time, so always get at least three quotes before committing to anything.
Verification audits: consistent pricing, clear scope
If your registration groups only include lower-risk supports (e.g. therapeutic supports, household tasks, or transport) you’ll be assessed via the Verification pathway. This covers four practice standards: Incident Management, Complaints Management, Human Resources Management, and Risk Management.
Verification audits are desktop reviews. The auditor assesses your documentation remotely, meaning there are no site visits and no participant interviews required under the audit methodology. The audit takes roughly the same amount of time regardless of whether you’re a sole trader or a small team. Most auditors have a set price for Verification.
Realistic budget for a Verification audit: $900 to $1,500.
You might see prices above this range for a couple of reasons. Some auditors may not have much capacity for Verification work (it’s not very profitable relative to the administration time involved) and price accordingly. Others may charge a higher price for faster turnaround. Neither necessarily reflects audit quality, but worth keeping in mind as you get quotes.
Certification audits: why the published ranges can be misleading
This is where the conversation starts to get more complicated.
You’ll see figures like “$3,000 to $10,000+” quoted for Certification audits. That range is technically accurate but not particularly useful, as the factors that move your cost within that range are what matter, and they’re rarely explained. If you ask for a ballpark quote from auditors over the phone, don’t expect to get an answer immediately – it takes a lot of work to calculate audit requirements and duration.
Certification audits involve two stages, mandatory site visits, participant and worker interviews, and file reviews. The audit methodology is set by legislation and the minimum time required to meet it is not trivial. When you work through what a proper Certification audit actually involves for even a small provider, the lower end of published ranges starts to look optimistic.
My honest starting point for a Certification (Stage 1 and Stage 2) audit: $7,000 for a small provider with a handful of staff and participants, assessed against the Core Module only.
For new providers who haven’t yet started delivering services, there is a lower-cost entry point, but it comes with conditions.
Provisional certification: the cheaper starting point (with caveats)
A provisional audit is available to providers who have built their systems and are ready to register, but haven’t yet started delivering supports to any NDIS participants.
Because there are no participants, the normal sampling requirements don’t apply, as there are no participant files to review and no participant interviews to conduct. A provisional audit can also be conducted by a single auditor (rather than the two required for a full Certification), and the Stage 1 and Stage 2 can be combined into a single visit. This makes it meaningfully cheaper than a full Certification audit.
Realistic budget for a provisional Certification audit: starting at $4-5k for a small, Core Module only assessment.
However (and this is important), a provisional audit produces a qualified certification decision, not a full one. Once you start delivering services, a further Stage 2 audit is required. Many providers don’t realise this when they budget. That follow-up audit, even for a small provider, is likely to cost an additional couple of grand at a minimum.
Common misconception: Providers sometimes think a provisional audit is available because they’re currently unregistered. The trigger isn’t your registration status, it’s whether you have any participants. If you already have participants (even as an unregistered provider), a full Stage 1 and Stage 2 is required.
What drives Certification costs up
Understanding why Certification costs vary requires a brief look at how auditors are required to approach the audit.
The NDIS audit methodology (set out in legislation) requires auditors to interview participants, review participant files, interview workers, and attend sites. The minimum sample sizes are not arbitrary, they’re calculated using a square root formula based on your participant and site numbers. An auditor cannot simply decide to review fewer files to finish faster.
What this means in practice is that your audit cost scales with your organisation:
- More participants → larger minimum sample → more audit time → higher cost
- More sites → more site visits required
- More staff → more worker file reviews and interviews
- More supplementary modules → additional standards to assess → more time
Supplementary modules
Providers delivering higher-risk supports are assessed against the Core Module plus one or more supplementary modules. Each one adds to the audit scope, and therefore the cost.
The cost impact varies significantly by module. High Intensity Daily Personal Activities for example covers eight distinct service types (complex bowel care, ventilator support, subcutaneous injections, enteral feeding, and others). If you deliver only one of those service types, the addition to your audit might be modest, but if you deliver all eight, it’s potentially more substantial.
Budget $1-2k for each supplementary module, at a minimum. That figure increases if you have participants receiving those services already, and again if they’re receiving these services at multiple sites, since the legislation requires prioritising the highest-risk registration groups for sampling.
There’s also a practical consideration for High Intensity Daily Personal Activities specifically: this module can only be assessed by a registered nurse. Registered nurse auditors are in demand and limited in supply. For Certification audits involving this module, your audit team may consist of three people rather than two, and that’s going to be reflected in the price.
The audit cycle: not as simple as every three years
This is a widely misunderstood aspect of NDIS registration costs, and it affects your long-term financial planning significantly.
Most providers believe they’ll have one audit, then another audit three years later. That’s not quite how it works.
Your three-year registration period doesn’t start when your audit is completed. It starts when the NDIS Commission approves your registration, which can be six to twelve months after your audit submission, sometimes longer (although the latest Quarterly Report does show this timeframe is decreasing). The Commission’s processing time is outside your auditor’s control and difficult to predict.
Within your registration period, you’ll also have a mid-term audit, due 18 months after your registration approval date. Your recertification audit is then due before your registration expires – again measured from the Commission approval date, not the audit date. When your recertification is approved, the clock resets from that new approval date.
Practical advice: Once you receive your Certificate of Registration, contact your auditor (or consider whether you want to select a new auditor) to book a tentative mid-term date. The 18-month window can approach faster than expected, and good auditors fill up quickly.
Mid-term audits: don’t underestimate them
Mid-term audits use reduced sampling requirements under the legislation, so they’re lighter than a full recertification. But lighter is relative.
Every non-conformity from your previous Certification audit must be fully reviewed again at the mid-term. If you had findings to address, those add time regardless of the reduced sampling.
Minimum budget for a mid-term audit (very small provider, fully conforming previous audit): $5,000.
A significant portion of audit cost is administration and report-writing time, not just on-site time. This is why mid-term audits tend to cost more than providers expect.
NDIS Worker Screening
Every worker in risk-assessed roles must hold a current NDIS Worker Screening clearance. For most providers, this isn’t a large upfront cost, as many workers already in the disability sector will hold one. But for new providers building a team from scratch, it’s worth budgeting for.
Screening fees vary by state and territory, but currently sit between $100-160 depending on your state/territory.
Worth knowing: Clearances are portable. A worker who already holds a clearance doesn’t need a new one when they join your organisation.
Documentation costs
Your audit assesses whether your policies and procedures reflect how your service actually operates. This is not a trivial requirement. Auditors are very good at identifying documentation that describes a generic business rather than the actual provider in front of them.
The cost of getting your documentation right depends entirely on the approach you take: hiring a consultant, purchasing templates and rewriting them to fit your service, or using a tool that generates documents from your own answers. Whatever approach you choose, documentation is a real cost that deserves a line in your budget. Don’t leave it until after your audit scope arrives.
Other costs to factor in
This article focuses on audit and compliance costs specifically, but becoming a registered NDIS provider involves a few other expenses that you should keep in mind:
- Business registration: sole trader setup is minimal, but company registration typically $500 to $1,500
- Insurance: public liability and professional indemnity are generally required, costs vary quite a lot by service type and coverage level. Don’t forget WorkCover if you’re bringing on staff.
- NDIS software: rostering, invoicing and claiming tools can range from free basic options to a few hundred dollars per month depending on your service size
- Worker Orientation Module: free, but factor in the time cost for each worker
These vary too much to generalise, but if you’re not already set up as a business, you should budget at least a few thousand dollars on top of your audit and documentation costs when planning your registration.
Getting audit quotes
When you submit your registration application, the Commission sends you an Initial Scope of Audit document. This is what you take to Approved Quality Auditors to request quotes. The scope sets out which practice standards apply to your registration groups and which audit pathway is required.
Get at least three quotes. The price variation across auditors is real, and so is the variation in quality. Ask each auditor how they determine audit duration, how many auditors will be on your team, and how they handle non-conformities. The answers (and their willingness to answer) will tell you a lot about what you’re buying.
Cheaper is not always better, and that rings very true here. A proper audit that finds real gaps, if there are any, is worth far more than a fast one that doesn’t.
