How to find an NDIS-approved quality auditor

The official directory

The NDIS Quality and Safeguards Commission publishes the full list of Approved Quality Auditors on its website. This is the only list you should pick from - audits done by anyone not on this list are not recognised.

How to shortlist

The directory lists everyone approved nationally. Most auditors operate across multiple states. Filter your shortlist by:

• Service-type experience. SIL, SDA, behaviour support, and early childhood each have specialist evidence requirements. An auditor who's done 50 SIL audits will be faster and more decisive than one for whom you're their first.
• State coverage. Auditors with offices in your state usually charge less for site visits (less travel time billed to you).
• Tier match. Some auditors specialise in verification audits (Tier 2, lower-risk groups); others run certification audits (Tier 1, including SIL). Confirm the auditor handles the tier you need before you book.

What to ask before signing

Get quotes from 2-3 auditors on your shortlist. The Commission doesn't fix audit prices - they're commercially negotiated. Reasonable questions:

• What's your fixed-price quote for [verification / certification] with [N] registration groups, [N] participants in your sample?
• Are travel + site-visit days included, or billed separately?
• How much lead time do you need to book a Stage 1 desk audit? Stage 2 site visit?
• What's your typical turnaround from final document submission to audit report?
• What happens if I don't pass first time - is a corrective- action follow-up included, or charged separately?
• How do you prefer to receive evidence - secure portal, USB, cloud share?

Realistic budget

For a small-to-medium provider:

• Verification audit: A$1,500-3,500 (desk-based document review)
• Certification audit: A$8,000-15,000+ (Stage 1 desk + Stage 2 site visit + report)
• Add-ons: travel (if state-mismatched), corrective-action re-review (if findings)

How Checkbase helps

When you're ready to share evidence with your chosen auditor, Checkbase generates a secure, time-boxed link with 6-digit OTP verification - they don't need a Checkbase account, just the link. Every access is logged for your audit trail. Combined with the one-click Tier 1 Evidence Pack PDF, your auditor gets a complete, organised evidence bundle in a couple of minutes instead of zip files emailed back and forth.
