Frequently asked questions
What is the difference between a verification and a certification NDIS audit?
Verification is a single desktop review for lower-risk supports such as plan management or sole-practitioner therapy. Certification is a two-stage audit — a document review then an onsite assessment — for higher-risk supports like SIL, personal care, high-intensity daily activities and Specialist Disability Accommodation, plus a mid-term surveillance audit around 18 months. The Commission assigns your pathway based on your registration groups, so confirm it on your registration record.
How often do NDIS providers get audited?
Registration runs in three-year cycles. Verification providers are audited at registration and again at each three-year renewal. Certification providers have an initial two-stage audit, a mid-term surveillance audit at roughly 18 months, and a recertification audit before the three-year registration expires. Higher-risk and high-intensity providers may face tightened cycles as the Commission's expanded enforcement powers roll out.
How much does an NDIS audit cost?
Auditors set their own fees, so costs vary widely. Verification audits are cheaper because they are desktop-only; certification audits cost more due to two stages, onsite time and a mid-cycle surveillance audit, and fees rise with your number of registration groups, sites and workers. Get written quotes from several approved quality auditors for your exact scope, and budget for preparation time and system upkeep as well.
What are the most common reasons providers fail an NDIS audit?
The frequent non-conformities are missing or unsigned service agreements, undocumented consent, expired worker screening clearances, and incident or complaints registers that are empty or under-used. Stale risk registers, no evidence of continuous improvement, and unmanaged conflict of interest also recur. Most are documentation and consistency failures, not deep operational problems, which is why a self-assessment and mock file review before the audit catch the majority of them.
Do SIL providers face new audit requirements in 2026?
Yes. From 1 July 2026, SIL and digital-platform providers face mandatory registration, with a new registration group 0138 (Assistance with SIL) and a SIL Supplementary Module of the Practice Standards. Existing SIL providers are assessed against the new module at their next scheduled audit, so add it to your self-assessment now. Confirm the module's exact content on ndiscommission.gov.au, as these changes are still being implemented.
