The ANAO could assess the National Disability Insurance Agency (NDIA’s) debt management and recovery processes, and its administration of compensation recovery and reduction amounts. A debt can arise and be recovered where a National Disability Insurance Scheme (NDIS) payment is made to a person or organisation not entitled to it. For example, where a NDIS participant or provider makes a mistake in their claim or makes a false claim. In 2024–25 the NDIA reported a historical scheme debt provision of $6.3 million. In August 2025, the NDIA completed a review of its debt management policies and practices and found errors in the way it handled some historical participant and provider debts, which it revoked or refunded. The NDIA is progressing system and policy improvements through its Crack Down on Fraud and Payment Integrity programs. Amendments to the National Disability Insurance Scheme Act 2013 made in October 2024 allow the NDIA to apply more flexible debt waivers to protect participants.

For some participants entitled to NDIS payments, separate compensation is also payable for the cost of supports they need due to personal injury causing their impairment. The NDIA may recover specific compensation amounts from participants, compensation payers or insurers to avoid duplication in support funding. In 2024–25 the NDIA reported compensation receipts of $69.2 million. The NDIA may separately apply a compensation reduction amount (CRA) to a participant’s plan, reducing their entitlement to future NDIS support funding. A CRA is not a debt owed to the NDIA. In relation to compensation recovery, NDIS legislation allows the NDIA to seek compensation on a participant’s behalf and allows it to decide not to recover compensation in special circumstances.
