The word “audit” can send a shiver down anyone’s spine, but in the NDIS landscape, it shouldn’t be a source of fear. The National Disability Insurance Scheme is heavily regulated to protect public funds and ensure safety, meaning checks and balances are built directly into the system.

If you are plan managed, your plan manager handles the heavy lifting of processing invoices, claiming funds through the myplace portal, and keeping formal financial ledgers. However, the NDIA (and the NDIS Quality and Safeguards Commission) can still request evidence directly from participants to ensure funds are being spent transparently.

To protect your funding pool and maintain complete peace of mind, there are specific records you must personally keep. Here is your ultimate guide to audit-proofing your personal NDIS records using Australian record-keeping standards.

1. Signed Service Agreements

A service agreement is more than a casual piece of paper; it is your ultimate legal shield. When an auditor asks why a provider was paid a specific rate, this document provides the formal justification.

You must personally keep copies of all current and historical agreements. A properly structured contract outlines exactly what supports will be delivered, hourly costs, travel allowances, and cancellation policies. Having these systematically filed proves that your spending was planned and collaborative. If you haven’t formalised your arrangements yet, check out our guide on what an NDIS service agreement is and why you need one to get your compliance up to scratch.

2. Receipts and Proof of Purchase for Out-of-Pocket Expenses

While your plan manager pays your standard provider invoices directly, there are many instances where you might pay for an item out of pocket and request a reimbursement. This is incredibly common when purchasing low-cost aids, tools, or consumable items.

If you claim a reimbursement, you must retain the original retail tax invoice or receipt. Auditors look specifically at these items to ensure that the goods purchased directly relate to your disability goals. For example, if you purchased sensory items or kitchen modifications, your receipt must be filed safely alongside the logic of how it benefits your day-to-day life. This rule is highly relevant when managing your budget for low-cost assistive technology and small aids under $1,500, where individual store receipts act as your main source of compliance.

3. Logbooks and Kilometre Trackers

Transport and travel billing are under intense scrutiny by the NDIA. If your providers or support workers charge you for provider travel (the cost of driving to you) or participant transport (driving you to an activity), you should maintain a personal logbook.

Your log tracking should record:

• The date of the shift.
• The starting location and destination.
• The total kilometres travelled.
• The name of the support worker or provider.
•  

Cross-referencing your personal travel logs against your provider’s invoices ensures you are only billed for actual distances covered. It also helps you stay fully compliant with your overall NDIS transport funding support levels, preventing overclaims that might trigger an administrative red flag.

4. Professional Progress Reports and Clinical Evidence

Audits aren’t just about financial numbers; they are also about tracking outcomes. The NDIA wants to see that the services you buy are actually helping you achieve the goals listed in your plan.

Make it a habit to request and store annual or biannual progress reports from your Allied Health professionals—such as your Occupational Therapist, Physiotherapist, or Speech Pathologist. If an auditor questions why you spent thousands of dollars on a specific therapy program, a clinical report proving your physical or cognitive development serves as definitive justification.

How Long Do You Need to Keep NDIS Records?

Under Australian taxation and NDIS compliance guidelines, you should keep all your relevant invoices, receipts, agreements, and support logs for a minimum of 5 years. Keeping a simple digital folder on your computer or scanning physical documents into an app is the easiest way to ensure these records remain readable and organised over time.
