Common Mistakes in an NDIS Feedback and Complaints Register

Why Your Feedback and Complaints Register Is Under Scrutiny in 2026

The strengthened NDIS Practice Standards — progressively applied to registered providers through the 2024–2026 cycle — place renewed emphasis on how providers receive, record, and act on feedback and complaints. For SIL (Supported Independent Living) providers, who deliver some of the most intensive support environments under the NDIS, a well-maintained feedback and complaints register is not optional paperwork. It is direct evidence that a provider takes participant voice seriously and meets the Commission's expectations under the Feedback and Complaints Management core module.

Approved quality auditors assess your register as a primary artefact. Gaps in it generate non-conformances that can trigger corrective action plans, delay registration renewal, or — in serious cases — lead to conditions being placed on your registration. Below are the most common mistakes SIL providers make in their register, along with practical fixes for each.

Mistake 1: Recording Only Formal Written Complaints

Many providers interpret "complaints register" too narrowly and only log written grievances submitted through a formal process. In practice, the NDIS Practice Standards require providers to capture all feedback — positive, negative, and neutral — along with complaints regardless of how they were received: verbally, in writing, via a support coordinator, or through an advocate.

The Fix

• Define "complaint" broadly in your policy to include verbal expressions of dissatisfaction, concerns raised by families or guardians, and issues raised by support coordinators on a participant's behalf.
• Train all frontline workers to recognise feedback moments and refer them to the designated complaints handler for logging.
• Add a column to your register for receipt channel (verbal, email, phone, in person, via advocate) so auditors can see the breadth of capture.

Mistake 2: Omitting Anonymous Feedback

The NDIS Commission expects providers to offer accessible avenues for feedback, including anonymous options. A register that contains zero anonymous entries over a 12-month period is a red flag for auditors — it suggests either that staff are not offering the option or that participants do not feel psychologically safe raising concerns under their name.

The Fix

• Create a simple anonymous feedback form (paper or digital) and make it visibly available in common areas and participant communications.
• Log anonymous entries in the register with a notation such as "Anonymous — verbal via suggestion box" and record the action taken even when a complainant cannot be personally notified of the outcome.

Mistake 3: No Documented Resolution Timeframes or Outcomes

A register that records complaints received but not resolved is incomplete and non-conformant. The NDIS Practice Standards require providers to acknowledge complaints promptly, investigate them, and advise the complainant of the outcome. Without documented timeframes and outcomes in the register, there is no evidence that this process actually occurred.

The Fix

Your register should include, at minimum, the following columns:

Mistake 4: Conflating Complaints with Incidents

These are distinct obligations under the NDIS regulatory framework. An incident involves an event that caused harm or risk to a participant and is governed by the NDIS Commission's incident management requirements, which include mandatory reportable incident notifications. A complaint is an expression of dissatisfaction about a service, support, or experience. Mixing the two in a single log — or worse, handling a complaint purely as an incident — means you may miss the response obligations specific to each pathway.

The Fix

• Maintain separate registers: one for incidents (linked to your incident management system and reportable incident obligations) and one for feedback and complaints.
• Where a complaint also involves an incident, create linked records in both systems and document the cross-reference.
• Brief all team leaders on the triage decision: "Is this a safety event requiring incident management, a participant complaint, or both?"

Mistake 5: No Evidence of Governance Review

The NDIS Practice Standards require that complaint data informs quality improvement. A register that is created and filed away without any evidence of periodic review at management or governance level fails this requirement. Auditors specifically look for meeting minutes, quality committee records, or management reports that demonstrate the register data was analysed and acted upon.

The Fix

• Schedule quarterly complaints review as a standing agenda item at your quality committee or Board/management meeting.
• Produce a brief summary report each quarter: total complaints received, categories, resolution times, themes, and improvement actions initiated.
• Attach these summary reports to your meeting minutes and retain them as evidence of systemic oversight.

Mistake 6: Inaccessible Complaint Processes for Participants

A register can only be as good as the process feeding it. If participants — many of whom may have complex communication needs, low literacy, or English as a second language — cannot practically access your complaint process, the register will not reflect the true level of concern in your service. The NDIS Commission's approach under the strengthened standards emphasises participant voice, accessibility, and the right to be supported by an advocate.

The Fix

• Provide your complaints process in Easy Read format and, where relevant, in participants' preferred languages.
• Remind participants of their right to contact the NDIS Commission directly (1800 035 544) at every complaints interaction.
• Document that participants were made aware of independent advocacy options such as the National Disability Advocacy Program.
• Include a field in your register noting any communication support or adjustments provided during the process.

Mistake 7: Failing to Identify and Act on Systemic Issues

Individual complaints handled in isolation miss the point of a register. The NDIS Quality and Safeguards Commission expects providers to identify patterns — recurring complaint categories, specific sites or staff generating repeated concerns, or particular support types that attract dissatisfaction — and to address the root cause rather than just the individual case.

The Fix

• Categorise every entry by complaint type (e.g., communication, support quality, rostering, participant rights, restrictive practices).
• Run a frequency analysis at least quarterly to detect patterns.
• When a pattern emerges, initiate a formal improvement action and document it in both the register and your quality improvement log.

A Practical Step-by-Step: Auditing Your Own Register

1. Pull the register for the last 12 months and confirm every entry includes: date received, receipt channel, nature of complaint, parties involved (de-identified where appropriate), acknowledgement date, investigation notes, outcome, and closure date.
2. Check for anonymous entries. If there are none, assess whether your process genuinely offers anonymous pathways.
3. Verify no incidents have been logged as complaints only — cross-reference against your incident register.
4. Locate governance review evidence — at least two quarterly review records in the past 12 months.
5. Check that complainants were notified of outcomes for all closed entries. Open entries beyond your stated resolution timeframe need escalation notes.
6. Confirm accessibility provisions are documented for participants who required additional support.

Getting Audit-Ready for 2026

With the 2026 mandatory registration requirements tightening obligations on SIL and other high-intensity support providers, having a complaints register that passes auditor scrutiny is no longer a stretch goal — it is a baseline. Providers who have historically treated the register as a filing formality are at real risk of non-conformance findings during their next audit cycle.

If you are preparing for your audit across the full range of NDIS Practice Standards obligations — not just complaints management — ndiscompliant.com.au offers a 136-document SIL compliance kit designed specifically for this purpose, covering everything from incident management to restrictive practices and participant rights.

The most important thing you can do right now is open your current register, run the six-step self-audit above, and document what you find. Approved quality auditors will do exactly the same — and they will want to see that you did it first.
