Why the procedure is a separate document

Under Practice Standard Outcome 1.5, providers are required to have an accessible complaints system. The Quality Indicators behind 1.5 split into two evidence categories: commitment (policy) and operational delivery (procedure + register + records). Auditors check both.

The Complaints Policy is the participant-facing document — it says what rights the participant has, what we promise to do, how they can complain, and where they can escalate. The Complaint Handling Procedure is the internal staff-facing document — it walks the support worker or manager through exactly what to do when a complaint comes in, in what order, with what timeframes, and what to log. The policy goes in the participant handbook; the procedure goes in the staff induction pack.

The 8 mandatory steps

Across the NDIS Commission's complaint-handling guidance and the audit non-conformance patterns we cover in our non-conformance guide, eight steps consistently show up in procedures that pass audit. Templates that skip any of these steps get flagged.

Step 1
Receive the complaint
Any staff member who receives a complaint — verbally, in writing, by phone, by email, via a third party — must accept it without filtering, defending the organisation, or asking the complainant to use a different channel. The procedure should list at least three accessible channels (in person, phone, email/written) and note that complaints can come from participants, families, advocates, nominees, support workers, or anyone else.
Step 2
Acknowledge within 2 business days
The staff member or manager acknowledges receipt in writing within 2 business days. The acknowledgement confirms what was complained about (in the complainant's words, not paraphrased), names the person who will manage the resolution, sets a target resolution date, and includes the NDIS Commission contact details (1800 035 544) for external escalation if needed.
Step 3
Log to the Complaints Register
Every complaint — including verbal complaints that get resolved on the spot — gets logged. The register entry includes date received, complainant name (or "anonymous" with reason), nature of complaint, who handled it, resolution timeline, outcome, and any continuous improvement action arising. See our complaints register guide for what the register itself must contain.
Step 4
Triage by seriousness
Most complaints are managed under the standard 30-day resolution pathway. Some trigger parallel processes: anything involving alleged violence, abuse, neglect, exploitation or discrimination (VANED) is also a safeguarding event under the same Practice Standard Outcome 1.5. Anything involving a reportable incident also triggers the incident-management procedure. The procedure must show staff how to identify these triggers and run the parallel pathway alongside complaint resolution.
Step 5
Investigate
The named manager investigates: interviews the complainant in their preferred format, reviews relevant records (shift notes, incident reports, participant file), interviews staff named in the complaint, and identifies any contributing factors or root causes. Investigation steps and findings are documented in the complaints register entry, not just held verbally.
Step 6
Propose resolution and communicate
The manager proposes a resolution to the complainant in their preferred communication format. Resolution can include: explanation, apology, change of staff, change of process, service-credit, or referral elsewhere. The complainant gets the opportunity to accept or reject; if they reject, the procedure escalates to internal review and external pathway.
Step 7
Implement and follow up
If the resolution involves a process change (most do), the change goes into the Continuous Improvement Register with a review date 1–3 months out. The complainant is followed up at that review date to confirm the change has held. The register entry is closed only after the follow-up confirms resolution.
Step 8
Inform of external pathway
At every step — and especially if the complainant is dissatisfied with the outcome — the procedure requires staff to inform the complainant of the NDIS Quality and Safeguards Commission complaint pathway (phone 1800 035 544, online form). This is non-negotiable under NDIS (Provider Registration and Practice Standards) Rules 2018. Auditors check that the written acknowledgement, the resolution letter, and the service agreement all include the Commission contact.

Serious complaints (VANED, reportable incident triggers) override these standard timeframes — they require immediate response, parallel notification to the NDIS Commission within 24 hours if a Reportable Incident, and the standard 30-day resolution clock still runs alongside the incident-management process.

NDIS Commission escalation pathway

Every NDIS-registered provider must inform participants and their nominees/advocates that they can complain directly to the NDIS Quality and Safeguards Commission at any time — they don't need to use the provider's internal process first. The Commission contact details are: 1800 035 544 (free call), or online via ndiscommission.gov.au/about/complaints.

The procedure template must include these details in at least three places: the participant-facing complaints policy (which is part of the service agreement pack), the staff procedure (so staff can quote the details when asked), and the written response sent to any complainant. Auditors check all three — missing any one is a finding.

The Complaint Handling Procedure and the Complaints Register are paired documents. The procedure tells staff what to do; the register is where they record it. The audit evidence trail runs across both:

If the procedure references the register but the register doesn't show the entry, the auditor finds a policy-practice gap. This is the most common non-conformity pattern across all Outcomes — staff know the procedure, but the evidence trail isn't completed in the register. The procedure template must explicitly tell staff which fields to fill in, in what order.

Serious complaints — the parallel pathway

Some complaints are also reportable incidents under the NDIS Act 2013. When a complaint alleges: death or serious injury, abuse or neglect, sexual misconduct, unauthorised use of restrictive practices, or other Reportable Incidents per the Act, the provider must notify the NDIS Commission within 24 hours (immediate for death/serious injury) in addition to running the standard complaint resolution.

The Complaint Handling Procedure must signpost staff to the Reportable Incidents procedure at Step 4 (triage). Doc 62 (Reportable Incident Quick Reference) in our kit is the bedside-card version of this — staff can check whether a complaint also triggers reportable status without re-reading the full procedure each time.

Common mistakes in complaint procedures

  1. Procedure references the policy without restating the steps. "Refer to Complaints Policy" is not a procedure. Staff need step-by-step instructions, not a policy redirect.
  2. No timeframes in the procedure body. "Promptly" and "as soon as possible" are not auditable. 2 business days, 30 days, quarterly — these are the numbers auditors check.
  3. Missing NDIS Commission contact details in the written acknowledgement template. The acknowledgement letter template that comes with the procedure must include 1800 035 544.
  4. No triage step for serious complaints. If the procedure doesn't tell staff how to identify a Reportable Incident hiding inside a complaint, those reports get missed and the Commission penalty for a missed Reportable Incident is much larger than the complaint itself.
  5. Register entries not closed-the-loop. Resolution date is filled in but follow-up date is empty. The auditor opens the register, picks the oldest open entry, and asks why follow-up wasn't done.
  6. Anonymous complaints rejected. The procedure must accept anonymous complaints. Templates that say "complainant identification required" fail Outcome 1.5.

For the day-to-day note-writing that proves staff are following the procedure — incident notes, complaint follow-up notes, supervision discussions about complaints — the free NDIS Notes Rewriter rewrites rough notes into Practice-Standards-aligned language. Staff who write good complaint-related notes generate audit evidence as a by-product of doing the job; staff who don't, force the manager to reconstruct the evidence trail after the fact.

If you're building a complete complaint-handling system from scratch, the procedure is one of about five inter-locking documents. Our cornerstone SIL Audit Survival Guide walks through how the policy, the procedure, the register, the form, the participant rights statement, and the service agreement all stitch together to satisfy Outcome 1.5.
