The full answer
Stage 2 is the high-stakes on-site audit. Preparation: 1) Run a full mock audit 7-14 days before (use NDIS Quality Indicators Workbook as your checklist), 2) Fix everything the mock reveals, 3) Brief every staff member on what auditors will ask — likely questions about participant rights, incident management, practice standards, 4) Organise your evidence binders (physical or digital) by module with clear tabs, 5) Prepare participant and family contact information for interviews (auditors will speak to ~20% of participants), 6) Ensure progress notes are current and match service agreements, 7) Test your key systems (invoicing records, Worker Screening status, training records) work in real time. On the day: welcome auditors warmly, give them a quiet workspace, answer questions directly (don't spin), and be available for follow-up questions. Most audit failures come from poor staff briefing or sloppy evidence organisation.
