Every performance audit in progress on the ANAO website has a panel inviting the public to contribute. The panel tells you that "you will not automatically receive feedback about your contribution", that "contributions are intermittently monitored", and that you may upload one file of up to 8 MB. At 11 October 2026, 21 audits were open for contribution.
What happens to those contributions is not recorded anywhere public. In 25 annual reports, 2001-02 to 2025-26, the ANAO has not once published how many it received or what came of them. Four state audit offices and the UK National Audit Office publish how many approaches they receive. The UK office also reports how many whistleblowing disclosures it received and how many it acted on.
