Public Interest Disclosure

The Public Interest Disclosure Act 2018 (PID Act) commenced on 1 July 2019, replacing the Whistleblowers Protection Act 1993. The Act provides greater protection for informants and improves transparency and accountability in government and public sector.

The PID Act applies differently to the following two types of public interest information:

  1. Environment and health information - protection for anyone wanting to disclose environmental and health information where there is a substantial risk to the environment or to public health and safety.

  2. Public administration information - protection for public servants wanting to disclose administration information where there is potential corruption, misconduct or maladministration.

How to protect yourself?


To gain the protections under the PID Act, you must make an appropriate disclosure of public interest information.
