The Act affects multiple classes of people and entities, with different rules and duties depending on the role.
Informants. Any person who makes an appropriate disclosure of public interest information is an informant under the Act (s 4). That includes private individuals disclosing environmental and health information (subject to the belief thresholds in s 5(3)) and public officers disclosing public administration information (subject to the reasonable suspicion threshold in s 5(4)). The Act creates immunities and protections for informants but also imposes consequences for false disclosures (s 5, s 10).
Public officers and public sector employees. The Act draws a distinction between public officers and other persons. A public officer who makes an appropriate disclosure of public administration information is protected (s 5(1)(b), s 5(4)). The definitions cross‑refer to the Independent Commission Against Corruption Act 2012 and the Public Sector Act 2009 for the meaning of public officer, public administration, public sector agency and public sector employee (s 4). Principal officers of public sector agencies and councils bear statutory duties to designate responsible officers, publish procedures and make those procedures available to staff and the public (s 12). Responsible officers have statutory functions to receive and deal with disclosures and advise the principal officer (s 13).
Public sector agencies and councils. Agencies are required to have at least one responsible officer, to make contact details available to staff, and to maintain accessible procedures that include obligations to protect informants and risk management steps to address detrimental action against informants and persons against whom allegations are made (s 12(1)-(5)). The Act exempts very small agencies (consisting only of a single person) and agencies or councils granted written exemption by the Commission (s 12(6)).
Persons who receive disclosures. The statutory category of relevant authority in s 5(5) identifies who can lawfully receive disclosures and thereby trigger immunity and the duties in s 7. Relevant authorities include responsible officers, persons designated in guidelines as responsible for supervision, Commissioner for Public Sector Employment, the Ombudsman, council officers for local matters, the Environment Protection Authority, the Auditor‑General, police, the Judicial Conduct Commissioner, presiding officers for members of Parliament, Ministers, OPI, and other prescribed persons (s 5(5)). A person who receives a disclosure becomes subject to duties to assess, act and notify (s 7).
Journalists and members of Parliament. The Act allows for limited disclosure to a journalist or a member of Parliament other than a Minister, but only if strict preconditions are met: the person must already have made an appropriate disclosure to a relevant authority, have disclosed their identity to that authority, satisfy notification timeframes (30 days for one route, 90 days for another with possible extensions), and believe on reasonable grounds that the information is true (s 6).
Independent Commission Against Corruption, OPI and the Commission. The Act relies on institutional actors: the Commission (the Independent Commission Against Corruption) may publish guidelines and the OPI is a recipient of reporting about disclosures and outcomes (s 4, s 7(1)(c), s 14). The Commissioner occupies roles in amendments and discretion referenced in the legislative history. Regulations may permit matters to be determined at the discretion of the Commissioner (s 16(2)(c)).
Third parties and alleged persons. People who are the subject of allegations in disclosures are affected indirectly by the Act. Principal officers’ procedures must include risk management steps to minimise detriment to people against whom allegations are made (s 12(5)(a)(ii)(B)). Confidentiality obligations are subject to necessary disclosure for proper investigation (s 8(1)(a)).
Prosecutors and enforcement agencies. Specific enforcement limits apply to criminal prosecutions. For example, proceedings for the offence under s 9(5) (a person who personally commits an act of victimisation) may only be commenced by a police officer or a person approved by either the Commissioner of Police or the Director of Public Prosecutions (s 9(6)). Regulations may prescribe fines up to $5,000 and delegate decision-making to the Commissioner (s 16).
Members of the public. The Act requires procedures to be made available free of charge on the Internet and at specified premises for inspection by members of the public, and requires publication of guidelines by the Commission (s 12(5)(b), s 14(2)). Thus, anyone interested in the procedural framework can access the materials that agencies must maintain.
In short, the Act’s obligations and protections stratify by role: who discloses (private person v public officer), who receives the disclosure (list of relevant authorities), and who manages internal compliance (principal officers, responsible officers). The definitions in s 4 and the list in s 5(5) are the primary texts that determine which individuals and bodies are in each category.
