Whistleblower Protection in the South Australian Public Sector

South Australia's Public Interest Disclosure Act 2018 protects public officers, and for environmental and health risks any person, who report specified wrongdoing to the right recipient, but its reprisal and confidentiality offences carry a flat penalty of $20,000 or imprisonment for two years, not a penalty unit multiplier. The Act was last amended on 7 October 2021 and remains the current version.

Who the Act Covers and What Counts as Public Interest Information

The Public Interest Disclosure Act 2018 (SA) does not gate protection by job title the way several other states do. It turns instead on the type of information disclosed. Section 4 defines public interest information in two categories. The first, environmental and health information, covers a potential issue of substantial risk to the environment or to public health or safety, and section 5(1)(a) lets any person disclose it, not only a public officer. The second, public administration information, covers a potential issue of corruption, misconduct or maladministration in public administration, and section 5(1)(b) restricts that category to a public officer as defined in section 5(4). The Act cross references the Independent Commission Against Corruption Act 2012 for what counts as corruption and the Ombudsman Act 1972 for misconduct and maladministration, rather than defining those terms itself.

Where to Report It: The Relevant Authority Menu

South Australia does not funnel disclosures through one single office. Section 5(5) lists a menu keyed to subject matter: the discloser's own management or, for public sector matters, the agency's designated responsible officer under sections 12 and 13; the Ombudsman for agencies covered by the Ombudsman Act 1972; a council officer for local government matters; the Environment Protection Authority for environmental risk; the Auditor General for irregular use of public money; police for a suspected offence; the Judicial Conduct Commissioner for judicial officers; the relevant Presiding Officer for members of Parliament; a Minister of the Crown; and the Office for Public Integrity, which functions as the default recipient for corruption, misconduct and maladministration matters generically. Every public sector agency and council must designate at least one responsible officer, publish their contact details, and maintain a free, public disclosure procedures document under sections 12(4) and 12(5), unless it is a single-person agency or holds a written exemption from the Independent Commission Against Corruption.

External disclosure to a journalist or a member of Parliament who is not a Minister is narrower than that list suggests. Section 6 allows it only where the discloser already made an appropriate disclosure under section 5, identified themselves to that recipient, received no acknowledgment within 30 days or no outcome notification within 90 days, and still believes on reasonable grounds that the information is true. No emergency or imminent danger fast track comparable to the Commonwealth Public Interest Disclosure Act's provision for urgent risks appears in this Act's operative text.

Protections and the Reprisal Offence

A person who makes an appropriate disclosure is immune from liability under section 5(1) and 5(2), despite any duty of secrecy or confidentiality that would otherwise apply, and the recipient has a statutory duty under section 7 to assess the disclosure, act on it or record a reason for not doing so, notify the informant, and report to the Office for Public Integrity. Reprisal against a discloser is called victimisation. Section 9(1) creates a civil wrong for causing detriment because a person made or intends to make an appropriate disclosure, and section 9(5) makes it a criminal offence for a person who personally commits an act of victimisation, with a maximum penalty of $20,000 or imprisonment for two years. That figure is a flat dollar amount rather than a penalty unit multiplier; South Australia does not use penalty units for this Act at all. Section 9(6) requires a police officer, or a person approved by the Commissioner of Police or the Director of Public Prosecutions, to bring a prosecution. A victim can pursue a tort damages claim or an Equal Opportunity Act 1984 complaint under section 9(2), but not both. Two related offences, making a false or misleading disclosure under section 10 and preventing or hindering a disclosure under section 11, carry the same $20,000 or two year maximum; a discloser convicted of knowingly making a false disclosure loses the Act's protection entirely under section 10(2).

Confidentiality of Your Identity

Section 8 makes it an offence for anyone to whom a disclosure is made or referred, or who otherwise learns of it, to knowingly divulge the informant's identity without consent, except so far as necessary for a proper investigation or under guidelines issued by the Independent Commission Against Corruption under section 14. The maximum penalty is the same as the reprisal offence, $20,000 or imprisonment for two years, again a flat figure rather than a penalty unit calculation.

How a Disclosure Is Assessed: The Office for Public Integrity and ICAC's Narrower Role

This is the point most likely to be misunderstood, so it deserves care. The Office for Public Integrity, established under Part 3 of the Independent Commission Against Corruption Act 2012, receives and assesses public complaints and reports of corruption, misconduct and maladministration, and refers them onward or takes no action. The Independent Commission Against Corruption itself has had a narrower jurisdiction since a 2021 reform: its own investigative functions are limited to corruption in public administration specifically. Section 7(1)(d) of that Act requires the Commission to report out, not investigate, any misconduct or maladministration it encounters while investigating corruption, and the assessment and referral mechanics in sections 18E to 18G send non-corruption matters to an inquiry agency, a defined term that includes the Ombudsman but not the Commission for that category. In practice, corruption sits with the Independent Commission Against Corruption; misconduct and maladministration sit with the Office for Public Integrity at intake and the Ombudsman for investigation.

If You Work for the Commonwealth or in the Private Sector

This article covers disclosures by South Australian public officers and, for environmental and health risks, any person, under the state's own Act. A person employed by the Commonwealth government reports under a different statute entirely, the Commonwealth Public Interest Disclosure Act, with its own oversight body and reprisal offence. A private sector employee's whistleblower protections come from a third, separate regime under the Corporations Act, not from either public interest disclosure framework.
