Whistleblower protections under the Corporations Act

In short

Part 9.4AAA of the Corporations Act 2001 (Cth), as expanded by the Treasury Laws Amendment (Enhancing Whistleblower Protections) Act 2019, provides strong legal protection for whistleblowers who disclose corporate misconduct. Every public and large proprietary company must have a compliant policy. This guide walks through 10 core obligations.

Who must comply

Coverage

Every public company, large proprietary company, and trustee of a registrable superannuation entity must have a whistleblower policy. The protections apply across all ASIC-regulated entities and extend to current and former officers, employees, contractors, suppliers and their relatives.

Legal basis

Corporations Act 2001 (Cth) Part 9.4AAA (ss 1317AA-1317AE) governs corporate whistleblower protections. Tax Administration Act 1953 (Cth) Part IVD covers tax-specific whistleblowing. ASIC Regulatory Guide 270 sets out compliant policy content.

10 obligations

The obligations

1

Maintain a compliant whistleblower policy

Public and large proprietary companies must have a written whistleblower policy covering the matters in RG 270 — protections, eligible recipients, confidentiality, investigation processes, and support available to whistleblowers.

Corporations Act 2001 (Cth) s 1317AI; ASIC RG 270
2

Identify the broad class of eligible whistleblowers

Eligible whistleblowers include current and former officers, employees, contractors, suppliers, associates, and relatives or dependants of any of those. The class is much wider than employees alone.

Corporations Act 2001 (Cth) s 1317AAA
3

Define eligible disclosable matters

Disclosures are protected if they concern misconduct, improper state of affairs, a breach of the law, or a danger to the public — about the entity or its officers or employees. Personal work-related grievances are generally not protected.

Corporations Act 2001 (Cth) s 1317AA
4

Identify eligible recipients

Disclosures are only protected if made to an eligible recipient — typically an officer, senior manager, auditor, actuary, ASIC, APRA, or a legal practitioner for legal advice purposes. The policy should list the internal recipients clearly.

Corporations Act 2001 (Cth) s 1317AAC
5

Maintain strict confidentiality

It is an offence to disclose the identity of a whistleblower (or information that could identify them) without consent, outside the permitted exceptions. Penalties for breach are significant.

Corporations Act 2001 (Cth) s 1317AAE
6

Protect whistleblowers from detriment

It is prohibited to cause or threaten detriment (dismissal, demotion, harassment, discrimination, harm to reputation or property) to a whistleblower because of a protected disclosure.

Corporations Act 2001 (Cth) s 1317AD
7

Provide immunity from certain liability

A whistleblower making a protected disclosure has immunity from civil, criminal, and administrative liability for making the disclosure, and from breach-of-contract actions.

Corporations Act 2001 (Cth) s 1317AB
8

Train officers and senior managers

Officers and senior managers — particularly those who may be eligible recipients — need training on the protections, the confidentiality regime, and the investigation process. RG 270 flags training as an expected policy element.

ASIC RG 270
9

Run a compliant investigation process

Investigations must be conducted fairly, confidentially, and by people independent of the matter. The whistleblower should be kept informed. The investigation process needs to be described in the policy.

ASIC RG 270 section D
10

Retain records and report concerns externally where required

Maintain records of disclosures and investigations. Where a disclosure relates to matters requiring external reporting (ASIC, APRA, AUSTRAC, police) ensure that chain is followed while preserving whistleblower confidentiality.

Corporations Act 2001 (Cth) Part 9.4AAA; ASIC RG 270
Penalties

What happens if you do not comply

Breach of confidentiality: up to $1.565 million (individual) or 3x benefit / 10% turnover (corporation). Detriment offences: criminal penalties up to 2 years imprisonment and $264,000 (individuals). The court can also order reinstatement, compensation, and exemplary damages.

Reporting requirements

No periodic regulator reporting, but serious or systemic whistleblower disclosures often trigger separate regulator notification obligations (ASIC, APRA, AUSTRAC, AFSA). Document retention for at least 7 years is expected practice.

Practical steps

What firms should do today

  • Publish the whistleblower policy on the intranet and in the employee handbook
  • Nominate at least two internal eligible recipients — ideally across different functions
  • Run annual training for all people managers on the confidentiality and detriment rules
  • Set up a confidential external reporting line (phone or platform) as an alternative to internal disclosure
  • Test the investigation playbook with a tabletop exercise at least annually
  • Separate whistleblower investigations from HR grievance processes — different playbooks apply
