We safeguard our clients’ interests in whistleblower matters by providing fair, practical and sound advice

Whistleblower complaints are often complex, sensitive and high-impact. They can involve serious allegations, tight timelines and overlapping legal duties, from protecting identities to managing regulator expectations.

At Mallesons, we help organisations respond to whistleblowing complaints lawfully and fairly. Our team brings deep experience in corporate governance, investigations and dispute resolution, guiding clients through each stage of the process.

Proven success in action

Investigating subcontractor misconduct linked to phoenix activity

We advised a national client in response to whistleblower concerns about illegal activity by third parties.  The allegations involved a network of related entities. We led a discreet internal investigation, including forensic document review, interviews, and stakeholder engagement. Our findings enabled the client to terminate high-risk relationships, implement tighter third-party controls, and engage with regulators on next steps – reducing legal exposure and safeguarding the integrity of their supply chain. 

Guiding a major financial institution through a high-profile whistleblower investigation

We advised a financial institution on a sensitive whistleblower complaint involving allegations against senior executives. We managed the full investigation – including forensic reviews, witness interviews and engagement with the whistleblower – and provided clear, actionable recommendations to the board. Our work helped the client uphold governance standards while preserving procedural fairness and confidentiality.

Whistleblower report of alleged modern slavery

Our client received a whistleblower report of alleged modern slavery in its Australian supply chain. The allegations were highly sensitive and required a swift response that could penetrate the supply chain. Mallesons conducted an expedited investigation into the allegations and advised the client on its criminal reporting obligations in connection with the report.
