page 17 mentions a whistleblower policy and Whistle Blower Investigation Officer

p. 16 focal point: "There are various ways in which our employees can raise concerns regarding conduct occurring at AGL or in relation to AGL. Under the AGL Code of Conduct, employees and contractors are encouraged to report concerns relating to observed behaviours or where there is a reasonable suspicion of a breach of AGL’s Code of Conduct, to their immediate leader. In circumstances where the report concerns their leader or if the person is not satisfied with how their leader is treating the matter, the matter can be reported to their business partner in People & Culture or to the Executive Team member responsible for their business unit. Suppliers are required to notify AGL of any actual or suspected breach of theSupplier Code of Conduct by the supplier or by their supply chain."

p. 16 hotline, wb protection: "In addition to these mechanisms, AGL's current and past employees, officers, contractors, suppliers (including employees of suppliers), and their associates are able to report and express any concerns relating to our activities and suspected violations of our policies, Values and/or legal requirements via our Whistleblower Protection Policy. AGL has two channels through which grievances or concerns about matters covered by the AGL Whistleblower Policy can be raised. Individuals are able to report the matter internally to any of our eligible recipients (which include AGL’s Executive Team) or make a report anonymously via our whistleblowing hotline.

Given that they mention a whistleblower protection policy in addition to the whistleblower policy, it seems clear that whistleblowers are protected
