There are two ways to tell IBAC about public sector corruption or police misconduct.

Make a complaint

Make a complaint

A formal way to notify IBAC of public sector corruption or police misconduct. A complaint should detail the alleged conduct, including who was involved, what occurred, where and when, and may include supporting documentation.

  • Complaints can be anonymous
  • Every complaint received is assessed to determine if it is a protected disclosure
  • Complaints may be investigated by IBAC, referred to another agency or dismissed. Learn more about possible complaint outcomes.
  • If you leave contact details, IBAC may contact you seeking further information. IBAC will inform you of the outcome of your complaint, normally within 60 days.
