Report corruption or misconduct

There are two main 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.
  • Complaints received are assessed to determine if they are public interest disclosures.
  • 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. 


Provide information

You can give IBAC information about public sector corruption or police misconduct without making a formal complaint. Information you provide may assist with investigations or corruption prevention initiatives. The ’Provide information’ form is for people who do not want to make a complaint or public interest disclosure, but want to share information with IBAC.

  • You can provide information anonymously.
  • Provide as little or as much information as you have.
  • If you leave contact details, IBAC may contact you about your information.
  • IBAC considers information reports to determine if they are public interest disclosures.
  • No feedback will be provided on the progress or outcomes of the information you’ve provided.

If you need help or want to speak with us in person, please call 1300 735 135.

Complaints must be provided in writing and are not accepted over the phone. Use the online complaint form or other reporting methods.

Please note: IBAC is not a complaints resolution body.

Our service charter explains what to expect when you make a complaint to IBAC.

Under the Independent Broad-based Anti-corruption Commission Act 2011 a person may make a complaint to IBAC about conduct they believe may be corrupt conduct. IBAC must dismiss, investigate or refer complaints received.
