Information for principal officers

Mandatory notifications of public sector corruption will be introduced in December 2016. This obligation is set out in section 57 of the Independent Broad-based Anti-corruption Commission Act 2011 (the Act).

As the head of your department, agency or council (the ‘relevant principal officer’), you will be obligated to notify IBAC when you have reasonable grounds to suspect corruption is occurring or has occurred in your workplace.

What you must notify IBAC about

You must notify IBAC of all suspected corrupt conduct. There is no legislative obligation for relevant principal officers to search out corrupt conduct, only report it when suspected. 

Corrupt conduct is defined in section 4 of the Act

To be considered corrupt conduct, the conduct must also constitute an indictable offence against any Act, or the common law offence of attempt to pervert the course of justice, bribery of a public official, perverting the course of justice and misconduct in public office. 

You must have reasonable grounds to suspect the corrupt conduct is occurring or has occurred before notifying IBAC. This means making an assessment of whether there is a real possibility that corrupt conduct is, or may be, involved.

What happens after a notification is made

IBAC will acknowledge all notifications in writing. Relevant principal officers will be notified in writing of the results of IBAC’s assessment.  The notice will set out whether IBAC will dismiss, make preliminary inquiries, investigate or refer the notification to another person or body or back to the relevant principal officer, and any further steps that need to be taken. 

Relevant principal officers should contact IBAC if urgent action is required before or during the assessment.
