IBAC determines if there's been corruption or police misconduct, at the end of an investigation.

If we find evidence of corruption or police misconduct

We may:

During our investigations, we:

  • use investigative techniques to gather information

  • hold public or private examinations (hearings) to question witnesses.

Why we investigate

Our powers to investigate allegations of public sector corruption and police misconduct allow us to:

  • compel people to produce documents and items
  • enter and search premises
  • seize documents and objects
  • use surveillance devices
  • intercept telecommunications
  • hold private and public examinations
  • require people to give evidence at an examination.

These powers are limited during a preliminary inquiry

We can investigate and take complaints about police misconduct or corruption involving the following public bodies and officers.

IBAC prioritises investigations into allegations of serious or systemic public sector corruption and police misconduct.

For legal and operational reasons, most of our investigations are private and not commented about, or reported on publicly, until they're finished.

IBAC investigates complaints about:

  • corruption in Victoria’s public sector 
  • police misconduct. 

We prioritise serious or systemic corruption.

Wednesday 14 Dec 2022 Survey results show perceptions of public sector corruption and police misconduct are on the rise
Results from the Independent Broad-based Anti-corruption Commission's (IBAC) most recent 'perceptions of corruption' surveys reveal an increase in the perception that public sector corruption and police misconduct are a problem in Victoria when compared to the survey results in 2019 and 2016. In addition, procurement and recruitment are seen as high-risk areas for corruption and misconduct, with favouritism, bullying and harassment perceived as the most prevalent breaches of professional conduct in the public sector and Victoria Police.

Everyone can help prevent public sector corruption and make sure public funds are spent as intended - maintaining Victoria's schools, hospitals, roads and other vital public services and projects.
