IBAC investigates complaints about:

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

We prioritise serious or systemic corruption. 

Preliminary inquiries

Sometimes we conduct a preliminary inquiry to decide whether to investigate. As part of this, we can request information, documents or other relevant items. 

Lots of complaints aren't investigated

This is because they:

  • don’t involve corrupt conduct or police misconduct 
  • aren’t about who we investigate
  • lack substance or credibility, or are frivolous or vexatious
  • have already been dealt with by us or another agency.

We don't need a complaint to start an investigation

'Own motion' investigations can be initiated by our Commissioner if a matter within IBAC's jurisdiction comes to our attention another way.
