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.
