Victoria has four major integrity institutions sitting above its public sector, each with distinct but sometimes overlapping powers — and understanding which one handles what is essential for anyone considering blowing the whistle, lodging a complaint, or simply trying to follow a major public-interest investigation. This guide maps the architecture, explains how complaints route between bodies, and clarifies where the Public Interest Disclosures Act fits into all of it.
The four pillars: a quick taxonomy #
Think of Victoria’s integrity framework as a diamond rather than a pyramid. At the centre sits the concept of accountability; each institution approaches it from a different angle.
- Independent Broad-based Anti-corruption Commission (IBAC) — the corruption and serious-misconduct investigator. It can compel witnesses, conduct hearings (including in private), and refer matters for prosecution or disciplinary action.
- Victorian Inspectorate (VI) — the watchdog that watches IBAC and other bodies with coercive powers. It reviews how those institutions use their compulsory examination powers and investigates complaints about them.
- Victorian Ombudsman — the maladministration investigator. It handles complaints about administrative decisions by Victorian public bodies, including councils and most state agencies, and can investigate systemic issues on its own motion.
- Victorian Auditor-General’s Office (VAGO) — the financial and performance auditor. It does not investigate individual complaints; instead it conducts systemic audits of how public money is spent and whether programs deliver what they promise.
IBAC: the corruption and serious misconduct arm #
IBAC was established under the Independent Broad-based Anti-corruption Commission Act 2011 (Vic) and began operations in 2013. Its jurisdiction covers all Victorian public sector employees — including Victoria Police officers, parliamentarians, council staff, judicial officers (on a limited basis), and contractors acting on behalf of public bodies.
IBAC can investigate two broad categories: corrupt conduct (defined under the Act to include bribery, abuse of office, and conduct that adversely affects the honest exercise of public functions) and police personnel conduct (serious misconduct by Victoria Police members). It has coercive powers unavailable to the Ombudsman, including the ability to hold compulsory examinations — closed or public — and to require the production of documents. Public hearings, such as those examining integrity issues in the construction sector or local government procurement, are perhaps IBAC’s most visible tool, and they carry significant reputational weight.
Importantly, IBAC operates a threshold for investigation. Not every complaint meets the bar. The commission publishes guidance explaining that it prioritises matters involving serious or systemic corrupt conduct; lower-level misconduct is typically referred elsewhere — most often to the relevant agency’s own integrity unit, or to the Ombudsman.
The Victorian Inspectorate: watching the watchers #
The Victorian Inspectorate occupies a unique and sometimes misunderstood role. It does not investigate corruption or maladministration in the broader public sector. Its jurisdiction is deliberately narrow: it oversees bodies that themselves have coercive powers, chiefly IBAC, the Victorian Ombudsman, the Chief Examiner (who examines witnesses in major crime inquiries), and the Office of the Special Investigator.
If a person believes IBAC used its compulsory examination powers improperly — for instance, by examining a witness beyond the scope of a legitimate investigation — the Victorian Inspectorate is the correct body to receive that complaint. The VI can also inspect IBAC’s handling of protected disclosures (see below) and assess whether IBAC is complying with its own legislative obligations. This creates a genuine accountability loop: the body with the most investigative power is itself subject to independent oversight.
The Victorian Ombudsman: maladministration and systemic review #
The Ombudsman’s office, established under the Ombudsman Act 1973 (Vic), handles complaints about administrative actions taken by Victorian public bodies — meaning almost any decision or conduct by a state agency, council, university, or statutory authority that a person believes was wrong, unreasonable, or procedurally unfair.
Unlike IBAC, the Ombudsman does not need a threshold of corrupt conduct to investigate. A council unreasonably refusing to process a planning application, a government department losing a welfare applicant’s file, a prison failing to provide adequate medical care — these are all within scope. The Ombudsman can also launch own-motion investigations into systemic failures, and has done so on issues ranging from disability services to the handling of prisoner grievances.
Where a complaint lodged with the Ombudsman appears to disclose corrupt conduct rather than mere maladministration, the Ombudsman has an obligation under the IBAC Act to notify IBAC. The two bodies have a memorandum of understanding governing referrals, and in practice a complaint may begin with the Ombudsman and be escalated — or referred back — depending on the seriousness of the alleged conduct. In major infrastructure contexts, such as complaints about Big Build procurement decisions, the line between maladministration (Ombudsman territory) and corrupt conduct (IBAC territory) can be genuinely contested.
VAGO: auditing money and performance, not individuals #
The Victorian Auditor-General’s Office operates under the Audit Act 1994 (Vic) and is constitutionally independent of the executive government. Its work falls into two streams: financial audits (verifying that agencies’ financial statements are accurate) and performance audits (examining whether programs achieved their stated objectives efficiently and effectively).
VAGO does not investigate individual complaints and has no power to compel witnesses in the way IBAC can. Its strength lies in system-level scrutiny. A VAGO performance audit of a major infrastructure project — examining whether contract governance met probity standards, whether value-for-money was achieved, whether relevant risks were disclosed to parliament — can lay the evidentiary groundwork that later prompts an IBAC or Ombudsman investigation. The Auditor-General reports to parliament, not to the government of the day, which is a structural safeguard worth noting.
The Public Interest Disclosures Act: how whistleblowers plug in #
The Public Interest Disclosures Act 2012 (Vic) — commonly called the PID Act — is not an investigative body but a disclosure pathway and protection regime that threads through all four institutions. Under the Act, a person can make a protected disclosure about improper conduct by a public officer or body to a disclosure co-ordinator within their agency, or directly to IBAC.
Once a disclosure is received and assessed, it may be:
- Investigated by IBAC directly (if it meets the corrupt conduct or police misconduct threshold);
- Referred by IBAC to the Ombudsman (if it is more properly characterised as maladministration);
- Referred back to the relevant agency’s own investigation unit under IBAC oversight;
- Referred to another integrity body such as the Victorian Inspectorate if the conduct relates to a body within VI’s jurisdiction.
Critically, the Act provides legal protections for disclosers: a person who makes a protected disclosure cannot be subject to detrimental action — sacking, demotion, harassment — as a result. The Victorian Inspectorate monitors compliance with these protections across all bodies that receive disclosures. A discloser who believes they have suffered reprisal can complain to the Victorian Inspectorate, which can investigate and recommend action.
Where complaints go wrong: the referral trap #
One of the most common frustrations reported by complainants — and something our newsroom has heard repeatedly from sources navigating major infrastructure disputes — is the experience of being referred between bodies without resolution. A complaint lodged with IBAC may be assessed as falling below threshold and referred to the Ombudsman; the Ombudsman may determine the conduct is more properly characterised as corrupt and notify IBAC; the agency’s own integrity unit may be tasked with investigating conduct by its own senior managers.
This is not simply bureaucratic dysfunction. The framework is deliberately structured so that the most coercive and resource-intensive body — IBAC — focuses on serious and systemic corruption rather than routine grievances. The challenge for complainants is understanding which door to knock on first, and the PID Act’s disclosure co-ordinator system is intended to ease that burden. In practice, legal advice before making a disclosure is strongly recommended, particularly where a complainant fears reprisal or where the conduct involves senior officials.
Keeping track: resources and support #
Anyone considering making a disclosure or lodging a complaint with one of these bodies can find published guidance on each institution’s website. IBAC’s complaint assessment guidelines, the Ombudsman’s complaint form, and the Victorian Inspectorate’s protected disclosure guidance are all publicly available. For those uncertain which body applies, IBAC’s intake team can assist with initial triage.
