Victoria Police is far larger than the uniformed officers you see at your local station — behind the blue line sits a layered architecture of specialist squads, each tasked with a distinct category of serious crime. Understanding how those units are structured, who they answer to, and how a case travels from a patrol car to a specialist detective’s desk helps the public make sense of what is often a complex and opaque system.
The Hierarchy: Where Specialist Squads Sit #
Victoria Police’s specialist detective units sit predominantly within Crime Command, one of the organisation’s four core commands. Crime Command is headed by a Deputy Commissioner and oversees the bulk of serious and organised crime investigation across the state. Beneath that tier, most specialist squads operate under the Specialist Operations division, though some units — particularly those with a regional focus — are embedded within the relevant area command and liaise upward when cases escalate.
The day-to-day work of local criminal investigation falls to Criminal Investigation Units (CIUs) attached to divisional or regional stations. When an offence exceeds the capacity, resources, or legal complexity of a CIU — or falls within a category of crime that requires dedicated expertise — it is referred upward to the relevant specialist squad. That referral can come from a local detective, a prosecutor, an intelligence analyst, or, increasingly, from data-matching systems that flag patterns across multiple incidents.
Homicide Squad #
The Homicide Squad is perhaps Victoria’s most publicly recognised specialist unit. It investigates all homicides in the state — including murder, manslaughter, and cases where a death is suspicious or unexplained — as well as serious assaults and some missing-persons cases where foul play is suspected. The squad is based in Melbourne but deploys investigators state-wide when required.
Cases typically come to the Homicide Squad via two routes: a local CIU identifies a death as suspicious and calls in homicide detectives to take over the primary investigation, or an initial patrol response escalates rapidly enough that the squad is called to the scene from the outset. The squad works closely with Victoria’s coronial system, and detectives frequently give evidence at inquest hearings before the Coroners Court of Victoria.
It is worth noting that the Homicide Squad does not investigate all deaths — the State Coroner has a separate and independent jurisdiction over reportable deaths, and the two agencies operate in parallel rather than under a chain-of-command relationship.
Sexual Offences and Child Abuse Investigation Teams (SOCIT) #
Sexual offences and child abuse are handled by a network of Sexual Offences and Child Abuse Investigation Teams, commonly known by the acronym SOCIT. Unlike some other specialist squads that are centralised in a single location, SOCIT operates from nodes across metropolitan Melbourne and regional Victoria, reflecting the principle that victims of sexual offences should not have to travel significant distances to be interviewed.
SOCIT detectives are trained in trauma-informed interviewing and work alongside specialists from the Centre Against Sexual Assault (CASA) network. Cases come to SOCIT either through a direct report to police or via a referral from another agency — a school, a hospital, a child protection worker, or the Department of Families, Fairness and Housing. Where a matter involves a child victim or a child accused, strict legal protections apply and cases may be heard in the Children’s Court rather than the Magistrates’ or County Court.
Armed Crime Squad #
The Armed Crime Squad investigates offences involving the use or threatened use of firearms and other weapons in the commission of serious crimes — armed robbery, aggravated carjacking, and targeted shootings that fall short of the homicide threshold. The squad also manages investigations where organised groups are suspected to be behind a pattern of armed offending.
Cases reach the Armed Crime Squad when local investigators determine that the level of violence, the apparent organisation behind the offending, or the need for covert investigative techniques — surveillance, controlled operations, or proceeds-of-crime applications — exceeds what a divisional CIU can manage. The squad coordinates closely with the Ballistics and Forensic Firearms unit within the Victoria Police Forensic Services Centre when trace evidence from firearms is a key evidentiary issue.
Arson and Explosives Squad #
The Arson and Explosives Squad investigates deliberate fires, explosive devices, and suspicious fire deaths. Victoria’s landscape — and the catastrophic potential of bushfire arson — gives this squad a significance that extends well beyond metropolitan crime. The squad deploys fire-scene investigators who work alongside Fire Rescue Victoria and the Country Fire Authority to determine whether an ignition point was accidental, natural, or deliberately set.
A key function of the squad is intelligence-led analysis: serial arsonists often escalate over time, and analysts within the unit track patterns of ignition across geographic areas and time periods. Referrals come from fire agencies, insurers (through formal information-sharing arrangements), local police, and occasionally the public via Crime Stoppers.
Drug Investigation Division #
The Drug Investigation Division (DID) sits within Crime Command and is responsible for the investigation of serious drug trafficking and manufacture. It is distinct from the street-level drug enforcement carried out by local CIUs and uniform members — the DID focuses on supply chains, large-scale importation, clandestine laboratory operations, and the financial infrastructure that sustains drug markets.
The DID works closely with the Australian Federal Police, the Australian Border Force, and the Australian Criminal Intelligence Commission (ACIC) on matters with a cross-jurisdictional or transnational dimension. Controlled delivery operations — where law enforcement monitors a drug shipment moving through the supply chain — require coordination across multiple agencies and are typically led or co-led by the DID when a Victorian nexus is identified.
Referrals to the DID often originate from intelligence rather than a complaint: information from informants, intercept material, or analytical work identifying a network rather than a single incident.
Anti-Gangs Squad and Organised Crime #
The Anti-Gangs Squad targets criminal networks and outlaw motorcycle gangs (OMCGs) operating in Victoria. Its remit overlaps with — and complements — the work of the Armed Crime Squad and the Drug Investigation Division, because organised criminal groups typically operate across all three domains simultaneously.
The squad carries out long-running proactive investigations rather than reactive single-incident responses. Intelligence collection, surveillance, and the use of covert human intelligence sources are central to its methodology. The Anti-Gangs Squad also administers Victoria’s firearms prohibition order regime in respect of high-risk individuals, and liaises with interstate counterparts through the National Anti-Gangs Squad (NAGS), a multi-agency taskforce with an AFP umbrella.
Cases rarely begin with the Anti-Gangs Squad receiving a complaint — they more often evolve out of intelligence packages that identify an individual or group as the suspected organiser of lower-level offending that has already come to the attention of other units.
How Cases Move Through the System #
The journey from a triple-zero call or a formal complaint to a specialist squad investigation is rarely linear. Victoria Police uses an intelligence-led policing model, which means analysts at both local and command level continuously assess whether an emerging pattern of offending warrants escalation. A cluster of residential burglaries might sit with a local CIU indefinitely; if those burglaries are linked to a known criminal network moving drugs, the Drug Investigation Division or Anti-Gangs Squad may take an interest.
The Victoria Police Intelligence Fusion Centre plays a coordination role, aggregating information from multiple sources and distributing intelligence products to relevant squads. Where an investigation requires the use of assumed identities, surveillance devices, or other controlled operations under the Major Crime (Investigative Powers) Act 2004 (Vic), senior officers within the relevant squad must seek authorisation from designated approving officers, and in some cases, from the Supreme Court of Victoria.
The Office of Public Prosecutions (OPP) becomes involved once charges are laid, and specialist prosecutors — particularly in matters involving sexual offences, homicide, or serious organised crime — work alongside squad detectives to prepare briefs for the County Court or the Supreme Court.
Accountability and Oversight #
Specialist squads are not exempt from external scrutiny. The Independent Broad-based Anti-corruption Commission (IBAC) has jurisdiction to investigate serious misconduct by Victoria Police members, including those in specialist units. The Victorian Inspectorate oversees IBAC itself. Complaints about police conduct can also be made directly to IBAC or to the Victoria Police Professional Standards Command.
Members of the public who have information about serious crime — including information relevant to any of the squads described above — are encouraged to contact Crime Stoppers on 1800 333 000 or report online at crimestoppersvic.com.au. Reports can be made anonymously.
