Criminal activity in Victoria, Australia is combated by the Victoria Police and the Victorian court system, while statistics about crime are managed by the Crime Statistics Agency. Modern Australian states and cities, including Victoria, have some of the lowest crime rates recorded globally with Australia ranked the 13th safest nation and Melbourne ranked the 5th safest city globally. As of September 2018 the CBD of Melbourne had the highest rate of overall criminal incidents in the state (15,949.9), followed by Latrobe (12,896.1) and Yarra (11,119.2). Rural areas have comparatively high crime rates, with towns such as Mildura (9,222.0) and Greater Shepparton (9,111.8) having some of the highest crime rates in the state.^{[2][3][4][5][6]}

Victoria has had a comparatively low crime rate throughout its history, particularly in relation to the homicide rate which has been and remains notably lower than that of comparable nations. During the colonial period (1851–1901) drunkenness was the most widely reported crime, and in 1907 about 40% of all convictions nationwide were for drunkenness. Fraud was also common in the Victorian colony due to a shortage of currency and the common use of promissory notes. Victorian crime data and reporting prior to Australian Federation is generally seen as unreliable or inconsistent, with the exception of homicide rates.^[7]

Statistics released by the Crime Statistics Agency in September 2018 showed a 7.8% drop in the overall crime rate. The statistics showed the criminal incident rate fell to 5,922 cases per 100,000 people in the previous year, continuing a trend of reduction in the overall number of criminal incidents from the previous year, with significant falls in theft, burglaries and drug dealing.^[6]

In the year ending September 2020, the statistics were skewed by the introduction of six new public safety offences relating to the COVID-19 pandemic in Australia.^[8] Total offences numbered 551,710, with 32,713 of these were breaches of Chief Health Officer Directions. The total offences occurred at a rate of 8,227 per 100,000 people, up 4.4% on the previous year. While there have been some dips along the way, the rate of recorded offences have increased year on year since 2011, when the figure was 6,937.7 offences per 100,000 people.^[9]

Though often not recorded as crimes at the time, numerous crimes were perpetrated against Aboriginal Victorians throughout the colonial period. Among the most heinous of these crimes were massacres. The following list tallies the better documented massacres of Aboriginal Victorians. The information provided below is based on ongoing research 'Violence on the Australian Colonial Frontier, 1788–1960' undertaken by the Australian Research Council.^[11][12]

• 1833–34 Convincing Ground massacre – Between 60 and 200 Gunditjmara men, women and children were reported to have been murdered. Committed on the shore near Portland, Victoria, it was one of the largest recorded massacres in Victoria.^[13]
• 1839 Campaspe Plains massacre – Between 40–50 Taungurung and Dja Dja Wurrung people were murdered by a group of settlers, led by Charles Hutton at Campaspe Creek, Central Victoria.^[14]

Convicts were never directly transported to Victoria, however at least 300 convicts arrived in Sorrento in 1803 as part of Colonel David Collin's short-lived, first attempt at British settlement in Victoria, in 1804. This first group of convicts also included the famous escaped convict William Buckley. Over the following decades small numbers of convicts were sent from Tasmania and New South Wales to carry out government work, surveying and labour.^[20]

From the 28th of November till the 3 December 1854 the Eureka Stockade took place in what is now the suburb of Eureka, Ballarat. Gold prospectors staged an uprising against the colonial government which lead to an armed conflict; 22 miners and 6 soldiers were killed. The event is significant in Australian history, particularly in regards to the development of democracy.^[21] In the colony's capital of Melbourne there was enormous support from the public for the captured Eureka rebels, this support was one of the factors that lead to the creation of the Electoral Act 1856, leading to colonists being granted male suffrage, on condition of owning property, in the lower house in the Victorian parliament.^[22][23]

In January 2012 widespread sexual and other abuse of children by personnel in religious organisations was exposed by the Protecting Victoria's Vulnerable Children Inquiry.^[24] The inquiry recommended that a formal investigation should be conducted into the processes by which religious organisations respond to the criminal abuse of children within their organisation.^[25] In response to the inquires recommendations, the Chief Commissioner of Victoria Police, Ken Lay argued that the Roman Catholic Church's attempts to hinder investigations be criminalised.^[26]

Later in 2012, Prime Minister Julia Gillard, announced the creation of a Royal Commission into sex abuse within the Catholic Church.^[27] An estimated 60,000 Australians were abused in churches, schools, sporting clubs and health services, with the majority of the abuse occurring in New South Wales and Victoria.^[28] Institutions that failed to respond appropriately or effectively to widespread child sex abuse in Victoria include: the Anglican Church, the Catholic Church, The Salvation Army, the Jehovah’s Witnesses, Australian Christian Churches, Australian Pentecostal churches, Yeshivah Melbourne and the Christian Brothers among others.^[29] The Royal Commission into Institutional Responses to Child Sexual Abuse found that one school run by the Christian Brothers, St Alipius boys school in Ballarat East, was staffed almost entirely by paedophiles.^[30]

The Royal Commission found many of the worst incidents in Victoria occurred in the Roman Catholic Diocese of Ballarat. One of Australia's most infamous paedophiles, former priest Gerald Ridsdale was based in Ballarat and protected by church hierarchy, who shifted Ridsdale from parish to parish, between 1961 and 1988, in order to cover-up Ridsdales crimes. Ridsdale was convicted of 138 sex offences against children, he sexually abused as many as 50 children.^[31]

On 11 December 2018, Ballarat born former Cardinal George Pell, was convicted on five counts of child sexual abuse of two boys in the 1990s.^[32][33][34] Pell was eventually acquitted by the High Court of Australia.

Despite Melbourne's CBD having the state's highest crime rate (15,949.9)^[6] the city is considered one of the safest in the world,^[5] with Melbourne being ranked the 5th safest city globally. The notably low crime rate is one of the factors that led to Melbourne being named the world's most liveable city by The Economist for seven years in a row up until 2017. The recorded homicide rate of Melbourne was 2.2 per 100,000 in 2018.^[35][36]

• Apex – Apex, otherwise known as the Apex Gang, was a term used to describe an informal group of young male criminals accused of being involved in street crime in and around Melbourne in 2015–18. The name was frequently invoked during the "African Gang Crisis" debate in the media in 2018. The nature and existence of the "gang" was uncertain and many claims regarding the group have been described as exaggerated by police, politicians, journalists and others.^[47] Home Affairs Minister Peter Dutton claimed that Victorians were scared to go to restaurants at night because of "African gang" violence. Victoria Police stated that the group included a diverse range of young people from different ethnic backgrounds, the majority of them born in Australia.^[48][49]

The Mallee and Mildura in particular have long been associated with the Calabrian Mafia, with claims made by police in 1966 that annual organised crime meetings were held in Mildura to co-ordinate nationwide criminal activities.^[50] In a 1960s National Anti-Mafia Directorate report by John T. Cusack (United States' Bureau of Narcotics) and Dr Ugo Macera (assistant commissioner of police in Calabria) claims were made that the "ancient Calabrian Secret Criminal Society known as the L'Onorata Societa" and the "`Ndrangheta" were operating "throughout the State, with large segments in the fruit growing and farming areas of Mildura and Shepparton" adding that "There are reports the Society has existed in Victoria since 1930". They have reportedly been involved in revenge killings, cannabis production and weapons purchases.^[51]

During the 1980s the Mildura Mafia emerged as a major crime group that dominated marijuana production in Australia and ran an Australia-wide money-laundering network.^[52] Several notable mafia murders have been linked to the region including the suspected mafia hit on 43-year-old Marco Medici in 1983, police believe the murder may be connected to the assassination of anti-drug crusader Donald MacKay at Griffith in 1977.^[53] The 1984 murders of Melbourne gangsters Rocco Medici and Giuseppe Furina are also connected to Mildura through the Medici family. In 1982, 42-year-old Mildura greengrocer Dominic Marafiote and his parents were murdered after Marafiote gave South Australian police the names of Calabrian mafia bosses in South Australia, Victoria and New South Wales.^[54] In 2016 Mildura residents Nicola Ciconte, Vincenzo Medici and Michael Calleja were convicted and sentenced in Italy for their role in a plot to smuggle up to 500 kilograms of cocaine into Australia.^[55][56]

Beginning in 2010, Victoria has seen a significant increase in the use of Methamphetamine, commonly referred to as ice. While relatively few Australians report using ice compared to other drugs, rates of methamphetamine use are significantly higher among rural and remote areas of Victoria compared to major cities. Rural methamphetamine use rates are 2.5 times higher than those in metropolitan areas. Prior to 2010 rates of use of illicit drugs in rural areas were significantly lower than those in the cities.^[57]

In 2014, A Comancheros Motorcycle Club member and former Australian Defence Force (ADF) sniper, Joshua Faulkhead, was arrested after being caught transporting large quantities of methamphetamine, cocaine and ecstasy between Sydney and Mildura.

The drugs seized were reported to be worth more than $15,000. $20,000 in cash and weapons were also seized.^[59] Later that same year, Stephen Gillard and Geoffrey Hitchen from South Penrith, were arrested for possession of $300,000 worth of methamphetamines in scrubland off the Mallee Highway at Tutye, west of Ouyen. Local farmers uncovered plastic fruit juice bottles containing the drugs after noticing the men behaving strangely the previous day.^[60]

The 72-year-old pilot, a 52-year-old man, from Zetland in Sydney's east and a 58-year-old Melbourne man were charged with conspiracy to import a commercial quantity of border controlled drugs and money laundering offences. The crystal methamphetamine was reported to be worth $255 million. That arrests were connected to $2.4 million which was found in Mildura, in a prime mover that was driven from Adelaide in April.^[61]
