The Hells Angels Motorcycle Club (HAMC), an international outlaw biker gang, has been involved in multiple crimes, alleged crimes, and violent incidents in Australia. The Hells Angels are legally classified as a criminal organisation in the Australian state of Queensland, and there have been attempts to classify them as such in New South Wales. The Hells Angels have been linked with drug trafficking and production, as well as a host of violent crimes including murder, in Australia.

Background The Hells Angels expanded to Australia in 1975, initially establishing chapters in Melbourne and Sydney, and now have approximately 250 members and 14 chapters in the country. The club's activities in Australia have traditionally included drug trafficking, prostitution, armed robbery, arms trafficking, fencing stolen goods and murder-for-hire, but they have more recently moved into legitimate businesses such as gyms, tattoo parlours, haulage companies, and the security industry. Police allege the Hells Angels use mainstream industries to launder existing funds and to exploit new income streams, using the strategies they developed during a series of gang wars to intimidate business competitors. The Australian Hells Angels have aligned themselves with the Coffin Cheaters,Police raid Coffin Cheaters bikie clubhouse in Braeside Tammy Mills, The Age (21 August 2015) Immortals,The key players and factions in the power struggle between bikie heavyweights Comancheros & Hells Angels Herald Sun (4 October 2013) Red Devils, Satans Soldiers, Vikings and the Prisoners of War, a prison gang operating inside HMP Barwon, while they have been involved in conflicts with the Bandidos, Comancheros, Diablos, Finks, NomadsAustralian Bikie Gangs: Complete List of Outlaw Motorcycle Clubs Amy Farrugia, New Idea (30 March 2019) and Notorious.Bikie bomb blast 'may be revenge' Jonathan Dart and Geesche Jacobsen, Sydney Morning Herald (5 February 2009) The first conflict was with the Rebels after the Hells Angels demanded that the Rebels change their colors from red and white (the same color as the Hells Angels). The conflict ended with the Rebels beating a Hells Angels chapter president in his house with a baby's pram. In 2006, the Canadian journalists Julian Sher and William Marsden wrote: "The Hells Angels remain the most powerful bikie gang in the country, even though they have fewer members than other gangs such as the Rebels or the Gyspy Jokers.".

By state New South Wales Members of the rival motorcycle gang, the Comancheros, and members of the Hells Angels were believed to be involved in a clash on a Melbourne to Sydney flight and subsequently at Sydney Airport on 22 March 2009. The clash resulted in one man, Hells Angels associate Anthony Zervas, being beaten to death. Police estimated as many as 15 men were involved in the violence. Documents released by NSW Police detail the brawl as a result of the Comanchero national president Mick Hawi and the Hells Angel national president Derek Wainohu being on the same flight from Melbourne. Four suspects were arrested as a result of the altercation. As a result of heightening violence, New South Wales Premier Nathan Rees announced the state police anti-gang squad would be boosted to 125 members from 50. The main suspect in this case, Mick Hawi was sentenced to jail and then released a few years later. Then he was himself shot dead in downtown Sydney in 2018

On the night of March 29, 2009, Hells Angels member Peter Zervas, the brother of the man killed during the Sydney Airport Brawl a week earlier, was shot and injured as he left his car outside his home.

On July 20, 2011, a NSW judge dismissed a bid by the state's police commissioner to have the Hells Angels Motorcycle Club declared a criminal organization, under laws introduced to NSW parliament in 2009 allowing the court to declare criminal organizations as declared organizations.

On 8 July 2013 Tyrone Lee Slemnik, 37, was standing guard outside the home of Hells Angels Sydney chapter president Suvat Sarimsaklioglu when he was gunned down as shots were fired from a passing car. No one has been held responsible for his death and there have been no arrests as a result. Following the death of Slemnik, Sarimsaklioglu, the club president was charged with the possession of a military-style assault weapon, found in the boot of a taxi for which he was later acquitted of. His lawyer, Omar Juweinat told the court that the police were unable to prove that Sarimsaklioglu knew the firearm was present. Police feared that the weapon was to be used for retaliation.

Following his acquittal for those matters, in April 2016 Sarimsaklioglu stood trial, with two others for abduction for which he was also found not guilty. In November 2017, he was charged for the supply of a large commercial quantity of drugs. He was held in custody for over 18 months before his trial was derailed by the prosecution, prompting lawyer Omar Juweinat to complain that "civil liberties are quickly eroding".

In January 2023, Sarimsaklioglu was sentenced to three years and two months imprisonment, with a non-parole period of 19 months, backdated to November 2021 due to time already served. The sentence related to his arrest at Surry Hills in a taxi along with another man and a backpack full of illicit drug precursor gamma-Butyrolactone in June 2021. Text messages showed they planned to supply drugs.

Queensland The Brisbane chapter of the Hells Angels was founded on 27 March 1997.

Bruno and Nuno Da Silva, two Portuguese immigrant twin brothers and former Brisbane Hells Angels members, were arrested following a police surveillance operation and pleaded guilty to trafficking methylamphetamine from June 2012 to October 2013. The brothers operated from an East Brisbane locksmith business and passed a percentage of their drug earnings to the Hells Angels at weekly meetings, although they had left the club at the time of their arrest. In December 2015, Bruno was sentenced to nine years imprisonment, while Nuno was sentenced to seven years.

In 2012, Peter Sidirourgos and Zeljko "Steve" Mitrovic, both senior Hells Angels members in Sydney, were granted Nomad status and spearheaded a push into the Gold Coast, founding a chapter in the suburb of Burleigh Heads. Police stated in 2015 that the Hells Angels were now the most active club on the Gold Coast after anti-bikie laws weakened the rival Bandidos and Finks (a club later patched over to the Mongols), who had previously been more prominent in the area.

The Hells Angels were one of 26 motorcycle clubs designated as criminal organizations in the state of Queensland under the Vicious Lawless Association Disestablishment (VLAD) Act, which was passed on October 16, 2013, and went into effect immediately.

South Australia The first HAMC chapter in South Australia was formed in Adelaide on 1 October 1983.

Similar to the case in Queensland, the Hells Angels were also declared a criminal organization in the state of South Australia along with nine other motorcycle clubs under legislation that came into force in August 2015. Under the laws, it is an offence for members of these organizations to gather in groups of three or more in public or wear gang colours and logos. Five alleged Hells Angels members and prospects became the first to be charged under the laws after they were arrested in a series of raids across Adelaide on December 31, 2015.

Popular criminal Vince Focarelli was kicked out of the Hells Angels. He then joined other clubs including the Comancheros, and set up his own club. He left the Comancheros later. Him and his son Giovanni were shot at by unknown assailants in 2012. Vince was sent to the Royal Adelaide Hospital and his son died. He has refused to name any suspects even though this was not the first time he was targeted. While Vince was in hospital, he was visited by friends who are Finks members. Some Finks members also visited the funeral of Giovanni.
