Terrorism in Australia deals with terrorist acts in Australia as well as steps taken by Australian governments to counter the threat of terrorism. In 2004 the Australian government has identified transnational terrorism as also a threat to Australia and to Australian citizens overseas. Australia has experienced acts of modern terrorism since the 1960s, while the federal parliament, since the 1970s, has enacted legislation seeking to specifically target terrorism.
Terrorism is defined as "an action or threat of action where the action causes certain defined forms of harm or interference and the action is done or the threat is made with the intention of advancing a political, religious or ideological cause".
A number of terrorists attacks have occurred in Australia.
Two men shot dead four people and wounded seven more, before being killed by police and military officers. At the time of their attack, they raised the flag of the Ottoman Caliphate, later the Turkish flag to identify their cause. Neither of the men were members of any official armed force. In today's parlance, their attack would be described as an act of Lone wolf (terrorism). The two men were later identified as being Muslims from the British colony of India, modern day Pakistan (some sources incorrectly identify them as Turkish).
The Embassy of the USSR was attacked by a crude bomb on 17 January 1971 in Canberra. 
The Sydney Yugoslav General Trade and Tourist Agency bombing occurred in Haymarket, Sydney on 16 September 1972; the attack injured sixteen people. The perpetrators were never found or charged.
The Sydney Hilton Hotel bombing occurred on 13 February 1978; a bomb exploded outside the Hilton Hotel in Sydney, which was hosting the first Commonwealth Heads of Government Regional Meeting. Two garbage collectors and a police officer were killed and eleven others were injured.
On 23 June 1980, David Opas, a judge of the Family Court, was shot dead outside his home. In March 1984, a bomb destroyed the home of fellow judge Richard Gee, who survived. In April, a bomb exploded in the Family Court building in Parramatta. In July, the wife of judge Ray Watson was killed when a bomb exploded on their doorstep. In July 1985 a bombing at a Jehovah's Witness hall killed the minister, Graham Wykes.
On 17 December 1980, Sydney Turkish Consul General Şarık Arıyak and his security attaché Engin Sever were assassinated by two people on motorcycles wielding firearms in Sydney. The Justice Commandos for the Armenian Genocide claimed responsibility but the culprits were never identified and no charges were laid. The Consul General was gunned down despite having taken precautions in the form of not travelling in the official consulate Mercedes Benz vehicle and instead being chauffeured in the trailing security attaché's car.
Throughout the 1980s, West Australian neo-Nazi group "The Australian Nationalist Movement", led by Jack van Tongeren, engaged in a series of bombings of Asian restaurants and businesses, political violence, murder of a suspected informant and other acts to intimidate the Asian population. Van Tongeren was eventually imprisoned for a long period of time until his release in the early-mid 2000s. He resumed his activities until he was re-arrested in 2004 as part of Operation Atlantic, prompting a judge to order him to leave the state.
The bombing of the Israeli Consulate and Hakoah Club in Sydney occurred on 23 December 1982. The two bombings occurred on the same day within five hours of each other. The initial case led to a single arrest though charges were later dropped. In 2011, the NSW police and Australian federal police reopened the case citing new leads.
The Melbourne Turkish consulate bombing occurred on 23 November 1986; a car bomb exploded in a carpark beneath the Turkish Consulate in South Yarra, Victoria, killing the bomber who failed to correctly set up the explosive device. Levon Demirian, a Sydney resident with links to the Armenian Revolutionary Federation, was charged over the attack and served 10 years.
− On 16 July 2001, Peter James Knight, described as an "obsessive anti-abortionist" who lived alone in a makeshift camp in rural New South Wales, attacked the East Melbourne Family Planning clinic, a privately run clinic providing abortions, carrying a rifle, and large quantities of kerosene and lighters. He shot and killed a security guard at the clinic before his capture and arrest. He was charged and convicted of murder, and was sentenced to life imprisonment with a non-parole period of 23 years. Australian terrorism academic Clive Williams listed the attack amongst incidents of politically motivated violence in Australia.
On 23 September 2014 an 18-year-old man, Numan Haider, was shot and killed by police outside Endeavour Hills police station. Victoria Police Assistant Commissioner Luke Cornelius said Haider had been asked to come to the police station to discuss behaviour "which had been causing some concern". When the man arrived outside the station, he stabbed the two officers as they went to meet him. The two stabbed officers, one from Victoria Police and one from the Australian Federal Police, were working together as part of a joint operation on counter-terrorism between the AFP and Victoria Police. Haider was found to be carrying two knives and an Islamic State flag.
On 15 December 2014, a self-proclaimed Muslim sheikh, Man Haron Monis, took 17 people hostage inside a chocolate café in Sydney. He forced hostages to hold up a jihadist black flag against a window of the café. On the early hours of 16 December, police breached the café and fatally shot Monis following the escape of several hostages. Two hostages also died, while another four people, including a police officer, were injured in the incident.
The designation of the 2014 Sydney hostage crisis, also known as the Sydney Martin Place siege, has been subject to debate among terrorism experts and news commentators. Initially, during the early stages of the incident, the Australian government and NSW authorities did not label the event as a terrorist attack; however, as the siege continued, NSW police authorised the engagement of the state's counterterrorism task force, treating the incident as an act of terrorism. Commentators have debated whether the perpetrator of the attack, Man Haron Monis, was in fact a terrorist and whether his actions can be classified as an act of terrorism. One terrorism expert described Monis' actions as those of a "lone wolf terrorist ... driven by a desire for attention and to be in the spotlight." Another wrote in an opinion column that the attack "was very different from first-generation or second-generation terrorist attacks—but it was terrorism, and terrorism of a brutal and more unpredictable sort." Scott Stewart supervisor of the analysis of terrorism and security issues for Statfor said that this hostage-incident exhibits many of the elements associated with grassroots terrorism. By contrast, criminologist Mark Lauchs stated that the event "was not about religion and neither was it a terrorist attack." Media outlets have also provided conflicting designations for Monis; John Lehmann, editor of The Daily Telegraph, wrote how Monis filled the criteria of an Islamic State terrorist, while a columnist for The Guardian wrote how the designation of a terrorist is misplaced and would only serve the interests of ISIL. On 15 January 2015, Australia's Treasurer Joe Hockey declared the siege in Sydney's Martin Place as a terrorist incident for insurance purposes.
The difference between terrorism and terrorising acts was noted in one analysis as "enormously important"—in Monis's case, terrorism "was clearly an element, but he was coming to the end of his rope with a variety of legal processes; there was clearly some mental instability." One argument was that the gunman's lack of ties to any movement did not preclude his being a terrorist as it is "an inclusive club".
Nick O'Brien, Associate Professor Counter Terrorism at Charles Sturt University has said Islamic State's magazine claim that the Sydney siege gunman is a righteous jihadist should not be lightly dismissed. Dr David Martin Jones, Senior Lecturer at the School of Government, University of Tasmania has said not to underestimate the politically destabilising intent of Monis' lone-actor violence, as it is a considered-tactic and a strategic-goal of ISIL.
On 2 October 2015, a 15-year-old Iranian-born Iraqi-Kurdish boy shot dead a 58-year-old accountant, who worked for the New South Wales Police Force, outside the Parramatta Police headquarters. The boy then shot at special constables guarding the building, and was shot dead by them. NSW Police Commissioner Andrew Scipione said "We believe that his actions were politically motivated and therefore linked to terrorism." Four men were arrested and charged in relation to the shooting.
On September 10 a man was attacked in a park in Minto New South Wales. He was chased and repeatedly stabbed or slashed with a knife. The offender was charged with attempted murder and with committing a terrorist act.
On 7 April 2017, a pair of 15 and 16 year old boys entered a service station in the small town of Queanbeyan in NSW and stabbed 29-year old Zeeshan Akbar of Pakistani descent, who died at the scene soon after. Three other men were also attacked and injured at the scene. The 16-year old's mother had told police that she believed that her son had been radicalised in recent weeks and that he sympathised with Islamic State and had also posted concerning posts on Facebook. The police are treating this as an act of terrorism and an investigation is under way.
On 5 June 2017, 29 year old Somali-born Yacqub Khayre shot dead receptionist Kai Hao in the foyer at a serviced apartment complex in the suburb of Brighton in Melbourne. He then took a female escort hostage in an apartment. He contacted both the police and the media. Police responded and Khayre died in a shoot out with three police officers wounded. Khayre had referred to ISIS and al-Qaeda in a phone call to the media. In 2010 he had been acquitted of the Holsworthy Barracks terror plot.
Australian police have disrupted a significant number of terrorism plots since 2014.
In 1975, the Palestinian Black September terrorist group and the Australian branch of the Popular Front for the Liberation of Palestine (PFLP) terrorist group plotted to assassinate future Australian Prime Minister Bob Hawke, then Australian Labor Party president, along with a number of notable journalists seen as being pro-Israel. A Black September member visited Australia under the guise of a journalist and was provided with materials from Australian PFLP members and returned to Israel; the Black September member who intended to carry out the attack was killed by Israeli forces before he could return to Australia.
Faheem Khalid Lodhi is an Australian architect accused of an October 2003 plot to bomb the national electricity grid or Sydney defence sites in the cause of violent jihad. He was convicted by a New South Wales Supreme Court jury in June 2006 on terrorism-related offences, namely:
In his judgement, Justice Anthony Whealy illustrated that Lodhi's behaviour breached the rules under the Anti Terrorism Act 2004 (Cth), Crimes Act 1914 (Cth), the Criminal Code and the Crimes (Internationally Protected Persons) Act 1976 (Cth) 
His intended targets were the national electricity supply system, the Victoria Barracks, HMAS Penguin naval base, and Holsworthy Barracks. Justice Anthony Whealy commented at sentencing that Lodhi had "the intent of advancing a political, religious or ideological cause, namely violent jihad" to "instill terror into members of the public so that they could never again feel free from the threat of bombing in Australia."
Accordingly, Whealy said the sentence to be imposed "must be a substantial one to reflect the important principles of deterrence and denunciation. In relation to count 2 the appropriate sentence, in my view, is one of imprisonment for a term of 20 years. The sentence is to commence on 22 April 2004 and to expire on 21 April 2024." 
Neil Prakash is a former Buddhist from Melbourne who became a jihadist and changed his name to name Abu Khaled al-Cambodi.
He was linked to a number of domestic terror threats, including an alleged Anzac Day terror plot in Melbourne and the shooting death of NSW police worker Curtis Cheng in western Sydney in 2015. Later, he fled to Syria and became a senior recruiter for the Islamic State in Iraq and Syria, appearing in propaganda videos and magazines with the intention of recruiting people to commit acts of terrorism.
Prakash was reportedly killed by a targeted US air strike in northern Iraq in May 2016. Australian Prime Minister Malcolm Turnbull commented: "Neil Prakash's death is a very, very positive development in the war against Daesh and the war against terror". The Herald Sun later reported that Australian security officials were "almost certain" that Prakash had not been killed in the airstrike and had continued to act as a recruiter for the group. In November 2016, Australian counter-terrorism officials confirmed that Prakash was still alive, and had been arrested after attempting to enter Turkey from Syria.
Khaled Cheikho, Moustafa Cheikho, Mohamed Ali Elomar, Abdul Rakib Hasan and Mohammed Omar Jamal were found guilty of conspiring to commit a terrorist act or acts. They were jailed on 15 February 2010 for terms ranging from 23 to 28 years.
In September 2008, of an original nine defendants, five men including the Muslim cleric, Abdul Nacer Benbrika were convicted of planning a terrorist attack. During the trial, the jury heard evidence of plans to bomb the 2005 AFL Grand Final, 2006 Australian Grand Prix and the Crown Casino, as well as a plot to assassinate then Prime Minister John Howard.
On 4 August 2009, four men in Melbourne were charged over the Holsworthy Barracks terror plot, an alleged plan to storm the Holsworthy Barracks in Sydney with automatic weapons; and shoot army personnel or others until they were killed or captured. The men are allegedly connected with the Somali-based terrorist group al-Shabaab. Prime Minister Kevin Rudd subsequently announced a federal government review of security at all military bases.
In December 2011 Justice Betty King sentenced three of the men to 18 years in prison with minimum terms of 13 1/2. She said that they were all "unrepentant radical Muslims and would remain a threat to the public while they held extremist views".
Mohammed Abderrahman aka Willie Brigitte, is a French Islamist al-Qaeda recruit who resided with Faheem Lodhi while in Australia in 2003, during which time he married a former Australian Army signaller. He was arrested by Australian immigration compliance officials in Sydney six weeks after the marriage and deported to France.
His wife said before a French investigating judge that at times he had 'bombarded' her with questions on the subject of her military knowledge and career. She reports that she rebuffed such questioning or responded minimally 'so that he would leave [her] in peace' and that she burned three of her notebooks originating from the period of her military service in East Timor as a precaution. She reported his anger about her taking such precautions, his presumption to forbid her from further similar actions, and she exactly confirmed his repeated statement of the opinion that "Allah and all Muslims need this information" in order to obtain information of a military character from her.
In December 2006, it was reported that a basis for French terrorism-related charges laid against him was the allegation that he aided the murderers of Ahmad Shah Masood by supplying them with false identity documents.
In early 2007 he was in custody as a terrorism suspect in France where prosecutors called for him to be sentenced to 10 years' imprisonment for his admitted involvement in a terrorist organisation.
On 15 March 2007 Brigitte was found guilty and received a nine-year prison sentence.
On 28 August 2006, following the quashing of his terrorism convictions, Joseph T. Thomas (also dubbed "Jihad Jack") was the first person to be issued with a control order under the Australian Anti-Terrorism Act 2005 after written consent was provided by the Australian Attorney-General Philip Ruddock. In December 2007 a control order was issued against David Hicks to ensure that he was monitored upon his release.
Sevdet Besim was arrested on 18 April 2015. Aged 18 and born to parents of Albanian origin, he planned to drive car into and kill, then behead, a law enforcement officer on ANZAC Day in Melbourne. He was subsequently sentenced to 15 years’ imprisonment on 5 September 2016.
On 31 October 2017, Tamin Khaja plead guilty to planning a terrorist attack on targets in Sydney that included the Timor Army Barracks and Sydney West Trial Courts. He was arrested in May 2016 as he was attempting to obtain firearms, explosives and an Islamic State flag.
On 3 November 2017 Sulayman Khalid, also known as "Abu Bakr", was sentenced to up to 22-years and 6 months jail in the NSW Supreme Court by Justice Geoffrey Bellew. He was the leader among five of six conspirators who were sentenced in connection to a plot between 7 November and 18 December 2014 that targeted government sites, including the Lithgow Correctional Centre and an Australian Federal Police building in Sydney. Jibryl Almaouie, Mohamed Almaouie, Farhad Said and an unnamed teenager were all sentenced to jail terms for their part. Ibrahim Ghazzawy, the sixth conspirator was earlier in 2017 sentenced to a minimum of 6 years and 4 months. Khalid appeared on the SBS program Insight in 2014,where he said said Islamic State only wanted to bring "justice, peace and humanitarian aid to the people". He later stormed off the set.  Khalid was arrested on 23 December 2014 by Joint Counter Terrorism Team members as part of Operation Appleby.
The Islamic State of Iraq and the Levant (ISIL), proscribed by the government as a terrorist organisation, has targeted Australian Muslims for recruitment. Making use of social media, recruiters target those vulnerable to radicalisation, and encourage local jihad activities. Some of those targeted have been minors, including a teenager who was arrested in Melbourne in May 2015 for plotting to detonate home-made bombs. In June 2014, the government claimed that roughly 150 Australians had been recruited to fight in the conflicts in Syria and Iraq. A list released in April 2015 showed that most were young males who have come from a range of occupations, including students. It was also reported at the time that 20 Australians had been killed fighting overseas for terror groups, with 249 suspected jihadists prevented from leaving Australia. The Australian Border Force Counter-Terrorism Unit, tasked with stopping jihadists from leaving the country, had cancelled more than 100 passports by the end of March 2015. Several jihadists have expressed the desire to return to Australia, but Prime Minister Tony Abbott has said that any who do would be prosecuted on their arrival.
On 1 September 2016 Hamdi Alquidsi was sentenced to 8 years jail (6 minimum) by Justice Christine Adamson. In July he was found guilty of seven counts of "supporting engagement in armed hostilities" in Syria. Two men he helped travel to Syria were killed there, two others have returned to Australia. The fate of another two is unknown, while the last never left. Alqudsi will be eligible for release in July 2022.
In the early hours of 18 September 2014, large teams of Australian Federal Police (AFP) and other security agencies conducted search operations in both Sydney and Brisbane. Australian Prime Minister Tony Abbott has alluded to an alleged plot aimed at conducting a random act of terrorism as the reason for the police action. This action is described as the largest in Australian history to date. One man arrested, from Guildford, allegedly conspired to commit a "horrifying" terrorist act with a man believed to be the most senior Australian Islamic State leader.
On 30 September 2014 there were more raids in Melbourne. The AFP executed seven search warrants in Broadmeadows, Flemington, Kealba, Meadow Heights and Seabrook. Over 100 officers from Federal and State police forces took part. A man from Seabrook will be charged with "intentionally making funds available to a terrorist organisation knowing that organisation was a terrorist organisation", AFP Assistant Commissioner Gaughan said. The man is alleged to have provided money to a United States citizen who was fighting in Syria.
On 10 February 2015 two men were arrested in Fairfield, New South Wales, and charged with "Acts done in preparation, for, or planning terrorists acts". On the morning of 10 February police were informed the two were planning a terrorist attack. They were quickly placed under surveillance and tracked. When they purchased a hunting knife from a store about 3:00 pm, NSW Joint Counter Terrorism Team (JCTT) forces decided to intervene and soon after 4:00 pm the men were arrested.
The men were a 24-year-old student from Iraq, and a 25-year-old nurse who moved from Kuwait in 2012. The two were unknown to police until the tip-off. The men's residence, a vehicle and places of work were searched. They were found with a machete, a hunting knife, a homemade Islamic State flag and "a video which depicted a man talking about carrying out an attack", according to NSW Police Deputy Commissioner (Specialist Operations) Catherine Burn. One of the men arrested appeared in the video.
Burn also said: "We will allege that both of these men were preparing to do this act yesterday" and "We believe that the men were potentially going to harm somebody, maybe even kill somebody ...".
The JCTT investigation has been given the code name Operation Castrum.
|“||engaging in an act in preparation for, or planning, a terrorist act contrary to section 101.6 of the Criminal Code(Cth) and possess things connected with a terrorist act, contrary to section 101.4 of the Criminal Code (Cth)||”|
Three alleged improvised explosive devices were found and rendered safe in a park by controlled detonation. The teenager appeared in court on 11 May and was remanded to reappear on May 26. 'Operation Amberd' was formed, and investigations made for 9 days, after a call to a security hotline. AFP and Victorian police of the Melbourne Joint Counter Terrorism Team (JCTT) carried out the raid. AFP Deputy Commissioner Mike Phelan said: "We can absolutely guarantee we have stopped something."
On 23 December 2016 seven people were arrested in Melbourne for plotting an attack on Christmas Day. Properties were raided at Campbellfield, Dallas, Victoria, Flemington, Gladstone Park, and Meadow Heights. The would-be terrorists planned to attack the Federation Square, Flinders Street railway station, and St. Paul's Cathedral, three landmarks clustered in the centre of Melbourne. An explosive device and other weapons were to be used.
In late February 2017 a man was arrested at Young, New South Wales after an 18-month investigation. The man is a 42-year-old electrician and Australian citizen. He is alleged "... to have been researching how to develop laser missile detection equipment for IS and helping the extremists develop their own destructive missile arsenal". He appeared the same day at Young Local Court charged with two foreign incursion offences, and a count of "failing to comply with an order to assist access to data".
Prior to the 1960s, there had not been any act in Australia that could accurately be deemed "terrorism" in the modern political and strategic sense of the word. Politically motivated violent incidents were rare, usually isolated, and for the most part driven by issues arising from political legislation, greed, or individuals being singled out, such as the attempted assassination of Australian Labor Party Leader Arthur Calwell in 1965 over his Vietnam War stance. Likewise the 1968 attack on the US Consulate in Melbourne was also regarded to be an isolated incident protesting the US involvement in Vietnam. The two exceptions to this state of affairs would be the assassination attempt on the Duke of Edinburgh in 1868 by an Irish Nationalist named O'Farrell, who was later executed for his crime, and an attack in Broken Hill in 1915 by Afghan supporters of the Sultan of Turkey.
Although it had known sporadic acts through its history, and examples of modern terrorism for almost a decade, Australia did not introduce terrorism specific laws into Parliament until the late 1970s. In 1977, after a three-year inquiry into Australia's intelligence services, Justice Robert Hope delivered his Royal Commission on Intelligence and Security (RCIS). The RCIS recommended amongst other things that the Australian Security Intelligence Organisation (ASIO) areas of investigation be widened to include terrorism. A further Protective Security Review by Justice Hope in 1978 following the Sydney Hilton bombing designated ASIO as the government agency responsible for producing national threat assessments in the field of terrorism and politically motivated violence.
Since then, successive governments have reviewed and altered the shape of both legislation and the agencies that enforce it to cope with the changing face, threat and scope of terrorism. It was not until after the attacks of 11 September 2001, however, that Australian policy began to change to reflect a growing threat against Australia and Australians specifically. Until then the view held from the 1960s had been that terrorist actions in Australia were considered as a problem imported from conflicts overseas and concerned with foreign targets on Australian soil.
In 2004, the Howard Government introduced into Parliament three anti-terrorism bills, collectively called the Australian anti-terrorism legislation, 2004, and in 2005 the Australian Anti-Terrorism Act 2005 was passed.
Before 2006, the last legislation to be brought into effect was the Anti-Terrorism Act (No. 2) 2005.
The Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (Cth) came into law on 12 December 2006, and extends the regulatory regime imposed by the Financial Transaction Reports Act 1988.
New anti-terror laws were introduced in three stages in 2014:
In the wake of the 2 October 2015 shooting death of a civilian police employee, the New South Wales government requested legal changes to allow control orders on people aged 14 and over. Attorney-General George Brandis agreed to the changes. The NSW Council for Civil Liberties criticised the proposal. The councils president Stephen Blanks said: "The proposed laws are undoubtedly going to be in breach of human rights standards,"
In November 2015 it was stated that New South Wales police were being retrained to "...shoot terrorists on sight rather than try to contain them and negotiate,...".
As at January 2015, there were 20 organisations designated and banned, by a court or a government department, for active involvement in terrorism. All but one of those organisations are Islamist. Identification of an organisation as a terrorist organisation may result from a prosecution for a terrorist offence, or from a listing determined by the Attorney-General of Australia.
A number of terror organisations and terror cells have operated in Australia, their activities have varied from fundraising and providing material support for terror activities overseas, to plotting and executing domestic terrorism.
An Algerian man, known as "Ahmed Y", arrived in Australia in the late 1980s. Ahmed established a small militant group in Australia in 2001 and supported the idea of establishing an Islamic State in Australia and the use of violence against Australians.:14
The Lashkar-e-Taiba, a proscribed terrorist organisation based out of Pakistan, set up a terror cell in Australia. French convert to Islam, Willie Brigitte, accused of planning an attack in Australia, was trained by Lashkar-e-taiba.
A short-lived terror cell, known as Mantiqi 4, existed in Australia for several years. The group was sponsored by Jemaah Islamiah (JI), a terrorist group known for their attacks in Indonesia, and was established by Abdul Rahim Ayub, a member of Jemaah Islamiah.:111 Ayub resided in Perth during the late 1990s all while being an active JI member, travelling and attending the group's leadership conferences in Indonesia. In contrast to the Jemaah Islamiah's other cells in Southeast Asia, the Mantiqi 4 cell was less of a focus for the organisation.:38
The activities of the Australian branch of JI included fundraising among the local Indonesian community in Australia. Jemaah Islamiah leadership also expressed intent on identifying targets in Australia to be attacked by Al Qaeda.:128
A group referred to as the "Syrian syndicate" has been investigated for sending Australian Muslims to fight in the Syrian Civil War. Australian Counterterrorism Police have investigated Wassim Fayad in connection to an attempt to ram an ATM during the 2011 Auburn riots. It is suspected that the funds were to be used in connection to local efforts of involvement in the Syrian conflict.
ABC News reported that the Al Qaeda group Jabhat al-Nusra was likely to be active in Sydney owing to the quick rise in ranks of Abu Sulayman al-Muhajir, a Sydney man who joined the group in Syria. Abu Sulayman was designated as a "Specially Designated Global Terrorist" by the United States in 2016.
In 2015 it was reported that more than 20 Australians who have fought with ISIL have returned and are being monitored by security agencies. Foreign Minister Julie Bishop has said, "there is a risk they will come back as battle-hardened experienced terrorists . . . and try to carry out terrorist attacks".
A number of incidents relating to the Islamic State of Iraq and the Levant (ISIL) terrorist group have involved Australians and garnered the attention of the Australian public. ISIL is a militant Sunni group which has been proscribed by Australian authorities as a terrorist organisation.
In 2014, two Australian Islamic extremists made a propaganda video encouraging Australians to join the ISIL, According to the Australian government, up to 150 Australians "have been or are currently overseas fighting with extremists in Iraq and Syria." Some of their activities are thought to be war crimes. One Australian jihadist, Khaled Sharrouf, posted a picture of himself, and another of his son, holding a decapitated soldier's head.
ISIL recruited Australian nationals for terror attacks in the Middle East including suicide bombings as late as March 2015. 18 year old Jake Bilardi, known as Jihadi Jake, converted to Sunni Islam. He died on 11 March 2015 when he carried out a suicide bombing in Ramadi, Iraq.
The Attorney-General Senator George Brandis has expressed concern that those fighting jihad, then returning from the Middle East, represent, "the most significant risk to Australia's security that we have faced in many years." The Australian Security Intelligence Organisation (ASIO) is concerned that Australians fighting jihad may return home to plan terror attacks. In October 2014, ISIL published an online video in which a teenage Australian Jihadi, Abdullah Elmir, threatened the United States and Australia, naming US president Barack Obama and Australian prime minister Tony Abbott as targets.
On 6 September 2016 ISIL published a new online magazine in which they urged 'lone wolves' to carry out attacks:
|“||Kill them on the streets of Brunswick, Broadmeadows, Bankstown, and Bondi. Kill them at the MCG, the SCG, the Opera House, and even in their backyards,||”|
The same statement was published in other languages naming locations in France, Germany and Indonesia.
Two days later on 8 September a man was detained at the Sydney Opera House after acting suspiciously. He was later charged with "threatening to destroy or damage property."
In 2015 the New South Wales Police Force's Counter Terrorism and Special Tactics Command assessed that members of the anti-government sovereign citizen movement posed a potential terrorist threat. At the time there were reported to be 300 members of this movement in the state. While there had been no incidents of violence associated with sovereign citizens in Australia at that time, the NSW Police were concerned that members of the movement were becoming radicalised and could commit attacks such as those made by sovereign citizens in the United States.
Researchers have observed that Muslims in Australia have become a "stigmatised minority", subject to increased surveillance by state authorities as well as public discourse that constructs Muslims as a potential terrorist threat. Researchers term this the "suspect community" thesis. Researchers study how Muslims perceive themselves as a suspect community and how this influences their support for counter-terrorism efforts.

Law changes requested by the New South Wales Government and agreed to by Attorney-General George Brandis could also see young people closely monitored under potential laws aiming to lower the age of control orders from 16 to 14.
IS propaganda published on Thursday claimed that Jake Bilardi, 18, died in a co-ordinated series of suicide bombs in Ramadi in Anbar province, Iraq.
