On 6 December 2024, at approximately 4:10 am local time, an arson attack took place at the Adass Israel Synagogue of Melbourne in Ripponlea, a suburb of Melbourne, Australia. The resulting fire injured one member of the synagogue and caused significant damage to the building. On 9 December 2024, Victoria Police stated the incident was being treated as a terrorist attack. The investigation of the attack was assigned to the Joint Counter-Terrorism Team consisting of the Australian Federal Police, Victoria Police and the Australian Security Intelligence Organisation. The perpetrators of the attack reportedly used an accelerant and followed by spreading that throughout the interior of the building with a broom before lighting the accelerant fluid.

On 26 August 2025, Australian Prime Minister Anthony Albanese announced that ASIO have determined Iran was allegedly involved in planning the attack. The attack was one of multiple 2024 Iranian operations inside Australia.

Background

Adass Israel Synagogue

The targeted synagogue in the December 2024 attack was the Orthodox Adass Israel Synagogue of Melbourne, located in Ripponlea, Victoria. It was built in 1965, designed by Ernest Fooks, and opened on 19 September 1965. It is part of the Adass Israel Congregation, a Jewish group in Melbourne that traces its origins to a split in the Elwood Talmud Torah Hebrew Congregation in 1939/1940. Some of its early members were boys and men who had been sent to Australia by the British on the infamous Dunera in 1941.

According to Philip Zajac, President of the Jewish Community Council of Victoria, the Adass Israel congregation is apolitical with regards to the State of Israel. When the sounding electoral boundaries were reviewed, one of the discussion papers presented stated that "Adass Israel’s political interests differ considerably in many ways" compared to neighbouring Jewish communities in Melbourne, and "Of particular note is the non-Zionist nature of the Adass Israel community; indeed it has ties to groups that are openly anti-Zionist".

The Synagogue was previously vandalised in 1989,Kleerekoper, Victor (1989). More anti-semitic daubings. The Australian Jewish News. 10 November 1989. Accessed 13 January 2025. and it was severely damaged in an arson attack on 1 January 1995. The synagogue had last been the subject of an arson in 1995, in which all the Torah scrolls were kept safe from the fire. In that case, police did not find any evidence that antisemitism or racism motivated the crime.

Elsewhere in Australia

The 2024 arson attack at Adass Israel Synagogue took place in a period where the Australian Government's National Terrorism Threat Level was at probable after being raised in August 2024, indicating that there is a greater than 50% chance of a terrorist attack or attack planning taking place in Australia's near future. The threat level had previously been at probable level since shortly after November 2015's Paris terror attacks until 2022 when it was lowered to possible.

Following the Gaza war succeeding the October 7 attacks, vandalism and intimidation directed at synagogues occurred at various locations in Australia. In an incident occurring on 8 October 2023, in New South Wales (a neighbouring state to the North of Victoria), two individuals walked past a synagogue and shouted “Allahu Akbar”, before saying that they would “blow up the synagogue”.A CSG Analysis of Reported Antisemitic Incidents in Australia in 2023. Community Security Group. 2024. Accessed 18 January 2025. On 11 October 2023, in Melbourne, a synagogue received a bomb threat.2023 Victorian Antisemitism Report. Jewish Community Council of Victoria and the Community Security Group. On 23 November 2023, in Western Australia, an individual threw two glasses of red paint at a synagogue. In December 2023, hoax bomb threats were made to several synagogues across Australia. On 26 November 2024, a Chabad synagogue in St Kilda, Melbourne was vandalised with pro-Palestinian and antisemitic graffiti.

Attack In the early hours of 6 December 2024, two masked men entered the Adass Israel Synagogue of Melbourne in Ripponlea. The men began pouring an accelerant on the floor and spreading it throughout the interior of the building with a broom when they were disturbed by a congregant who was attending the synagogue. The two perpetrators set the accelerant alight just before 4:10 am and fled the scene in a stolen Volkswagen Golf. The fire spread quickly causing extensive damage to the inside of the synagogue and collapsing part of the roof. Two members of the synagogue were inside at the time. One member who left the synagogue to call police sustained minor injuries to his hands after returning to the synagogue.

Dozens of emergency service crews, including 65 firefighters, were called to the synagogue shortly after the blaze first started. Firefighters spent more than an hour containing the blaze. A crime scene was established after the fire had been put out and members of the synagogue where allowed to enter in the afternoon of 6 December 2024 to retrieve the Torah scrolls, holy books, tallits, tefillin, other artefacts and some personal items. Police estimate the fire caused damage in excess of A$20 million.

Aftermath On 9 December, in the wake of the synagogue attack, the AFP established Taskforce Avalite to investigate antisemitism in Australia. The Australian Security Intelligence Organisation (ASIO) also announced it would be assisting the taskforce in its investigation. Following the incident, police in Canberra increased patrols around synagogues in the nation's capital. The Sydney Jewish community organised a demonstration on 15 December 2024, at Martin Place, protesting the Australian government's inadequate response to antisemitism.Panagopoulos, J. (2024). "Many in Jewish community fear Australia is at a ‘tipping point’." The Australian. 15 December 2024.Gusmaroli, D. (2024). "Hundreds join rally in Martin Place to end anti-Semitism in Sydney." The Daily Telegraph. 15 December 2024. On 17 December 2024, Victorian Premier Jacinta Allan announced new measures impacting public protests as part of an effort to prevent antisemitic behaviour.Alfares, M. (2024). "APAN blasts Victorian protest bans as an attack on liberty" The Australian. 17 December 2024. The proposed laws would establish safe access in close proximity to places of worship and prohibit disturbances of religious gatherings. There are ongoing investigations on some of the reported antisemitic attacks. Anthony Albanese suggested that the attacks may have involved actors without ideological commitment being funded externally.

Arrests On 16 July 2025, the Victorian Joint Counter Terrorism Team (JCCT) charged a 20-year-old man from Melton South over the theft of the blue Volkswagen Golf used in the arson attack. The Golf had previously been used in another arson attack at the Lux nightclub in South Yarra in November 2024 and an arson and shooting in Bundoora on the same night as the synagogue attack.

Two men had been arrested previously in relation to the Lux nightclub fire on 15 May 2025, with a police spokesperson indicating after the arrest, that the two men were not directly involved in the synagogue attack and that the arson attack at Lux nightclub was not a political attack.

The JCCT later charged three men with arson, conduct endangering life and theft of a motor vehicle with police alleging that they set fire to the synagogue. On 31 July 2025, the JCCT charged 21-year-old Giovanni Laulu from Werribee, on 21 August 2025, the JCCT charged 20-year-old Younes Ali Younes from Meadow Heights, and on 19 June 2026, the JCCT charged a 20-year-old man from Airport West. None of the three men were charged with terrorism offences.

Misinformation and conspiracy theories Following the attack, Antoun Issa, a former Guardian Australia journalist and chief of staff to Greens senator Mehreen Faruqi, made conspiratorial claims that the attack may have been a "false flag" perpetrated by Zionists. Issa was reportedly reprimanded for his comments and was counselled over the statement.Almost an epiphany on anti-Semitism for Anthony Albanese. The Australian. 11 December 2024. A similar conspiratorial statement blaming a Jewish conspiracy for the attack was made by Wissam Haddad (also known as Abu Ousayd), an Islamic preacher in Sydney who previously came under public scrutiny for antisemitic remarks.Wissam Haddad says attack on the synagogue was orchestrated to ‘draw public sympathy’ amid rising anti Semitism.

On 4 July 2025, an unknown perpetrator attempted to set East Melbourne Hebrew Congregation on fire by pouring a flammable liquid on the entrance and igniting it.

Iranian involvement

On 26 August 2025, Australian Prime Minister Anthony Albanese announced that ASIO determined Iran was allegedly involved in planning the attack. As a result, Iranian ambassador to Australia Ahmad Sadeghi was expelled from the country and Australia suspended operations of its embassy in Tehran. On 27 November 2025, Australia listed the Islamic Revolutionary Guard Corps (IRGC) as a "state sponsor of terrorism" under the Criminal Code Amendment (State Sponsors of Terrorism) Act 2025.
