Christchurch Mosque Attack's Australian Roots Demand Full Reckoning
A police officer stands guard in front of the Al Noor mosque in Christchurch, New Zealand, where one of two mass shootings occurred during Friday prayers on 15 March 2019. The attack, perpetrated by an Australian terrorist, left 51 people dead and dozens injured. The photograph captures a moment of solemn vigilance at the site of one of New Zealand's deadliest terrorist incidents.
Persistent Presence in Australian Legal System
The Australian terrorist's propaganda continues to surface in the Australian legal system, particularly in cases involving young offenders. In 2025, a 14-year-old boy in South Australia was sentenced for possessing documents with information for terrorist acts and extremist material, including the shooter's manifesto on his devices. Two years earlier, a 16-year-old in South Australia received sentencing for several terrorism offences, with the judge noting his activities on Discord included sharing material from Islamic State and modern-day Nazi groups, along with images of the Christchurch killings.
Courts have heard about animated recreations of the Christchurch mosque shooting and police finding the attacker's video on storage devices. This growing legal record demonstrates the continued reach of the Christchurch attack within Australia, where the perpetrator originated.
Contrasting National Responses
While New Zealand has conducted a royal commission and continues with a coronial inquiry to confront what happened that day and ask what could have prevented it, Australia has seen little public accounting of what could have been done locally to identify the terrorist or stop the attack. This is despite the terrorist's known interactions with local far-right groups before the massacre.
In 2020, the terrorist pleaded guilty to 51 murders, 40 attempted murders, and engaging in a terrorist act, receiving life imprisonment without parole in New Zealand. Meanwhile, Australia has failed to conduct similar comprehensive examinations of the attack's origins within its borders.
Global Spread of Extremist Material
The terrorist's manifesto and the digital propaganda of his livestreamed attack on the Al Noor mosque and Linwood Islamic Centre remain pervasive internationally. In the United States, court records show continued circulation of this material. When Dallas Humber, one of the leaders of the white supremacist Terrorgram network, was charged in 2024 for soliciting hate crimes and the murder of federal officials, the indictment detailed how she helped create a publication celebrating white supremacist attackers as heroes.
Their so-called Saint Encyclopedia sat between two stills from the livestreamed massacre. Humber received a 30-year prison sentence, and Terrorgram has since been listed as a terrorist organisation in Australia.
Roots in Replacement Conspiracy Theories
Hank Teran, chief executive of Open Measures, an open-source threat intelligence and social media research platform, tracks the spread of such material. He suggests the terrorist's propaganda continues circulating because it was intentionally framed under the guise of the great replacement conspiracy theory, which claims there is a plot to take over white European countries with immigrants.
In the Christchurch context, that other was Muslims, Teran explained. The Poway synagogue shooting in California a few weeks after Christchurch targeted Jews, while the El Paso shooting in Texas targeted Latinx people. Teran emphasizes that public response cannot rely solely on content moderation, de-platforming, or age restrictions on social media.
Community Calls for Action
Rita Jabri Markwell, legal advisor to the Australian Muslim Advocacy Network, states that Australians care about what happened at Christchurch, but the country's leaders have failed to help remember it together. To grieve what happened together is crucial because it validates our shared humanity, she emphasizes.
The significance of the Christchurch terrorist's roots in Australia remains improperly recognized or addressed, Jabri Markwell adds, even as the Muslim community continues to be painted by politicians and others in positions of power as a group to fear or hate. He was socialized in his attitudes growing up in Australia, she notes. A lot of his online activity was in Australia. A lot of the hate that he developed happened in Australia.
Moving Beyond Words to Action
Alaa Elzokm OAM, imam of Elsedeaq Heidelberg mosque in Melbourne, will travel to Christchurch for a commemoration of the attack, speaking with Sakinah Community Trust led by widows, mothers and daughters who lost family members that Friday in 2019. Elzokm states that dealing with Islamophobia in Australia, as with all forms of racism, requires not only showing sympathy but taking firm action so everyone can feel safe when they worship.
We don't want the incident to be forgotten with time, he asserts. Words are no longer enough. The community demands concrete measures to address the underlying issues that contributed to the radicalization of an Australian citizen who committed such atrocities on foreign soil.
