In the days before Christmas 2016, Victoria Police and the Australian Federal Police announced they had disrupted a plot to carry out a mass-casualty attack in Melbourne’s CBD on Christmas Day. The alleged plan centred on Federation Square and the surrounding precinct, and was to involve improvised explosives and the use of bladed weapons or firearms. A series of raids led to arrests. The men at the centre of the plot were later convicted of terrorism offences and sentenced to lengthy prison terms.
Our newsroom has reviewed the public record on the 2016 Christmas Day plot: the statements made by Victoria Police and the AFP at the time, contemporaneous mainstream reporting, and the outcomes of the Supreme Court proceedings that followed. Where allegations were later tested at trial, we describe the verified outcomes rather than restating untested claims as fact.
Overview: the plot and the raids #
On 22 December 2016, the Victorian Joint Counter Terrorism Team carried out overnight raids at addresses across Melbourne’s north. Several people were arrested. Police said the alleged plan was to detonate improvised explosive devices in and around Federation Square on Christmas Day, when the precinct — a short walk from Flinders Street Station and St Paul’s Cathedral — would be crowded, and that bladed weapons or firearms may also have been intended. Senior officers stressed that the threat had been disrupted and that there was no ongoing danger to the public arising from the alleged plan.
How a disruption operation works #
Counter-terrorism investigations in Australia typically run for weeks or months before any arrest. Agencies gather intelligence, monitor communications and movements, and make a judgement about when the risk requires intervention. Move too early and a case can collapse before there is enough evidence; move too late and an attack may not be stopped. The decision to act is one of the most consequential a joint team makes, and it is taken at a senior level. In this case, the team moved in the final days before the intended date.
Court outcomes #
The prosecutions ran through the Supreme Court of Victoria over an extended period. Several men were charged with conspiring to do acts in preparation for, or planning, a terrorist act.
One man, identified in the proceedings as a central figure, pleaded guilty to his role and was sentenced to 24 years’ imprisonment with a non-parole period of 20 years. He gave evidence in the prosecution of the others.
Three further men were found guilty by a jury. The youngest was sentenced to 22 years’ imprisonment with a 16-year non-parole period. Two others were each sentenced to 26 years for the plot. Those two had also been convicted over a related arson attack on a Shia mosque — the Imam Ali Islamic Centre at Fawkner — and their sentences were made cumulative, producing a total effective sentence of 38 years with a single non-parole period of 28 years and six months.
Those are among the longest terrorism sentences handed down in Victoria. They reflect the seriousness with which the courts treat conspiracies aimed at mass casualties, even where no attack is carried out — because the offence is the planning and preparation itself, not only a completed act. How serious criminal matters move from charge to verdict is set out in our explainer on the Victorian criminal trial process.
In context: Melbourne’s run of attacks #
The 2016 plot was the first in a cluster of events that struck the same part of the city. It was followed by the December 2017 attack at Flinders Street and the November 2018 Bourke Street attack. Federation Square, the steps of Flinders Street Station and the cathedral precinct are exactly the kind of open, symbolic, heavily-trafficked spaces that are difficult to protect without changing the character of the city.
The aftermath and what changed #
The response has been incremental: bollards, revised event planning, a heavier visible police presence at major gatherings, and closer coordination between agencies on public order in the CBD. None of it removes risk entirely. What the 2016 case shows is that the most effective protection often happens long before any public-facing security measure — in the intelligence work that detects and disrupts a plan before it reaches the street. A single agency rarely has the full picture; the pooling of state and federal capability is what allowed this plan to be stopped before Christmas morning rather than mourned after it.
