The suspected gunmen in the Bondi Beach attack threw explosives at the start of the deadly incident and had practised shooting weeks before, according to new court documents.
They allege the pair 'meticulously' planned the attack for months and, two days prior to the shooting, visited Bondi for reconnaissance.
Fifteen people were killed and dozens more injured when two gunmen opened fire on a Hanukkah celebration on 14 December. Explosives, including a 'tennis ball bomb', failed to detonate, the documents said.
Naveed Akram, 24, has been charged with 59 offences, including 15 counts of murder and one of terror. A second gunman - his father, Sajid Akram - was shot dead by police at the scene.
Last week, a temporary suppression order was made on the release of the police fact sheet to protect the identities of the survivors. It was revoked on Monday and the documents were published with some redactions.
Included in the new court documents are the details of several videos tracing the movements of the alleged gunmen in the months, days and hours before the attack.
One video, taken on one of their mobile phones in October, shows the men sitting in front of an image of an Islamic State group (IS) flag, making statements about their motivations and condemning 'the acts of Zionists'.
CCTV footage from the evening of 12 December captures the accused and his father in their car near Bondi Beach, resulting in accusations of premeditated planning.
The attack has raised significant concerns about intelligence handling regarding the suspects. Naveed Akram had previously been investigated for ties to a Sydney-based IS terrorism cell, casting doubt on why he and his father were permitted to procure firearms and travel prior to the incident.
As Australia mourns the victims of the Bondi attack, calls for a Royal Commission into the matter grow, alongside demands for stricter gun control measures amid a surge in antisemitic violence.
