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.
The documents 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. This was revoked on Monday and the documents were published with some redactions.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 - is described as showing the men sitting in front of an image of an Islamic State group (IS) flag, making statements about their motivations for the attack.
The documents note that these include two single-barrel shotguns, a Beretta rifle, four improvised explosive devices (IEDs), and two IS flags.
In light of this attack, Australian Prime Minister Anthony Albanese faces mounting pressure regarding his government's response to antisemitic threats and questions about the security measures in place leading up to the incident. The community is calling for tougher gun control laws and a thorough investigation into links the attackers had with known extremist networks.
