The pair of accused gunmen who carried out the lethal attack at a Hanukkah event on Bondi Beach, which claimed 15 lives, are believed to have been lone actors, as stated by national authorities.
Authorities also confirmed that Sajid Akram, 50, and his son Naveed Akram, 24, travelled to the Philippines on 1 November. Their travel plans included arriving in the capital Manila before traveling onward that same day to Davao City. The pair returned to Sydney on 29 November.
Investigators have stated the individuals did not undergo any type of attack-related coaching or "logistical preparation" during their stay in the Philippines. Initial findings from Philippine authorities indicate they "rarely left" their accommodation.
The shooting—described as Australia's most severe firearm massacre since 1996—has been formally classified as a act of terrorism.
"We are currently reviewing the footage," she said, noting that initial assessments suggest that "the alleged offenders are alleged to have operated independently."
National law enforcement Commissioner Krissy Barrett informed the press on Tuesday that security camera video tracking the alleged gunmen's whereabouts in the Philippines had been provided to domestic investigators.
"Our investigation shows little to no indication to support the idea these accused individuals were part of a wider organization, or were instructed by overseas entities to execute an attack," the police chief said.
Yet, the duo were additionally not necessarily in the Philippines as tourists, she clarified. She stressed that, given that the probe is still active, new evidence may emerge.
Previously, the nation's Prime Minister Anthony Albanese said it looks as though both alleged attackers were "inspired by ISIS" beliefs.
During the attack, Sajid Akram was killed by responding officers. He and his son Naveed—both armed with rifles—allegedly opened fire on attendees at the Hanukkah event.
Naveed Akram, who was hospitalised after the shooting, has been formally accused of 59 offences. These encompass 15 charges of murder and one count of committing a act of terrorism. He is scheduled to face court in April.
In the wake following the shooting, border authorities in the Philippines stated that the older suspect had arrived in the country using an Indian passport, while his younger suspect used an Australian passport.
The two had stated the southern city of Davao as their final destination. Their booked return flight to Australia was for Sydney.
Davao is a expansive city on the east of Mindanao, the Philippines' largest island in the south. Historically, Islamist militants have been known to operate in less developed parts of southern and western Mindanao.
