The twisted Bondi Beach terrorists who slaughtered 15 people in Australia’s worst mass shooting in decades had bombs and homemade ISIS flags stashed in their car, police revealed Tuesday.

The father-and-son suspects, Sajid and Naveed Akram, targeted the Jewish community celebrating Hanukkah on Sunday in “a terrorist attack inspired by Islamic State,” Australia’s federal police commissioner Krissy Barrett said.

Investigators found improvised explosive devices and at least two black ISIS flags in a car at the scene registered to the younger Akram.

Both men had traveled to areas in the Philippines where Islamic State-linked networks are known to operate just weeks before the massacre, police also confirmed.

The Philippines Bureau of Immigration confirmed the pair had been there from Nov. 1 to Nov. 28. However, it wasn’t immediately clear if they received training while there.

Still, the police commissioner stressed that “early indications point to a terrorist attack inspired by Islamic State, allegedly committed by a father and son.”

“These are the alleged actions of those who have aligned themselves with a terrorist organization, not a religion.”

Despite this — and the fact that the younger terrorist had previously been on the radar over links to known terrorists — Prime Minister Anthony Albanese downplayed the ties, claiming there was no evidence the killers were part of an organized terror cell.

“The clear advice that we have at this point is there’s no evidence of collusion, there’s no evidence that these people were part of a cell. Clearly, they were motivated by this extremist ideology,” Albanese told Australia’s ABC network.

“There may well be further information coming to light, but it would appear that these two have acted alone, driven though by this evil ideology.”

He confirmed the younger Akram had been probed by Australia’s spy agency, ASIO, in 2019 — but “was not on a watch list” when he unleashed the massacre with his dad.

“He was investigated because of his connections with two people who subsequently — both of whom went to jail. What ASIO do is they go through and interview anyone who is connected in any way, and they go through, including family members and others,” Albanese said.

“They determined that there was no evidence of this person planning or considering or indeed promoting any act of violence, or any act which could be deemed to be antisemitic, targeting the Jewish community, which is what occurred.”

The details emerged after the pair fired upon hundreds of people during a 10-minute killing spree at a Hanukkah celebration at the famed beach.

The elder Akram, 50, was fatally shot by police. His 24-year-old son was being treated at a hospital.

The massacre left 15 victims dead and dozens more injured.
