Mourners in Australia fell silent on Sunday in honour of the victims of the Bondi Beach attack.
The memorial was part of a national day of reflection to mark a week since the shooting in which two gunmen opened fire on an event celebrating the Jewish festival of Hanukkah.
A 10-year-old girl, a British-born rabbi and a Holocaust survivor were among 15 people killed in the attack.
Prime Minister Anthony Albanese was booed when he arrived at the memorial event - an expression of anger by Australia's Jewish community against his government after a rise of antisemitic attacks over the past few months.
As the sun set over Sydney on Sunday evening, a minute's silence was observed at 18:47 (07:47 GMT) - exactly one week since the first reports of gunfire at the famous beach.
There was heavy security at the memorial event. Some cordoned-off areas were guarded by armed riot squad officers who had their faces covered, while a police patrol boat was visible off the coast of Bondi Beach.
For many Australians, this level of security is an unfamiliar sight.
A large crowd - many wearing kippas, the Jewish skullcap, or draped in Australian flags - gathered to listen to speeches after observing the silence.
Bee balloons floated in the wind in honour of the youngest victim of the attack, Matilda, who was nicknamed "Matilda Bee".
Later in the ceremony, the crowd sang Waltzing Matilda, the song the 10-year-old was named after.
Soon after, the crowd chanted the name of another child - Chaya, a 14-year-old who put herself in the firing line to protect a stranger's children.
Shot in the leg, she used crutches to take to the stage.
"If you guys get inspired by one thing, one thing on all this, be the light in that field of darkness," she said.
The event ended with the lighting of the menorah - something the crowds gathered for Hannukkah last week couldn't do.
But Sunday's memorial was not limited to Bondi Beach or the state of New South Wales.
In a nationwide gesture of "light over darkness", the windowsills of countless homes across Australia were lined with candles.
As Albanese arrived for the ceremony, one person in the crowd shouted: "Blood on your hands."
The prime minister looked startled at the hostility, and his wife Jodie Haydon grasped his arm in support.
At least one member of the crowd was tackled by police after moving towards the prime minister.
The Jewish community in Australia has repeatedly said this attack was a shock but not a surprise after a rise in antisemitic attacks in Australia since the 7 October 2023 Hamas attack on Israel, and the subsequent military retaliation war launched by Israel in the Gaza Strip.
The overwhelming view is that more could and should have been done to prevent the Sydney attack from happening.
Albanese has acknowledged the criticism, saying: "I accept my responsibility for the part in that as prime minister of Australia."
More widely, Albanese has been accused by some of siding with the Palestinians over supporting Israel.
The relationship worsened when he moved to recognise the state of Palestine earlier this year.
Israeli Prime Minister Benjamin Netanyahu has accused him - as well as the leaders of other countries that have recognised a Palestinian state - of rewarding Hamas.
After the Bondi Beach attack last Sunday, Netanyahu said Albanese's government "did nothing to stop the spread of antisemitism in Australia".
