The victims are being remembered tonight at a beachside vigil, with thousands gathering to reflect and a minute's silence at 6.47pm (AEDT).
A candle was lit by Michelle Goldman, chief executive of the NSW Jewish Board of Deputies, to start the poignant minute's silence exactly one week after the first gunshots rang out.

After the silence, the national anthem was performed by Australian Jewish musician Ben Adler.
As the sun set over the iconic beach, musicians performed an evocative piece of music. A montage of images showed the flowers left at the scene alongside tributes to the victims.
All 15 names of the innocent killed in the attack were listed on the screens at the vigil.
People in the crowd stood and listened to prayers, some in Hebrew and some in English.
NSW Jewish Board of Deputies president David Ossip thanked the crowd for being there "in solidarity with the NSW Jewish community".
As he welcomed political leaders by name, there were some boos from the crowd for Prime Minister Anthony Albanese.
For NSW Premier Chris Minns there was a standing ovation as Ossip highlighted that he had not missed a single funeral for the victims.
There was also similar applause for NSW Opposition Leader Kellie Sloane, who Ossip said had gone to Bondi Beach on the night of the attacks to help victims.
"That is bravery, that is courage," he said.
He said the families "of those who were so cruelly murdered at this place" were also present.
"Your courage and your resilience inspire us, and we are sending our love and our prayers to you at this time."
The crowd again stood and applauded for the father of Ahmed al Ahmed, the hero who disarmed one of the gunmen.
"Ahmed has asked me to pass on the following message to us all: 'the Lord is close to the broken hearted. Today I stand with you, my brothers and sisters'," he said.
Ossip said more needed to be done, and there was loud cheering as he said "it cannot be disputed that we need a royal commission, which goes beyond NSW, to get to the bottom of how this catastrophe took place".
"We feared and suspected that this moment was coming."
In a more just world, "we wouldn't be gathered here this evening", he said.
"We'd be at home with our loved ones having a barbecue or a swim, talking about the Ashes or out and about enjoying a summer's evening at a time of year which so many of us treasure, which is traditionally characterised by joy.
"In a more just world, small children wouldn't have had to say goodbye to their parents this week, wives had to say goodbye to their husbands or the parents of 10-year-old Matilda to their beloved daughter."
Governor-General Sam Mostyn, King Charles III's representative in Australia, said she joined all Australians in "rejecting antisemitism".
"You have always been a vital part of Australia's story of success and belonging," she said.
She thanked those involved in responding to the attack, from surf lifesavers and lifeguards to hospital staff and civilians.
She thanked them for returning to the place "which was ruptured with an act of terror, unspeakable barbarism, at exactly this time".
"We will always remember the names of the loved ones who died here, and those who fought with courage to save lives," she said.
Rabbi Moshe Kotlarsky said he was there to bring a message millions of Jewish people around the world: "We are here with you, we stand with you, we cry with you, we ache with you, and we bless you with comfort, with strength, with faith and with resilience," he said.
"One week ago, terror came to this place. Monsters, indoctrinated with hatred, taught not to build but to destroy," he said.
He said there were 50,000 people in the crowd.
He paid tribute to his friend Rabbi Eli Schlanger, who was killed in the attack, and said the memorial would be Schlanger's "dream".
"Thousands of Jews standing together as one, thousands of non-Jews showing up standing shoulder to shoulder."
Day of high emotion
It has already been a day of high emotion, with flags flying at half mast and a banner flown over Bondi showing love for the Jewish community.
Thousands gathered dressed in white for an event this afternoon outside Bondi Pavillion, organised by the National Council of Jewish Women.
The all-faiths event saw multiple figures from both sides of politics attend.
Governor-General Sam Mostyn said political affiliations did not matter on such a day.
"I'm speaking to you not only as your governor-general, but also as a mother, as a friend, as a woman," she said.
"We're here in white, in the spirit of light, we must take that forward."
Independent MP Monique Ryan and Shadow Communications Minister Melissa McIntosh were also in attendance.

The women who gathered laid flowers at the memorial on Bondi Beach.
Inflatable balloons of bees were also seen, in memory of Matilda, the 10-year-old girl who was killed in the shooting who was affectionately known as "Bee".
Friends and families of other victims also returned to Bondi to pay tribute to those who died.
This included members of the Randwick Rugby Club, who lost one of their members Peter Meagher.

"He was a huge part of our club and we don't want to talk much today," club president Brian O'Sullivan said.
"We've just come here to pay respects to all the victims and to lay down a couple of special memories for us."
A light plane was flown over the beach this afternoon with a banner bearing a message of support.
"From Aus for our Jewish Community", the message read, with a red heart.
Tonight, another powerful display of solidarity will take place at Bondi.
'A moment of pause'
At 6.47pm AEDT, exactly one week since the first shots rang out, people across the country and at Bondi are being urged to light a candle and observe a minute's silence.
TV and radio networks are also being asked to participate in the minute's silence.
"Sixty seconds carved out from the noise of daily life, dedicated to 15 Australians who should be with us today," Prime Minister Anthony Albanese said.
"It will be a moment of pause to reflect and affirm that hatred and violence will never define us as Australians."

The NSW government said it will support Jewish leaders to deliver a community memorial too.
The prime minister will be among those mourners at the beach.
"The National Day of Reflection will be observed on the final day of Chanukah, a time traditionally associated with light, faith and resilience, making the loss felt by the Jewish community even more profound," Albanese said.
"The Commonwealth and state government will also work closely with the Jewish community on arrangements for a National Day of Mourning to be held in the New Year.

"This will allow families the time and space to lay their loved ones to rest and to support those still recovering."
There will also be a strong police presence at the beach.
NSW Police Commissioner Mal Lanyon confirmed some police would be carrying long-arm guns.
"You will see more officers than usual," he said.
"While our priority is keeping the community safe, it is equally about helping people feel safe as they come together to grieve."
Campbell Parade will be closed in both directions between Queen Elizabeth Drive and Ramsgate Avenue until about 10pm.
There will be multiple community vigils held across the country at 6.47pm, including a candle-lighting ceremony at Parliament House in Canberra.
