Here's what we know about the victims who have been named so far: Schlanger, 41, was assistant rabbi at Chabad Bondi, which put on the Chanukah by the Sea event targeted by the two gunmen. Chanukah is another transliteration of the Hebrew name of the holiday.
Schlanger was born in the United Kingdom but lived in Bondi near the scene of the shooting. He had recently become a father for the fifth time.
"Nothing was too big for him," said his friend Alex Ryvchin, the Co-CEO of the Executive Council of Australian Jewry addressing the media on Monday. "He was the sort of person who illuminated our lives with kindness, his grace and generosity."
At Hanukah in 2024, Schlager posted a video of himself smiling and dancing at night at the side of a road to the song "Just a Little Bit of Light."
The post is titled "Here's the best response to combat antisemitism."
Marika Pogany, originally from southern Slovakia, is being remembered for her charity work and as a long-term volunteer who delivered kosher meals on wheels.
The former Slovakian president Zuzana Caputova called 82-year-old Pogany a close friend.
The Australian city of Sydney was "a refuge" for the daughter of a Holocaust survivor, "far from the horrors of fascism and communism," Caputova wrote on Facebook.
"Apart from her mother and uncle, who returned from Auschwitz, all other members of this family did not survive the Holocaust."
Slovakia's President Peter Pellegrini also confirmed Pogany was among the victim's of what he called "this senseless, violent rampage."
Holocaust survivor and engineer Alex Kleytman was at Chanukah by the Sea with his wife, children and grandchildren.
His wife Larisa said he died trying to protect her from the bullets, according the Chabod Jewish organization.
As a child, Kleytman survived the Nazi Holocaust during World War II. The 87-year-old emigrated to Australia from Ukraine in the 1990s to escape antisemitism.
The youngest victim is ten-year-old Matilda, who died in hospital after being shot.
Just before the shooting, Matilda playing with animals at a petting zoo at Chanukah by the Sea, which she was attending with her family, including her sister, local media report.
Her aunt Lina Chernykh described the 10-year-old as "happy, bright" girl.
"She'd always kiss me, cuddle me and give me the energy … to be happy," her aunt said.
Peter Meagher was a retired police detective and a long-time volunteer at a Randwick Rugby Club.
He was working as a photographer at the Chanukah By the Sea event on Sunday, the club said in a statement.
Meagher was a " much loved figure and absolute legend in our club, with decades of voluntary involvement," the club said.
Meagher is the first non-Jewish victim to be identified.
French national Dan Elkayam was killed in the shootings, French President Emanuel Macron confirmed.
The 27-year-old engineer, who moved to Australia a year ago, played soccer with a local club and lived with his girlfriend in Sydney.
He had been celebrating Hanukkah, and he died trying to intervene between one of the shooters and a girl who later died from her injuries, Chabad reported.
Reuven Morrison fled the former Soviet Union in the 1970s to escape antisemitic persecution, according to his daughter, Sheina Gutnick.
He died trying to protect his community despite being unarmed during Sunday's attack, Gutnick said, naming her father as the man seen in footage hurling an object at the gunman disarmed by Ahmed al Ahmed.
He "managed to throw bricks at the terrorist," Gutnick said in an interview with CBS on Monday.
Morrison, who split his time between Sydney and Melbourne, was a businessman and philanthropist known for his kindness and generosity, according to Chabad.
A member of Bondi's Chabad Synagogue, Tibor Weitzen left the Soviet Union for Israel, then later emigrated to Australia. He was attending the Chanukah by the Sea with his wife and grandchildren.
The 78-year-old died after shielding his wife and another family friend from the gunfire, local media report.
Yaakov Levitan was a vital part of Sydney's Jewish infrastructure known for his kindness and tireless work in assisting others, Chabad said.
Originally from South Africa, the 39-year-old is survived by his wife and four children.
