Members of the Irish Jewish community have attended an event in Herzog Park in Dublin to mark the second day of Hanukkah.
Organised prior to the shootings in Bondi, the event was attended by the granddaughter of Chaim Herzog, after whom the park is named.
Minister for Justice Jim O'Callaghan attended on behalf of the Government.
Chief Rabbi of Ireland Yoni Wieder said people were apprehensive about attending this evening's event.
Speaking on RTÉ's Six One News, he said if people cannot attend a celebration and commemorate festivals without "worrying for our lives" then the world is a "darker and dangerous place for all of us".
Rabbi Wieder said that he told his community they needed to make an extra effort to come out and be seen.
He said the Irish Jewish community are "proud and we are not going to cower".
"The terrorist that carried out this attack yesterday they want Jews in Sydney and around the world to live in fear, and our response is absolutely clear - we are here, we are going to continue to thrive," he said.
Rabbi Wieder said Hanukkah was about "lighting the light and sharing that light with the people around us", which is what they continued to do.
Jewish people need to be seen - Chief Rabbi of Ireland
He described the attack in Bondi as "absolutely sickening", adding it was a "barbaric, heinous act of terrorism" against the Jewish community as well as an "attack against our very values that underpin us as a civilised moral society".
Rabbi Wieder said he had spoken with Garda Commissioner Justin Kelly yesterday, and the priorities were very clear.
"It is not just about security at an event itself, it is about intelligence, making sure that any threats are known about in advance so that they can be thwarted," he said.
"It is about prosecuting people who have insighted violence who have made threats against the Jewish community or any other minority community."
Rabbi Wieder added it was not just about policing but looking at the "root problem".
"There is unfortunately a hatred against Jewish people that is spreading across parts of Western society and, unfortunately, parts of Irish society as well," he said.
He said the questions must be asked why is that happening, and who are the people who might single out a Jewish event or person for an attack, and what are we doing to ensure there is no space for that type of hatred in our society.
