Surfers and swimmers took to the water at Bondi Beach, and a minute's silence was held.
15 people were shot dead when two men opened fire on a Hanukkah celebration on Bondi Beach on Sunday.
Australian Prime Minister Anthony Albanese said Sunday, a week after the attack, had been declared a day of reflection to honor the victims. He urged people to observe a minute's silence.
"We are urging people around Australia to light a candle at 6:47 p.m. - exactly one week since the attack - as an act of silence to remember, with family, friends or loved ones," he said in a speech on Friday.
According to Albanese, the largest effort to buy back weapons will be carried out since 1996, when efforts were made after a shooting in Tasmania's Port Arthur where 35 people were killed.
"The horrific events in Bondi show that we need to get more firearms off our streets," he says.
The effort will see surplus, recently banned and illegal firearms repurchased, according to the Prime Minister.
