Australia will introduce wide-ranging reforms to crack down on hate speech, Prime Minister Anthony Albanese said on Thursday, days after the country's worst mass shooting in nearly three decades at a Jewish holiday event.

A Holocaust survivor, a 10-year-old and a Chabad rabbi were among the 15 people killed when two gunmen opened fire on a Hanukkah event at Australia's Bondi Beach on Sunday. Hundreds of people had gathered to mark the first day of the Jewish festival before the attackers struck at the event in Sydney.
