One of two men suspected of carrying out Australia's deadliest mass shooting in three decades will be charged later on Wednesday, Prime Minister Anthony Albanese said, as the funerals of the Jewish victims of Sunday's attack began.

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.

New South Wales Police said emergency services were called to Campbell Parade, the road that runs along Bondi Beach, just before 7 p.m. local time, to reports of a shooting.

The victims of a mass shooting at Sydney's Bondi Beach range from a 10-year-old girl with a gentle soul to an 87-year-old Holocaust survivor.

Hundreds had gathered for an event at Bondi Beach called Chanukah by the Sea, which was celebrating the start of the Hanukkah Jewish festival.

At least 15 people were killed and dozens of others wounded on Sunday in a shooting at the beach, the police said.

England and Australia players will wear black armbands and flags at Adelaide Oval will be flown at half-staff on Wednesday in an Ashes tribute to the victims of the Bondi beach shootings.
