Australia has changed in the past 24 hours, after a shocking act of terrorism targeted at the Jewish community left 15 people dead on Sydney's Bondi Beach.

The attack happened during a community event to mark the first day of Hanukkah on Sunday, with a 10-year-old girl, two rabbis and a holocaust survivor among those who were killed.

Amid the devastating pain there have also been stories of heroism, with blood banks inundated with volunteers and that incredible video of Ahmed al Ahmed wrestling the gun from one of the shooters.

In this special episode of hack, we head to Bondi Beach.

We speak with witnesses, members of Sydney's Jewish community and politicians, and ask how this unspeakable crime happened and how the nation can come to terms with its pain.
