When bullets began flying at Sydney's Bondi Beach on Sunday, strangers Wayne and Jessica found themselves in the same nightmare scenario. They couldn't find their three-year-olds.

In the chaos, separately, they desperately scanned the green. People who'd gathered to celebrate the first day of Hanukkah screamed and ducked. Others ran. Some didn't make it far.

The 10-odd minutes that followed were the longest of their lives.

Wayne's body was acting as a human shield for his eldest daughter, but his mind was elsewhere: with his missing daughter Gigi.

"We had to wait all that time for the gunshots to stop. It felt like eternity," he tells the BBC.
