On Wednesday December 12, 2012, 38-year-old Cassandra Scott lost consciousness in the surf at Coogee Beach. There was no sign of a pulse, her body was already a deep shade of blue – she was to all intents and purposes dead.

By chance, three strangers – a man swimming nearby, a local lifeguard and an off-duty emergency doctor – were in the right place, at the right time. With their combined efforts and training, they were able to make swift, informed decisions to resuscitate Cassandra and save her life.

This is the story of how the lives of everyone involved were changed forever.

This is a story that needs to be told more often.
