Christine, a long-time member of the Tathra Surf Club, was known for her strength and dedication in the water. That day, however, she reportedly told the group she wasn’t feeling well and decided to head back alone after covering about 200 metres, The Mirror reports.

Moments later, other swimmers spotted a fin in the water. Birds began circling and diving above the surface, a classic sign that a predator could be nearby. The group made a quick decision to return to shore, assuming Christine had safely beaten them back. She hadn’t.

“The shark was such a size”

The following day, Christine’s goggles, swim cap, and some remains were found washed up on the beach. Her body was never recovered
