On April 3, 2014, 63-year-old Christine Armstrong, a seasoned swimmer and beloved member of the Tathra Surf Club, went for a routine ocean swim off the coast of New South Wales, Australia. Midway through the group’s 600-meter swim, she said she wasn’t feeling well and decided to head back alone—unaware of the danger nearby.

Moments later, other swimmers saw a fin in the water and birds diving above—a classic sign of a predator. Believing Christine had already reached shore safely, the group returned. But she never made it. The next day, her goggles, swim cap, and partial remains washed up, leading authorities to believe she was fatally attacked by a 13-foot shark, likely a great white.

Her husband, Rob, who had been swimming nearby, said she was taken so swiftly she wouldn’t have even realized what happened. The local surf club mourned her deeply, honoring her memory as a strong, joyful presence in the community and in the water.

Though the attack occurred over a decade ago, renewed attention through a resurfaced video has brought fresh waves of sympathy online. Christine’s story remains a chilling reminder of nature’s unpredictability—and the respect and caution the ocean demands.
