Couple Abandoned in Shark-Infested Seas — Their Final Diary Entries Are Haunting
In 1998, a scuba trip on Australia’s Great Barrier Reef turned into one of the most chilling maritime mysteries in modern history. Tom and Eileen Lonergan, a young American couple, were mistakenly left behind in shark-filled waters — a tragedy that would later inspire the film Open Water and spark endless speculation about what really happened.
Their bodies were never recovered, but their journals — found later in a hostel room — offered a disturbing glimpse into their state of mind in the weeks before their disappearance.
A Day at the Reef That Turned Fatal
Tom, 33, and Eileen, 28, had just finished two years of Peace Corps service in Fiji and were traveling through the South Pacific. On January 25, 1998, they joined a dive excursion at St. Crispin’s Reef, an area nicknamed “Fish City” because of its teeming marine life.
Local fisherman Mick Bird recalled that shark activity in the area was unusually intense that day. “We couldn’t drop a line without pulling up a shark,” he later told reporters. “They ought to call that place Shark City.”
During their third dive, British diver Bryan Brogdan remembered seeing the couple marveling at a giant clam embedded in the reef, lit up by beams of sunlight from above. Brogdan eventually surfaced and returned to the boat — but Tom and Eileen remained below. He would be the last person to see them alive.
A Deadly Miscount
By mid-afternoon, the dive boat crew conducted a headcount before leaving the site. Confusion arose when two passengers briefly re-entered the water to take photographs. Crew member George Pyrohiw counted 24 heads, but skipper Geoffrey “Jack” Nairn was told there should be 26.
Instead of recounting, Nairn reportedly replied, “And two in the water makes 26.” The mistake sealed the couple’s fate.
When the vessel returned to Port Douglas, two dive bags remained untouched on deck. Inside were identification documents, personal belongings — and the shirt Tom had worn that day. Yet no alarm was raised. Even missing tanks and weight belts went unreported.
As darkness fell, the Lonergans drifted alone in the vast Coral Sea.
Too Late to Save Them
It wasn’t until two days later, after the boat had completed additional dive trips with new tourists, that the skipper finally inspected the abandoned bags. Realizing something was terribly wrong, he alerted authorities.
A massive rescue mission swung into action: Navy planes, helicopters, and civilian boats scoured hundreds of miles of open ocean. But despite the scale of the search, there was no trace of Tom or Eileen.
Over the following weeks, grim pieces of evidence began to appear:
-
Tom’s buoyancy compensator, labeled with his name, floating 50 miles north.
-
A wetsuit believed to be Eileen’s, shredded at the seat in a way consistent with a shark bite.
-
Additional dive gear, scattered along the Queensland coast.
Their bodies were never found.
Disturbing Diary Entries
What truly shocked investigators were the diaries found back at their hostel.
Tom had written, months earlier:
“I feel as though my life is complete and I’m ready to die. From here, my life can only get worse. It has peaked and it’s all downhill from here until my funeral.”
Eileen’s more recent entry was even more unsettling. Just 16 days before the dive, she confessed:
“Tom hopes to die a quick and fairly painless death. Tom’s not suicidal, but he has a death wish that could lead him to what he desires — and I could get caught in that.”
These writings fueled speculation that the couple may have accepted — or even embraced — their fate.
Mystery Without Closure
Some theories suggested the Lonergans staged their disappearance to begin a new life elsewhere. But those ideas crumbled under scrutiny: their bank accounts were never touched, their insurance never claimed, and no credible sightings were reported.
Everything pointed back to the same conclusion — a catastrophic accident at sea.
To this day, the Lonergans’ disappearance remains one of the Great Barrier Reef’s darkest stories, a haunting reminder of the dangers of the deep and the devastating cost of human error.
