The daughter of 80-year-old Suzanne Rees has shared the final message her mother sent just hours before she died — words that now feel especially heartbreaking in hindsight.

The Coral Adventurer, operated by Coral Expeditions, departed Cairns in Far North Queensland on October 24, 2025, for a planned 60-day journey around Australia.

Among those on board was 80-year-old Suzanne Rees, whose dream trip would soon end in tragedy.

Early in the journey, passengers stopped at Lizard Island, in the Great Barrier Reef, for an organized hike. That morning, everything seemed perfectly normal.

“She sent me a text that morning with a photo of the deck, saying: ‘Arrived at Lizard Island, going for a hike, and then afternoon swim,’” her daughter Katherine recalled in a new interview with 60 Minutes.

“We had no reason to think that this wouldn’t be the most amazing experience. We had no reason to think anything bad would happen.”

”The most horrible ways to die”

But during the hike, Rees reportedly became unwell. According to her family, she was told to make her way back down alone. She never returned to the ship.

It later emerged that the vessel left the island without realizing Suzanne was missing. A headcount wasn’t carried out until hours later, and by the time the alarm was raised and the ship turned back, it was already too late.

Concern only grew when Rees failed to show up for dinner aboard the Coral Adventurer, prompting a search of the ship. At first, crew members feared she may have gone overboard. Then, a search and rescue operation began, and the Coral Adventurer turned back towards Lizard Island.

Suzanne’s body was found the following day.

Katherine has since accused the cruise operator of serious failures, describing what happened as a breakdown in basic care.

“From the little we have been told, it seems that there was a failure of care and common sense,” she said. “We understand… Mum fell ill on the hill climb. She was asked to head down, unescorted.

“Then the ship left, apparently without doing a passenger count… Mum died, alone.”

”It would be one of the most horrible ways to die. And that does haunt me.”

Paid $30,000 for the trip

Suzanne reportedly paid around $30,000 for a luxury cruise around Australia, a journey intended to be a once-in-a-lifetime experience.

Instead, it ended in tragedy for the 80-year-old Sydney gardener, leaving her family devastated and insisting the outcome should never have happened.

An experienced bushwalking club member and former accountant, she had undergone a medical check-up before the trip and was given a clean bill of health.

Her daughter Kate said the situation should have been handled differently from the start.

“My mum was capable. She walked all the time. And I think what should have happened if it was the conditions were unacceptable, the walk should have been cancelled in the first place,” Kate said.

“Somebody needed to make that decision and say, ‘too hot, we’re not doing a walk.’”

In a statement, the cruise company said it was “deeply sorry” and acknowledged that some safety procedures “were not adequately implemented” on the day of her death.

For Katherine, though, it’s her mother’s final message that lingers most, a simple, hopeful note about a hike and a swim, sent before everything changed.
