WASHINGTON — A high-end cruise from Australia has been called off after an 80-year-old traveler tragically died during a stopover. The passenger, Suzanne Rees, was discovered deceased on Lizard Island, which was one of the initial ports of call in the planned 60-day journey. This lavish adventure, reportedly costing $50,000, was meant to showcase the Australian coastline, culminating in Western Australia.

Mark Fifield, CEO of Coral Expeditions, the company operating the cruise, explained to the BBC that the trip had been terminated due to the “tragic passing of Suzanne Rees and prior mechanical problems.” He assured that all passengers would receive full refunds and that arrangements for their flights home were underway.

Rees was declared missing on Saturday night after the crew of the Coral Adventurer discovered she had not reboarded the vessel. A comprehensive search by land and sea was initiated, leading to the discovery of her body on the island the following day.

Rees was reported missing Saturday night after crew members aboard the Coral Adventurer confirmed she had not returned to the ship. A land and sea search was launched, and her body was discovered on the island on Sunday.

According to the Australian Broadcasting Company, Queensland police described her death as “sudden and non-suspicious.”

The Coral Adventurer had docked earlier Saturday at Lizard Island, a remote island 19 miles off Australia’s Queensland coast. According to the Coral Expeditions website, the island features a variety of excursions, including hiking, swimming and snorkeling.

According to the BBC, Rees had reportedly been hiking with fellow passengers on Saturday but is believed to have broken off from the group to rest.

Authorities are now investigating how Rees went unaccounted for when the vessel departed without her. The Australian Maritime Safety Authority told CNN it would be investigating the incident, including reviewing “the circumstances surrounding why the passenger may not have been accounted for during boarding.”

Rees had boarded the cruise just one day earlier. 

 Fifield told CNN the company was “deeply sorry” for the incident and has been in contact with the woman’s family. “We will continue to offer support to them through this difficult process,” he said.
