An extensive two-month journey circling the Land Down Under was terminated following the tragic passing of an older woman who was left behind by the vessel on a distant island.
Suzanne Rees had been walking on the remote island with shipmates from the Coral Adventurer, but broke off from the group for a pause. The vessel sailed away leaving her and went back after some time after the ship staff realised the woman was unaccounted for.
A large-scale search operation located her remains the following day.
Officials are investigating the incident, in coordination with police and the state coroner.
Chief Executive of the shipping company announced that guests and personnel on the vessel were notified that the continuation of the journey had been terminated due to the "unfortunate death and earlier mechanical issues".
Through an announcement, he added that travelers would be provided a total repayment, and said the organization was working "to organize the travel back of the individuals via specially arranged planes".
Regulatory bodies also published an updated announcement, and said they had "delivered a notice to the Commander" preventing any further travelers from getting on the ship.
The spokesperson said that they would inspect the liner in Cairns upon its coming back.
The vessel first departed Cairns on the 24th of October, and was just two days into the expedition at the moment of the senior passenger's death. The tropical location was the first stop on the journey.
Passengers on the vessel - who usually pay tens of thousands of dollars to participate in the cruise - were ferried there for a shore visit with the choice of hiking or underwater exploration.
The offspring of the victim said that her family was "stunned and grieved that the vessel left the island after an organised tour without my mother".
In her statement, she characterized her mum as an "energetic elderly person" who was a affiliate of a bushwalking club.
"Based on limited details we have been provided, it looks that there was a failure of responsibility and common sense," she said.
She further stated that she wished the inquiry would be able to pinpoint what "the company should have done that might have preserved Mum's life".
"We understand from the police that it was a exceptionally warm afternoon, and she fell ill on the mountain ascent," she stated.
"She was asked her to return, unescorted. Then the vessel left, apparently without doing a roll call.
"At some stage in that sequence, or not long after, mum died, alone."
Through an announcement, the CEO confirmed that the company was "cooperating fully with investigators to support their investigation".
He mentioned that the firm was "very regretful that this has happened" and had offered its full support to the loved ones.
The liner serves up to 120 passengers with forty-six staff, according to corporate information. It was specially constructed to access distant areas of the Australian coastline and is outfitted with "auxiliary vessels" - small boats used to take travelers on shore trips.
Incidents such as this are infrequent, and passenger vessels have protocols to record which individuals are getting on or getting off, according to maritime specialists.
"Leaving covertly or [back] on the ship simply isn't an option," an authority commented.
Shipping companies take these methods extremely carefully and have "sophisticated systems in place to stop such events from happening," the specialist added.
"This is presumably a shocking - and tragic - one-off."
