An extensive two-month journey through the Land Down Under is being halted days after the fatal incident of an senior lady who was stranded by the cruise liner on a distant island.
The elderly woman had been trekking on Lizard Island with fellow passengers from the cruise ship, but separated from the group for a rest. The liner departed without her and came back several hours later after the personnel realised the passenger was not present.
A major rescue mission located her person the subsequent day.
Officials are examining the tragedy, alongside police and the state coroner.
The CEO of the cruise operator stated that travelers and personnel on the ship were notified that the continuation of the voyage had been called off due to the "unfortunate death and previous engine troubles".
Via official communication, he added that travelers would be provided a total repayment, and said the company was working "to arrange the homeward trips of the individuals via chartered flights".
Officials also issued an revised communication, and said they had "delivered a notice to the Master" preventing any new passengers from getting on the liner.
The representative said that they would inspect the ship in the port city upon its return.
The vessel initially left Cairns on 24 October, and was only 48 hours into the voyage at the moment of the senior passenger's passing. Lizard Island was the opening port on the itinerary.
Guests on the ship - who generally pay substantial amounts of dollars to join the expedition - were taken there for a shore visit with the possibility of trekking or snorkelling.
The offspring of the elderly passenger said that her relatives was "shocked and distressed that the liner left the location after an scheduled outing without my parent".
In her statement, she described her mum as an "active elderly person" who was a participant of a bushwalking organization.
"From the little details we have been provided, it seems that there was a failure of attention and common sense," she said.
She further stated that she desired the investigation would be able to pinpoint what "the operator should have done that might have protected Mum's life".
"According to reports from the police that it was a very hot period, and she fell ill on the hill climb," she revealed.
"She was asked her to return, alone. Then the ship departed, apparently without performing a passenger count.
"At some stage in that sequence, or not long after, mum died, alone."
Via official communication, the Chief Executive verified that the operator was "cooperating fully with officials to support their investigation".
He said that the firm was "extremely apologetic that this has occurred" and had provided its complete assistance to the relatives.
The vessel serves up to one hundred twenty passengers with forty-six personnel, according to official information. It was specially constructed to enter distant regions of the nation's shoreline and is equipped with "tenders" - minor craft used to transport passengers on shore trips.
Events of this nature are uncommon, and passenger vessels have systems to track which travelers are embarking or disembarking, according to maritime specialists.
"Sneaking ashore or [back] on the ship really isn't an possibility," a specialist stated.
Vessel operators regard these procedures with great importance and have "sophisticated systems in place to prevent such events from happening," the authority continued.
"This appears to be most likely a shocking - and unfortunate - isolated incident."
