Aussie model’s cryptic post before mysterious death on billionaire’s superyacht in Greece

GREEK police are today set to reveal tragic new details about the sudden death of an Aussie model on a billionaire’s yacht.

UPDATE: Greek port authorities are today expected to reveal the preliminary findings of a post mortem examination into the death of an Australian model on a superyacht.

Sinead McNamara, 20, was found unconscious on the luxury US$140m Mayan Queen IV off the island of Kefalonia four days ago. She reportedly died while being flown to hospital.

Investigators told The Sunday Times a crew member found Ms McNamara on the rear deck of the vessel.

The 20-cabin, 92-metre yacht is owned by Mexican mining magnate Alberto Baillères, who is worth an estimated AU$9.6 billion.

“By the looks of it, she took her (own) life,” a source described as a senior official told the paper.

Ms McNamara, a Sydney-based Instagram influencer, had been working on the Mayan Queen IV for the past four months before her sudden death in the early hours of Friday morning.

The tragedy came as her mother Kylie and sister Lauren were making their way to Greece to join Ms McNamara for a holiday. They were reportedly told the news while in transit.

The young model had been looking foward to their visit, posting an upbeat message on social media just days before her death.

“Happy birthday to the most amazing big sister I could ever ask for, 5 days till I get to see you!!! Excitement is an ­understatement”, she wrote.

That post was in stark contrast to an earlier, cryptic message that appeared on Ms McNamara’s Instagram page.

“My head is all over the shop today,” she wrote, along with emojis of a volcano, a tornado and a needle with blood dripping from it.

Sharing an image of herself on a quad bike, she added: “Take me back to this where my only worry was not cracking my skull open.”

According to local media, Mr Bailleres left the yacht, which was anchored off the island of Kefalonia, on Tuesday — leaving Ms McNamara alone with the crew. Her body was reportedly found on the back of the boat two days later.

What happened in the 48 hours after the billionaire’s departure, in the lead up to Ms McNamara’s death, is now the subject of an inquiry by local authorities.

“The Coast Guard of Kefalonia has ordered an investigation into the circumstances that led to the death of the 20-year-old Australian national as well as an autopsy-necropsy,” In Kefalonia reported.

The Mayan Queen IV was scheduled to set sail (yesterday) but has been ordered to remain docked in the port of Argostoli until detectives have interviewed all crew members and a forensic examination of the vessel.

In a tragic development, local reports suggest desperate attempts were made to revive Ms McNamara at the scene before she died on route to hospital.

“Local port authorities were informed at 2am Friday morning that the body of the woman was found … at the back of the yacht,” Kefalonian Mantata said.

The paper said officers from the port authority, crew members and a doctor “tried for long time to bring her back” before rushing her to a hospital in Argostoli.

Doctors made the decision to fly her to a private hospital in Athens but Ms McNamara died during the helicopter flight, local media said.

The Department of Foreign Affairs and Trade said it has offered support to the McNamara family.

“DFAT is providing consular assistance to the family of an Australian who died in Greece,” a

spokeswoman said.

She was travelling in the seaside town of Pylos on the southwest coast of Greece.

In her last Instagram post four days ago, Ms McNamara wrote about jetskiing in Komitata, Greece.

Ms McNamara had been working on yachts while travelling in Europe.

There has been an outpouring of grief of Ms McNamara’s Instagram profile, from fans of her travel and modelling photography.
