Model Sinead McNamara found dead in Greece on luxury superyacht

An Instagram model working on a Mexican billionaire’s luxury superyacht has died in unknown circumstances.

Australian Sinead McNamara, 20, had been working on the £108million boat as a member of crew for four months.

Police said the 20-year-old was found hanging on the rear deck of the Mayan Queen IV – owned by Mexican mining magnate Alberto Baillères – in Argostoli on the Greek island of Kefalonia.

Authorities told The Sunday Times initial evidence pointed to the possibility of suicide but an investigation into her mysterious death has been launched.

Local media reports Miss McNamara was discovered in a critical condition and died on the way to a hospital in Athens on Friday.

The Instagram star, who was originally from Port Macquarie and lived in Sydney, arrived in Greece in mid-June this year after travelling to Bali, Alaska and the Whitsundays.

Her brother, Jake, confirmed his sister’s death on Saturday.

“I have unfortunately received the worst news of my life, [Sinead] has passed away,” he posted to social media.

According to local media, billionaire Mr Bailleres left the yacht, which was anchored off the island of Kefalonia, on Tuesday – leaving Miss McNamara alone with the crew.

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

The Mayan Queen was scheduled to set sail today 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.

Australia’s Department of Foreign Affairs and Trade (DFAT) 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.

Family and friends revealed Miss McNamara, who has more than 14,000 Instagram followers, was “jet skiing around the most beautiful turquoise water in the Med” just days before her death.

In her last Instagram post four days ago, the 20-year-old wrote about jetskiing in Komitata, Greece.
