A search is underway in the South Pacific after a passenger ferry carrying dozens of people sank between two islands in Vanuatu, an island nation east of Australia.

At least one person has died and more than 30 others remain missing, according to Vanuatu's Ministry of the Prime Minister. The MV Matui was traveling between the islands of Ambae and Santo when it sank Friday. It had 47 people on board.

Searchers rescued 15 survivors and recovered one body. Local authorities have now shifted their efforts toward the coastline as the hunt for the remaining passengers continues, as currents may have carried survivors to shore.

"Our hearts and prayers are with the families who have lost loved ones," the ministry stated. "To the survivors, we pray for your strength and recovery. To the families of those missing and those we have lost, please know that the nation stands with you in this time of grief."

Retired Coast Guard Capt. Aaron Davenport told Fox News Digital that survival chances depend on factors such as water temperature, injuries, and access to flotation devices. "They may be clinging to debris. But as the days go on, the chances of survival are less and less," he said, adding that lack of food and water, along with hypothermia, could reduce survival rates.

The ministry indicated that the tragedy likely resulted from ignored marine warnings about strong winds and the possibility that the vessel was overloaded. "The safety of life at sea must come first," the ministry said. "Ship owners must ensure their vessels are seaworthy, carry all required safety equipment and have proper communication systems on board. Ignoring strong marine warnings puts lives at risk."

The government has launched a full investigation into the sinking to establish the facts and prevent future tragedies. Iririki Island sits off Efate Island in Vanuatu.

Another ferry disaster occurred on August 30, when the Filo Jet catamaran capsized off northern Cyprus with 267 people aboard. Fourteen people died, and 14 remained missing, while 239 were brought ashore alive. That ferry began taking on water shortly after departing port.
