SYDNEY/SINGAPORE—The U.S. Marine Corps said on Saturday a search and rescue operation was underway for servicemembers involved in an aviation “mishap” off the east coast of Australia.

The incident involved an MV-22 Osprey tilt-rotor aircraft, the III Marine Expeditionary Force based in Okinawa, Japan, said on its Twitter account.

“Ship’s small boats and aircraft from the 31st Marine Expeditionary Unit and Bonhomme Richard Expeditionary Strike Group are conducting the search and rescue operations,” the tweet said. “We will provide more details as they become available.”

Australia’s defense minister said in a statement that no Australian Defence Force personnel were on board. The incident occurred off the coast of Shoalwater Bay, in the state of Queensland, the statement said.

A local newspaper, the Courier Mail, reported the aircraft had 26 personnel on board when the incident occurred, with 23 now accounted for, without citing sources.

Michael Augustus, a spokesman for Queensland Ambulance, said one person had been taken to Rockhampton hospital, but he gave no further details of the circumstances and no details of the person’s condition.

The defense minister, Marise Payne, said she had briefed the U.S. defense secretary and the Australian prime minister.

More than 33,000 U.S. and Australian military personnel, including the Bonhomme Richard Expeditionary Strike Force, participated in the recent Talisman Saber joint military exercise in Australia which ended on July 25, according to a statement from the U.S. Army Public Affairs Office.

The exercise included participation from MV-22 Osprey practicing the deployment of U.S. Marine Corps reconnaissance teams.

Australia is a military ally of the United States.
