An Australian man is dead after falling from a cruise ship off the coast of the United States.
The man, reported to be businessman Jonathan Pfahl, went overboard on Wednesday as the Royal Caribbean ship headed to the Virgin Islands.
"Upon the initial report that an Australian adult male had gone overboard, our ship immediately turned, launched a rescue boat, and conducted a full-scale search," Royal Caribbean said in a statement.
"We are working closely with authorities and will continue to assist in their investigation."
The cruise company added "our hearts go out to the family and loved ones for their loss, and our care team is providing support and assistance during this difficult time."
Mr Pfahl lived in Sydney but was most recently based in London.
"We are all saddened to hear about the loss of Jon Pfahl - Jonathan spoke on our stage in London, his enthusiasm to make a difference and take people on a journey was infectious. We will all miss him RIP Jon," UK community organisation Yes Group posted to Facebook.
The Department of Foreign Affairs and Trade said it "stands ready to provide assistance, in accordance with the Consular Services Charter, should it be requested".
