Oliver Peterson: Australian correspondent on the Disney cruise passenger being presumed dead after search called off - Heather du Plessis-Allan Drive

Search teams have been unable to find a man who went overboard on a Melbourne to Auckland Disney cruise. 

Reports claim a 73-year-old jumped from the Disney Wonder in the early hours of Saturday morning. 

The vessel turned back for about five hours to search alongside search efforts from the air. 

Australian correspondent Oliver Peterson says this will likely come as 'harrowing' news to the passengers and crew members on board.
