Transport for NSW has urged mariners to take care after a shipping container was spotted off Glasshouse Rocks, Narooma today, June 8.
The container was spotted between Montague Island and the mainland, near Narooma. It is understood the container was one of many lost overboard from the APL England, south of Sydney.
A NSW Maritime Boating Safety Officer sighted the container floating below the surface, visible for a short period between waves, a Transport for NSW spokesperson says.
"It is believed to be one of 26 the empty refrigeration containers and is therefore buoyant due to the insulation material," the spokesperson said.
"It was a chance sighting and, despite looking for a further 45 minutes, it could not be found again.
"Tracking the container is extremely difficult given it is below the surface."
NSW Maritime has increased radio broadcasts through Marine Rescue advising mariners to navigate with caution as "the container is floating just under the water's surface and very hard to see".
"It is possible the container will come shore over the next 24 hours further south along the coast," the spokesperson said.
Last week, it was reported that 16 of the APL England's shipping containers have been recovered, with many still missing after the May 24 incident.
