A seafarer is missing presumed dead after falling from a Japanese capesize off Australia.

The man was lost from the 177,000-dwt Spring Hydrangea (built 2006) off the Pilbara coast on Saturday morning.

No trace has been found of him, despite a search.

Australian media said the Shunzan Kaiun vessel was heading from Dampier to China when the alarm was raised 130 nautical miles from Dampier.
