A Yang Ming containership has lost 83 forty-foot containers in treacherous seas off Australia.

NT News reported that the 4,250-teu YM Efficiency (built 2009) was caught in large swells en route from Kaohsiung in Taiwan to Sydney's Port Botany on Thursday night.

It lost the boxes off Newcastle, while a further 30 containers on board were severely damaged.

A Yang Ming spokeswoman confirmed to AAP there were no dangerous goods or marine contaminants inside the containers.
