A Darwin shipping company has been fined $190,000 after the death of a deckhand who lost his grip and drowned in January 2017.

The company’s workplace practices posed an “obvious risk to death” according to the judge after it was found that workers were required to jump across a gap onto a tyre, before pulling themselves up by chains to get access to the wharf.

Outside court, the victim's partner said the Northern Territory should follow Queensland’s lead and introduce an industrial manslaughter offense.
