Firefighters at a NSW port have worked "tirelessly" through the night to extinguish a blaze on board a Canadian-owned freight ship.
A Canadian ship docked on the NSW south coast is still burning as firefighters work "tirelessly" to extinguish the final flames more than a day after the iron-ore carrier caught fire.
All crew on board the Iron Chieftain escaped unharmed when the fire ignited in the cargo hold as dolomite was being unloaded on a conveyor belt at Port Kembla Harbour on Monday morning.
"Firefighters worked tirelessly throughout the night," Fire & Rescue NSW said in a statement on Tuesday.
The fire on the outer deck was extinguished on Monday, but efforts have since turned to sections in the cargo hold where an active fire still burns.
"Firefighters continue to attack this fire through hatches on the deck and hose lines have been repositioned," Fire & Rescue NSW said.
The fire is being monitored with a laser thermometer and is expected to continue throughout Tuesday with about 80 firefighters on hand.
