More than 100 firefighters are battling a blaze on a ship in Port Kembla Harbour, just south of Wollongong.

Flames broke out in the cargo hold of the bulk iron-ore carrier, prompting the evacuation of all crew members.

Fire crews have travelled from Sydney and the Illawarra to help tackle the inferno.

Environment Protection officers are there, and netting has been placed around the ship in case of diesel or oil spills.

Shipping operations at the port have been suspended.
