Cyclone Ilsa has hit Western Australia as a category five storm, setting a wind speed record.
Severe Tropical Cyclone Ilsa struck the state close to Port Hedland, the world's largest iron ore export hub, just before midnight (17:00 BST).
However, it has so far spared populated areas from major damage.
The storm has been downgraded to category three, but a red alert remains in place for some inland communities.
The cyclone is the strongest to hit the region in some 14 years.
