Sydney and Port Botany have been closed to all shipping movements due to a super storm which hit the Australian coast.
The intense, low-pressure system formed off the New South Wales coast near Sydney and the Hunter district, with winds of up to 126kmph.
The conditions caused two vessels to collide in the Sydney port when the mooring lines of a 67,000t container vessel snapped. This collision led to the snapping of the mooring lines of a third vessel.
According to the report, a cold front is expected to reach the South Coast late Thursday and it will slowly move along the coast.
On Friday, a high-pressure system is expected to form over eastern NSW and will shift across the Tasman Sea on Saturday.
Officials have warned that wind gusts can be 40% stronger than the average speeds.
A weather report issued by the Bureau of Meteorology this morning said: "Cloud is wrapping around this low and is being pushed down towards New Zealand.
"Patchy cloud and isolated thunderstorms extend from the Pilbara region to a low-pressure system over the south-west of Western Australia.
"A cold front and an associated band of low cloud is crossing the south-eastern parts of South Australia, Victoria and also Tasmania."
