Numerous powerlines and other trees were downed or uprooted in the storm, and people were being told not to travel.
Apartment roofs were also ripped off, with cars damaged and debris littering streets.
An air conditioning duct was ripped from a building in Dee Why and blown across the street, though miraculously nobody was hurt.
More than 400 calls have been made to the SES so far, with that number expected to rise.
This morning, 25,000 people are still without power, and it's expected that will remain the case for some time.
Firefighters said wild winds ripped the roof off a Forestville shopping centre, tore sheets of metal from apartment buildings and triggered a partial building collapse in Curl Curl.

The service described the incident as a "mini-cyclone", saying trees were knocked onto vehicles and roads, with powerlines torn down from Dee Why to Narrabeen.
"People were running. People were ducking. No-one knew where to go because there was no shelter," one resident said.
"It didn't matter where you drove it was still going bang, bang, bang on the roof."
The clean-up is ongoing this morning.
