Here’s the moment it hit Sydney Harbour. These photos were taken via the Sydney Harbour Foreshore Authority Live Stream between 11.10 and 11.20am.

You can see the storm clouds approaching.

As they invade the sky the city gets darker

And darker.

When it hits it’s almost a black out with rain and wind.

It’s even too much to the camera, covered with rain drops.

The damage at Kurnell is also becoming apparent. This tweet from Engadine Royal Fire Brigade shows the effect of the destructive winds.

There are also reports that the Sydney Desalination Plant, which is in Kurnell, is being evacuated after significant damage.

And the Huffington Post has photos of a flipped truck.

Flights appear to be grounded at Sydney Airport, and incoming planes skirt the city, waiting for the storm to pass.

Virgin Australia is one of the many airlines experiencing delays.

Qantas also has delayed some flights until the storm clears up.

Gridlocked traffic in the direction of the departures terminal is so bad people are even abandoning their cars to walk to their flights.

Claire Milet told The Guardian that they almost missed take off until she showed the airline the photo below.

“Apparently there were 30 people on our flight alone who missed it. Disgraceful for an international airport,” she said.
