The seagulls are still flocking to Sydney's beaches but they are out of luck waiting for a hot chip to drop.

Bronte and Bondi beaches are closed after thousands flouted the government's ­social-distancing laws last weekend.

And, save for the odd jogger, limited to the pavements and paths because the beaches and pools are fenced off around these popular outdoor spots, there is no one around.

Picnic tables, BBQ areas and playgrounds - where families and tourists just days ago competed for space - are now deserted and the bustling cafes are empty.

Devoted swimmers who religiously crawl through their laps at Icebergs and Prince Alfred Park pools all year round have had to hang up their goggles as Sydneysiders pull together to stem the spread of COVID-19.

The city may not be in total lockdown yet but it is hard to believe this is a metropolis of more than 5 million people.

The normally bustling streets and wharves at Circular Quay, from the Rocks to Opera House, are deserted and the few drivers on even the busiest roads have the lanes to themselves. The normally-packed Cahill Expressway is almost empty.

The harbour is clear of ferries and boats with commuters curbed and business activity confined mostly to tasks which can be performed indoors.

"It's not quite a ghost town but it is the bare minimum (of people)," said photographer Toby Zerna who captured these striking drone images.

"And it is so quiet. I am noticing there is no plane noise, no choppers, the hum of the city is quieter.
