Demonstrations have taken place in Australian cities against tight restrictions imposed to tackle a rise in Covid cases.

Thousands gathered in Sydney, with smaller protests held in Melbourne and Brisbane.

People chanted "freedom" as they marched through the center of Sydney. Officers made several arrests.

Australian governments have re-imposed lockdowns across the country amid a surge in new infections.

The arrival of the highly contagious Delta variant has challenged the country's previous strategy of border closures, quarantine programs, and snap lockdowns which helped keep cases low.
