Hundreds of thousands march in Sydney to protest Israel's war on Gaza

Hundreds of thousands marched across Australia's iconic Sydney Harbour Bridge on Saturday to demand an end to Israel's war on Gaza.

The world-famous landmark was closed for the major pro-Palestine march after the Supreme Court of New South Wales refused an application by the police to ban the demonstration on the grounds that it risked a "crowd crush".

A spokesperson for the Palestine Action Group Sydney, which called the protest, put crowd estimates at 300,000.

Attendees included transparency activist Julian Assange, Bob Carr, Ed Husic, indigenous actor Meybe Wyatt and Greens senator Mehreen Faruqi.

Faruqi addressed the crowds before they set off, commending them for "defying Chris Minns" after the New South Wales premier said: "We cannot allow Sydney to descend into chaos."

"It was never about logistics. It was never about traffic. It was never about communications or anything else. It was always about stopping us and silencing us. It was always about protecting Israel and the Labor government from accountability," Faruqi said.
