The march on Sydney Harbour Bridge over the weekend has further fuelled political debate over Australia's position and response to ongoing humanitarian situation in war-ravaged Gaza.

Police "feared the worst" as about 90,000 people joined the pro-Palestine protest on the Sydney Harbour Bridge on Sunday, dwarfing the numbers that organisers had expected.Leaders say the situation turned "perilous" and there was the threat of a crowd crush at the last-minute rally.
