Melbourne protesters have joined an international "day of rage" against Israeli airstrikes on Gaza, chanting "shame Abbott shame" and calling on the federal government to condemn the bombings.

The protesters rallied outside the State Library before marching to the Melbourne offices of the Department of Foreign Affairs and Trade on Lonsdale Street.

There they taped the names of Palestinians killed in Gaza onto the front doors and windows of the building, as speakers demanded the federal government speak out against Israel.

Police estimated a crowd of more than 500 people, some with their hands painted red and others holding placards calling for a boycott of Israel.
