I think it's also the role of councillors to be a voice for their communities and to lobby higher levels of government, especially when state and federal governments have failed to take any practical action.

There's a list of action pledges on that website that the campaign is asking candidates to respond to, which contain some details and reasons:

CEASEFIRE ADVOCACY - To support an immediate and permanent ceasefire in Gaza/Palestine, and advocate for all levels of government to apply pressure on Israel to achieve this.

INTERNATIONAL LAW & OBLIGATIONS - To support the United Nations, the International Court of Justice (ICJ), and the International Criminal Court (ICC), and to agree that, under international law and our obligations to prevent genocide, we should not send weapons to a state plausibly committing genocide, and to vote in support of a weapons embargo to Israel should you get the opportunity.

CEASEFIRE MOTION - To call for an immediate and permanent ceasefire in Gaza (Palestine), including through a council motion to prevent further loss of life.

DIVESTMENT FROM APARTHEID ISRAEL - To support a motion and vote for full disclosure and divestment of Council's financial ties to Israel in the context of its illegal occupation and apartheid, and military assault on Gaza.

SUPPORT FOR PALESTINIAN REFUGEES - To support and vote for motions that concern the provision of Council funds, resources and programs to assist Palestinians in our community who have been forced from their homelands (for example counseling, housing, food relief, English language classes, and cultural immersion support).

SISTER CITY RELATIONSHIPS - To create sister city relationships with Gaza, including through forming symbolic and practical links with civic organisations that are helping to rebuild Gaza's infrastructure and society.
