Labor has proposed a public school funding boost – states, crossbenchers and the Greens want more. What happens now?

A coalition of cross-benchers have joined Australia’s largest states to push the commonwealth to invest more in public schools, escalating a standoff that risks derailing the next funding agreement.

Independent senators David Pocock, Fatima Payman and Jacqui Lambie teamed with the Greens on Monday to back calls from five states for the commonwealth share towards public schools to rise by 5% to 25%, a figure they say is necessary to finally reach 100% public funding.
