South Australia's agreement for new school funding system is another brick in the wall protecting public schools from a Tony Abbott repeal, says Australian Greens spokesperson on Schools Senator Penny Wright.
"Each state that signs up makes it much harder for any Abbott government to unwind the Gonski model and rip money out of schools," Senator Wright said.
"Today's agreement between the Prime Minister and South Australian Premier is great news for all SA students and teachers.
"Mr Abbott's promise to attempt to repeal Gonski shows he can't be trusted to care about every child's education
"The Australian Greens know public schooling has been chronically underfunded for decades and we would use our numbers in the Senate block any attempt to move Australian students to a less equitable funding system."
