As education became a key election issue Abbott said that the Coalition and Labor were running a "unity ticket" and that the Gonski reforms would continue if he won office.
His then-education spokesman, Christopher Pyne, who now holds the portfolio, said that "every single school would receive, dollar for dollar, the same funding", whoever won.
Pyne is now leading the Government backflip, refusing to recognise the deals made between Labor and the states and describing the reforms as a "shambles" that needed to be replaced with a system that would be fair and equitable.
Abbott said schools would receive the same amount of funding as they would have under Labor - despite Pyne's warning that he could not guarantee individual schools would get the money they had been expecting from the Gonski reforms.
"We are going to keep the promise that we actually made, not the promise that some people thought that we made, or the promise that some people might have liked us to make," Abbott said.
Pyne also indicated that public schools could lose most if the Gonski reforms are dumped.
"That is of enormous concern to all jurisdictions." NSW Education Minister Adrian Piccoli said.
Private schools oppose the plan and say they do not want to benefit over the public system.
Meanwhile, the Government faces defeat in the Senate on its repeal of the carbon tax, with Labor and the Greens vowing to block the legislation. And it now plans to try to win the support of the Greens to lift the national debt level from A$300 billion ($335.2 billion) to A$500 billion, despite consistently attacking the Greens for their "fringe-dwelling"economics.
The Greens and Labor blocked the move in the Senate last month, supporting instead a A$400 billion limit. Treasurer Joe Hockey warned that if his plans were thwarted he would allow government services to grind to a halt and make "massive cuts" in spending.
