Education Minister Simon Birmingham believes some private schools are over-funded, conceding they could be worse off if the government got its way.
Senator Birmingham refused to create a "hit list" of schools that could face funding cuts, but insists the way money is distributed is unfair.
"Some schools that are notionally over-funded take more than 100 years to come into alignment with the current funding model,' he told ABC's QandA program on Monday evening.
