David Gonski has urged the Abbott government to reverse its decision to scrap the school funding reforms associated with his name, claiming "the concept of aspiration ends in 2017".

The Coalition's first budget put a bullet in the final two years of the so-called Gonski agreement, with a move to lower, inflation-based funding increases.

In his first public comments on education since the Coalition took government, Mr Gonski savaged the quality of advice offered by Prime Minister Tony Abbott's hand-picked Commission of Audit, which informed the education cuts in the budget.

"My biggest regret with the views of commission is their suggestion that the funding of 2018 should be based on 2017 funding indexed [to] changes in the CPI and the relevant wage price index," he told an audience at Melbourne University on Wednesday night.
