Some of Victoria's wealthiest private schools have reaped huge government funding increases, while disadvantaged public schools have been hit with cuts.

The average public funding of some of Victoria's most elite private schools increased at eight times the rate of the neediest public schools, a new analysis reveals.

Korowa Anglican Girls' Schools has emerged as one of the biggest winners of Australia's "incoherent and unfair" funding system, according to an analysis of the most recent My School data by Trevor Cobbold, a former Productivity Commission economist and convenor of public education lobby group Save Our Schools.

Mr Cobbold found that the average state and federal government funding increase per student for selected Victorian private schools was 25 per cent from 2009 to 2013, compared to 3 per cent for selected disadvantaged state schools.
