Save Our Schools reported in May 2021 on the growing resource disadvantage of public schools, compared to private schools. According to the SOS report:
Figures recently published by the Australian Curriculum, Assessment and Reporting Authority (ACARA) on its National Report on Schooling data portal show that income per student of Catholic and Independent schools is much higher than for public schools and that their income has increased six to eight times that of public schools since 2009. The increasing resource advantage of private schools is mainly due to much larger government funding increases than for public schools.
