Those of us in state schools know private schools are overfunded. Just look around!

NSW is over-funding private schools by $160 million, with some receiving almost $3 million more than they need from state coffers this year while public schools remain under-paid by almost half a billion dollars, a new report has found.

When state and federal money is combined, 30 of the state's high-end private schools are being over-funded by between $1 million and $7 million each in 2018. They include Oakhill College, Loreto Kirribilli and St Aloysius.

Meanwhile, the NSW public school system this year received $470 million less from the NSW government than was needed to meet the state's share of the Schooling Resource Standard, the benchmark for adequate funding.
