TOORMINA High School and Coffs Harbour Senior College have two of the biggest maintenance backlogs in NSW with more than $1.7 million of repairs at each school lacking funds.
A freedom of information request by NSW Labor has revealed 34 Coffs Coast schools are sharing in a $10.1 million repairs funding shortfall - part of a $732 million statewide backlog.
Toormina High School needs $1,732,943 and Coffs Harbour Senior College has a $1,714,021 build-up of unfunded works.
Coffs Harbour Senior College has 480 enrolments, making the funding log-jam average out to almost $3571 per student.
Across the state, 120 schools have individual upkeep backlogs of more than $1 million each.
Labor leader Luke Foley said the State Government spent only $158 million on the backlog in 2014-15, even though it had grown by $195 million the previous year.
"The maintenance backlog is spiralling out control," he said.
"North Coast schools are being neglected while the government brawls with itself over how to spend billions on sporting stadiums in Sydney.
"Local schools need to be properly maintained to ensure the best environment for learning."
The Department of Education said it had greatly increased its school maintenance spend this financial year.
"Since 2011, the NSW Government has committed almost $4 billion to school infrastructure," a spokesman said.
"On an asset portfolio of this size, worth more than $25 billion, it is not feasible to have no backlog maintenance."
