VANDALS smashed 18 windows at the Northern Rivers Conservatorium in Lismore on Saturday night, causing around $3000 in damage.
Executive director Anita Bellman said there was glass all over her desk and floor, as well as in the kitchen, concert room, another office and in the passage near the backdoor.
It is the second attack on the conservatorium in the past two months, with two windows smashed several weeks ago.
"We haven't got the money or the man hours to repair this," Ms Bellman said.
In fact the second and third floor windows will remain covered with black plastic until some other capital works are being undertaken early next year.
At that time they will replace the broken panes, all the window putty and Ms Bellman is hoping they will be able to put metal grills on the windows to stop any future attacks.
She said the cost of the repairs is equivalent to about 10 bursaries that are offered to people on low incomes who would not otherwise be able to afford their music tuition.
She said two thirds of The Con's clients are children and the attack on the building was an attack on an organisation that is deeply connected with the community of Lismore.
"There's the cost and the hassle, but it also shows a complete disregard," she said.
Police were called to the scene on Sunday morning after a maintenance worker first noticed the damage.
Police removed about six bags of forensic evidence including the rocks and paving stones that were used as projectiles and are hoping to obtain fingerprints from them.
There is no CCTV footage available and no further information from surrounding businesses.
