Grahamstown Public School received $15,000 and Raymond Terrace Public received $7050 as part of the NSW government's inaugural $2.5 million Sustainable Schools Grants.

The funding to Grahamstown Public will support a project involving the transformation of an area of the school grounds into a more structured and relevant space.

"The students currently use the natural environment for imaginative and creative play and the school is seeking to foster and enhance this process through the introduction of sensory equipment such as musical instruments, texture paths, and seating made of natural materials," said Parliamentary Secretary for the Hunter, Catherine Cusack.

"They also aim to build learning experiences for the students by installing a weather station, creating native animal habitats including possum and bird boxes, and a frog pond, and developing more native flora endemic to the area."

Raymond Terrace Public has two aquaponics systems within its school garden that requires additional funding to maintain its functionality.

"Students have shown great interest in this area, and it has allowed teachers to promote student leadership through a hands-on approach," Ms Cusack said.

"The grants scheme will empower students and school communities to implement projects that will benefit the environment by helping to save energy or water, reduce waste, or improve biodiversity."

"These schools and their students are showing all of us we can take personal responsibility for sustainability - there are things we each can do - and by playing their part with such thought and creativity they make me feel very optimistic for Australia's future".

Education Minister Sarah Mitchell said 194 NSW public schools received grants ranging from $1000 to $15,000 each.

"I encourage other schools to start thinking of applying for the next round of grants," she said.
