Students at Kirwan State School will receive $500 to further enhance their efforts to protect the Great Barrier Reef through the Great Barrier Reef Marine Park Authority's (GBRMPA) Ripples of Change grants program.

GBRMPA Reef Guardian Director Karen Vohland said the grant would allow students to continue and expand on their environmental work.

"Kirwan State School has been actively involved in the Reef Guardian Schools program and have been recognised for their efforts to educate students about recycling, biodiversity and being self sufficient," she said.

"This funding will be used to extend their environmental activities by upgrading garden beds through the purchase of essential resources."

Twenty $500 grants are awarded by the GBRMPA each year to assist Reef Guardian Schools to undertake small environmental projects within their schools.

The schools nominate a project they would like to initiate and present a project plan to the GBRMPA.

The selected schools receive their grants early in the year to allow them time to implement their projects within the school year cycle.

Reef Guardian Schools is an environmental education program run by the GBRMPA.

The program aims to create awareness, understanding and appreciation of the Great Barrier Reef and its connected ecosystems.
