Millaroo State School may be a small school of 27 students but they have big plans when it comes to protecting the Great Barrier Reef.

The Burdekin school is the latest school to pledge their support for the Reef by joining the Great Barrier Reef Marine Park Authority's (GBRMPA) Reef Guardian Schools Program.

GBRMPA Education Officer Carolyn Luder said the Reef Guardian students would get involved in more environmental projects that improve their local environment and the outlook for the Great Barrier Reef.

"The Reef Guardian Schools Program allows students to explore their catchment and work with the broader community to keep their region and the Reef clean," she said.

"They may be a small school but they have already assisted to implement recycling in their region in partnership with the Burdekin Shire Council.

"The school is also currently working on installing an aquaponics system to grow fruits and vegetables to use in their tuckshop and sell to the local community.

"As the future custodians of the Great Barrier Reef, these students have an important role to play in the future of the Reef."

Millaroo State School joins 10 other Reef Guardian Schools in the Burdekin region that are working together today for a healthier Reef tomorrow.

The Reef Guardian Schools Program is a voluntary stewardship program that develops partnerships between schools and their communities to work towards a sustainable future for the Great Barrier Reef.

In its ninth year, this education program currently sees more than 60 000 students committed to the protection and conservation of the World Heritage listed Great Barrier Reef.
