CANNONVALE State School's young authors, released their very first book yesterday.

'Buster the Bunyip Saves the World!' was created last year by students from Prep to Year Six who collaborated to produce pages of text and illustration for the story.

The book, supported by The Great Barrier Reef Marine Park Authority's Reef Guardian Schools program, was finally launched at the school's assembly yesterday.

Teacher and coordinator of the school's Reef Guardian program, Kerri Head said they presented special guests from Reef Catchments and Whitsunday Regional Council with copies of the book.

"We had our eco ambassador, Rachel Hutchinson present the book to the reef catchments and local library," she said.

The story follows Buster, a Bunyip with a heart "as big as Uluru" fixing environmental problems across the globe using his super strength, his ability to transport and ability to change colours depending on the level of danger in the area.

The book will be on display at the Cannonvale Library so local community members can have access to the story. 

Ms Head said the representatives took multiple books back to their respective organisations.

"Reef Catchments have taken it back to their organisation and they'll share it internally with other regions so they can share what ideas schools have (for the reef)," she said.

"The Great Barrier Reef Marine Park authority has also taken it back and are taking it outside our region and to other schools." 

Ms Head said the students found the experience to be invaluable and loved being involved in its creation. 

"It was almost as though they saw Buster the Bunyip as a super hero," she said. 

"When they put on (Buster's) mask, they felt invincible and they all got really into it," she said adding "even the preps (got involved) even though they weren't involved in writing it."
