What started out as an opportunity to tap into some of the hidden artistic skills of students at Bexley Public School could end up with a national award.

Already named the NSW winner of the Paint Australia Beautiful Schools Mural Competition, Bexley Public’s painted panorama, 'Our Living Country', is now line to be recognised as the best in the land.

Honouring Aboriginal and Torres Strait Islander culture and surrounding biodiversity, the mural was very much a whole-school project taking around four months to complete.

“There’s a part from every individual child in it,” Bexley principal Scott McCardell said.

“We’ll find out if we’re successful at the end of December, but I think we are already pretty successful in terms of selection from the state.”

The school started on the project by creating a High Performance and Gifted Education (HPGE) group from across Kindergarten to Year 6, opening it up to students who showed an interest in art.

Every week, they met for additional lessons with local artist Terry Evans and came up with a design blueprint that was adjudged best in state.

Brought to life with donations supplied by Haymes Paint, the design celebrates the connection between people, nature, and country through three panels representing the past, present, and future.

"They've come up with something substantial for the school, not only for now, but for the long term. It has been a real labour of love for them and something we should be very proud of," Mr Evans said.

Assistant principal Kathie Cvijetic, who drove much of the project, hopes to inspire students and the community to appreciate and protect the environment.

"The students are so proud and love that this mural will be part of the school long after they've gone. As a teacher here for over 20 years, that legacy means a lot to me, too," she said.

Voting for the competition, which is run through Keep Australia Beautiful and on its Facebook page, closes at 12pm on October 31 with the national winner to be announced on November 5.

The mural is only a part of the recent transformation at Bexley Public School.

Alongside the artwork unveiling the school got a chance to show off its impressive new playground and interactive native garden.
