The rural school has been the only school from Ballarat to the South Australian border to maintain its five-star rating. 

St Mary's Catholic Primary School teacher Victoria Wilken said the school and students were leading the way for future generations. 

The school has built a veggie garden, planted fruit trees, encourage nude food and has worked towards being paperless over the past five years. 

Ms Wilken said the school has also changed the student's habits, which included turning off lights and closing doors when air-conditioners or heaters were on. 

"It is so important to be sustainable because if we do not look after what we have now then it's not going to be here," she said.

"Our school and students need to set an example for this town and our future generation - it is their world they have to grow up in and they have to look after what they've got." 

Student Evelyn said the school's leadership status in sustainability was "a big deal."

She said every person in the community has a responsibility to look after the environment.

Student Cody said he has learnt many ways to be a more sustainable person.  

"There are all types of things we can grow and reuse. We are making worm farms and using that to help grow our plants.

"I've enjoyed growing the produce and making sustainability bracelets to wear."
