Hunter Plantscapes designed the project, which included landscape design and the installation of seven garden beds, and students gained green thumbs planting fruit trees and vegetable seedlings.

School principal Benjamin Durie was thrilled with the enhancement to the garden, which can be used by students, families and local residents.

"We have seen great success with students immersing themselves in the community garden," he said.

"It offers our teachers some richer learning opportunities, promotes a healthy sustainable lifestyle and develops a sense of pride for students who have been involved in the planting program.

"It's also a quiet and peaceful space for students and the whole community to visit, providing a natural environment filled with strong sight, touch and smell impacts."

Mr Durie said the school plans to harvest the produce from the garden and use it as ingredients in the students' cooking classes.

The donation was part of the Yancoal Austar Community Support Program, which aims to make a positive difference in the local community and the lives of the people who work and live in the areas it operates.

"We are very pleased to be helping fund these wonderful improvements to the school community garden that will benefit Millfield Public School students and the wider community," Austar Coal Mine operations manager Brian Wesley said.

"Our Community Support Program is designed to help make a positive difference to the people that live in our local community and this is a sustainable project with the potential to be used by hundreds of students and residents in the years ahead."
