Quirindi High School's Student Representative Council (SRC) coordinated a Jersey Day on Thursday, to raise awareness of organ donation.
Students and staff were encouraged to wear their favourite jersey to support the cause.
One organ and tissue donor can transform the lives of many people.
Australia is a world leader for successful transplants, and there are some 1,700 Australians currently wait-listed for a transplant.
The campaign is about raising awareness for a very important cause, encouraging others to think of the importance of organ donation and the gift of life it provides to those with serious medical conditions.
Thursday was not a fundraiser, but a sharing of knowledge to highlight a lifesaving cause.
