Marn Grook is a traditional Indigenous Australian game that combines elements of football and other ball games. It is played with a large ball, often made from animal skin, and involves players kicking the ball high into the air. The objective is to catch the ball and score points by kicking it between goalposts. The game has deep cultural significance for many Aboriginal communities and is often played during gatherings and celebrations. Marn Grook is believed to have influenced the development of modern Australian rules football, showcasing the rich sporting heritage of Indigenous Australians.
