The Koori Knockout is an annual Aboriginal Rugby League carnival that has been held since 1971. It is one of the largest gatherings of First Nations people in Australia, with approximately 25,000 community members attending over four days. The event is hosted by different teams each year, and it features competitions across mens, womens, and junior tournaments. The Koori Knockout is a celebration of community, family, and Indigenous rugby talent.

The first knockout was held in 1971 at Camdenville Park, St Peters, with seven participating teams. The event was initiated by six men and one woman affiliated with Koorie United, who proposed holding a statewide Knockout competition. The establishment of the Knockout set out with different objectives than previous town-based knockout football and basketball competitions.

The Koori Knockout is an opportunity for Indigenous families to connect and showcase their rugby league talent. It is also a chance for people to represent their family and bond with relatives. The tournament has attracted big names, such as NRL players Latrell Mitchell, Josh Addo Carr, and Nicho Hynes.
