Heat policy
Below is a link to the AFL’s guidelines for prevention of heat injury. As a guide, we encourage every club to follow the guidelines to ensure that every player who plays the game is safe from heat stress and injury. Your State or league/association may already have a heat policy, we recommend that you liaise with them to ensure you are using the most appropriate policy/guidelines.
