Yes, absolutely. We've just seen piloted last year an initiative to reduce the height at which contact can happen, and that's correlated across other sports. We have seen a reduction in concussion-related injuries since hockey made changes to their game, so we are going to be looking to implement a tackle height and reducing the tackle height. We have seen that being effective in other sports. Through global research, we have seen that concussion-related injuries increase when the height of the tackle is up at around the shoulder and head area.
Where we introduce tackling, which at our U11 level, that's going to be below the waist. How we coach that area and introduce tackling is to make sure that the body height comes down. We have seen that if you make changes to the laws or the rules of your game, that can reduce the likelihood of concussion-related injuries. The other one is zero tolerance for contact to the head, zero tolerance meaning zero tolerance, and the sanctions have seen a reduction in contact to the head.
