In May 2016 the Australian Medical Association and the Australian Institute of Sport released a statement recommending children aged under 18 who suffer concussion should not return to the sporting field until at least two weeks after their symptoms have cleared.The voluntary guidelines came out of a joint-project between the AMA and AIS, which saw the creation of a government-funded website, resources and warnings for parents, coaches and sports administrators to be more cautious when allowing children with head injuries back on the field.
