At just 18, Gout Goutt storms to a 19.67* world U20 record in the 200m, becoming the first Australian man in history to break the sub-20 barrier in wind-legal conditions and shattering the under-20 record previously held by Usain Bolt (19.93 seconds in 2004).

He caps it off by successfully defending his 200m national title at the Australian Athletics Championships
