Gout ran 19.67 (+1.7m/s) to set an Australian national record and Erriyon Knighton's 19.69 world U20 record. He had a surprise challenge from Aidan Murphy who set a huge 19.88 PB (previous best was just 20.41) to also break the previous national record. The showdown with Lachlan Kennedy never materialized as Kennedy was a last minute scratch after winning the 100m in 9.96 on Saturday. In distance action, Jess Hull returned from her 1500m fall to win the 5000m in 15:13, Abbey Caldwell beat Claudia Hollingsworth in the 800m (1:58.57 to 1:58.91) and Peter Bol took the 800m in 1:45.60.
