Sprinter Evan O'Hanlon has again stamped his authority over the 100m distance with a world record Paralympic gold medal performance in London.
The Melbourne 24-year-old was never threatened during Saturday night's T38 class event, in which he recorded a run of 10.79 seconds.
"For me it wouldn't have been a win if I didn't run a new world record in the process," he said.
A gold medallist in the same event at the 2008 Beijing Games, O'Hanlon was racing against records rather than opponents.
"I wasn't really trying to race the other guys, I was racing myself," said the incumbent Paralympic and world record holder.
And despite his winning margin of 0.32 seconds, O'Hanlon thinks he can find more speed.
"To be honest I thought I could go faster than that. Maybe just tonight wasn't my night ... I think I can get down below 10.6."
O'Hanlon's gold was one of three track and field medals for Australia on Saturday.
Brad Scott won bronze in the T37 800m with a time of 1 minute, 57.22 seconds.
The 24-year-old Canberran slipped from his silver medal finish at Beijing.
In the women's F46 javelin Victorian Madeleine Hogan snatched a bronze medal with her final throw.
Positioned fourth after five rounds, the 23-year old's final attempt was a personal best of 38.85m.
Asked of her thoughts leading into the final throw, Hogan said her mind turned to coach John Eden's reaction if she had missed a medal.
"I just thought: Oh my God, John's going to be so angry".
At the close of day two of athletics competition, Australia has one gold and four bronze medals from the stadium.
