Ella Nelson has become Australia's fastest woman over 200m since 2000 thanks to a stellar run in Canberra.
Nelson set a new personal best just a fortnight ago in the nation's capital, qualifying her for the Rio Olympics, but smashed it by 0.31 on Saturday with a 22.53.
Only six other women have sprinted faster over the 200m, but none since Melinda Gainsford-Taylor at the Sydney Games.
"I always felt like I could really drop something severe in the 200m, it was just a matter of when," she said.
"I felt like once I'd done the time two weeks ago, I just got so much more excited and really thought, 'What can I do?'"
Nelson admitted she felt ill before the race after shocking herself with a new PB in the 100m.
The 21-year-old, who was run out in the 200m heats at the 2015 world titles in Beijing, has had her eye on running a 22.50 for the past year - so much so she's had the number as her phone password.
"It was always in my sights," she said.
"But now I'm going to have to change it."
She capped an impressive evening for female athletes after two standout performances in the women's long jump.
Chelsea Jaensch met the qualifying mark of 6.70m at the Canberra Track Classic on Saturday, following Brooke Stratton, who smashed her personal best with a 6.94m.
Stratton had already qualified a fortnight ago in the nation's capital, but her new PB - achieved with no tailwind - pushes her to second on the Australian all-time list.
Only Bronwyn Thompson has jumped further (7.00m in 2002).
It puts Australia on track to have more than one contender in the event at an Olympics since the Los Angeles Games in 1984, which had three women.
"It was good jump quite far two weeks ago and to be able build on that this week, I'm absolutely ecstatic about it," she said after having a photo with two of the women she passed on the list, Nicole Boegman and Robyn Strong-Lorraway.
"It gives me a lot of confidence that I can jump seven metres one day.
"I'm only 22 years old, so I'm hoping I can get there in future."
Jaensch, 31, was the only new qualifier at the Canberra Track Classic.
Australian 100m record holder Melissa Breen fell 0.11 short of the Rio Olympic standard with a 11.43 run.
