Rohan Browning is on target for Tokyo after becoming just the second Australian in history to break the 10-second barrier in the 100-metre sprint.
The 23-year-old Sydneysider posted the wind-assisted time of 9.96 seconds at a track event in Wollongong, which was the fastest on Australian soil for 18 years.
His time is fourth on Australia's all-time list in all conditions, behind three times set by Indigenous athlete Patrick Johnson.
Johnson was the world's first person without African heritage to record a legal time under 10 seconds when he ran 9.93 in 2003.
Browning's tailwind of 3.3 metres per second falls outside the 2.0m/s recording required for the history books and Olympic qualification, however, puts him well in the frame for Tokyo selection.
Browning competed at the Commonwealth Games in 2018, finishing ninth in his 100 metre semi-final with a time of 10.26.
His personal best before Saturday was 10.08, which saw him break a decade-long drought without an Australian entry in the 100m at the 2019 world championships in Doha.
A week ago Tasmanian Jack Hale broke a 55-year-old record by clocking the fastest time ever by an Australian over 100 yards.
The 22-year-old clocked 9.43 seconds - eclipsing the mark of 9.52 set by Olympian Gary Eddy.
