Rohan Browning reckons it's only a matter of time before he joins countryman Patrick Johnson in the exclusive sub-10 second club after clocking the fastest 100m time by an Australian on home soil.

Browning's flying effort of 10.02 seconds at the national championships on Saturday was also the third quickest ever by an Australian - behind only Johnson's national record of 9.93 set back in 2003 in Japan and his own personal best of 10.01 at the Tokyo Olympics.
