Teenage tyro Steve Solomon has become the first Australian in 24 years to qualify for an Olympic men's 400m final.
Solomon, 19, clocked his second big personal best in the space of two days in Sunday's semi, clocking 44.97 seconds to finish third in his heat.
It proved enough for him to advance to Monday's final in seventh place overall.
Lalonde Gordon of Trinidad and Tobago was the fastest qualifier in 44.58.
The last Australian to contest an Olympic men's 400m final was Darren Clark, who finished fourth at Los Angeles in 1984 and Seoul in 1988.
