Australia's distance running stocks for the world athletics championships in Doha have received a significant boost on day one of the London Diamond League meet.
The national squad in Doha could now include a full complement of three runners in the men's 5000m after Stewart McSweyn, Patrick Tiernan and US collegiate star Morgan McDonald all dipped under the automatic qualifying mark of 13:22.50 at London Stadium.
The versatile McSweyn was the standout, finishing fourth in 13:05.63 in a quick race won in 13:01.86 by Ethiopian Hagos Gebrhiwet.
The rangy Tasmanian can keep his options for Doha open as he has also previously bettered the qualifying standard in the 1500m.
Rio Olympian Tiernan clocked a personal best of 13:12.60 to finish eighth in London and McDonald was ninth in 13:18.91.
National record holder Linden Hall took advantage of a red-hot pace in the women's 1500m to clock 4:04.29, also dipping under the world championships qualifying mark in the process.
Scottish star Laura Muir won in 3:58.25.
Red-hot javelin Kelsey-Lee Barber continued her breakout season by finishing second in the javelin behind Tatsiana Khaladovich from Belarus.
Barber's best of 65.85m was her second biggest throw in competition, further cementing her status as a genuine medal contender at the September 27-October 6 world titles.
The two-day meet concludes on Sunday (early Monday AEST) at the London Olympic Stadium.
