Full replay: Day 8 - Evening session - World Athletics Championships 2022
The 30-year-old is now the only woman to win back-to-back world titles in the javelin throw, and joins Cathy Freeman, Jana Pittman, and Sally Pearson on an illustrious list of Australians with multiple gold medals.
An Olympic bronze medallist, Barber was so nearly joined by compatriot Mackenzie Little on the podium, only for Winger and Kitaguchi to overtake the 25-year-old with their final attempts.
Team Australia now have two gold medals and a bronze medal at the Oregon-based competition, after Barber joined medallists Eleanor Patterson (gold, high jump) and Nina Kennedy (bronze, pole vault).
