Australia's Bronte Campbell has expressed her disbelief after coming out of her sister Cate's shadow to win gold in the 100m freestyle final at the World Championships today.
The 21-year-old touched the wall in 52.52s, a personal best time for the swimmer, to beat Sweden's Sarah Sjostrom and Cate Campbell.
"I can't believe it," Bronte told Eurosport. "That was a stacked final. I can't believe I managed to get my hand on the wall first. I normally go out really hard so I'm just glad I got to hang on. It's my fastest time ever, I'm really happy to put a good race in the final."
Australia have won 10 medals so far in Russia.
