Mollie O'Callaghan has pipped Ariarne Titmus to the 200m freestyle gold medal in Australia's first one-two at the Olympics in 20 years.
The medals were Australia's first in the pool since opening night with O'Callaghan picking up her second triumph alongside a 4x100m freestyle relay gold, while Titmus added a silver to her 400m freestyle victory.

Who won the women's 200m freestyle final?
O'Callaghan touched the wall in an Olympic record 1:53.27, slightly ahead of Titmus at 1:53.81, with Hong Kong's Siobhan Haughey in third with a time of 1:54.55.
Titmus was well short of the 200m freestyle world record (1:52.23) she set at the Australia Swimming Trials in June.
O'Callaghan, 20, powered ahead of Titmus in the final lap after being fractionally behind when they turned for the final 50m.
The gold and silver medal double was Australia's first at an Olympics since Ian Thorpe and Grant Hackett in the 400m freestyle at Athens 2004.
With Titmus going into the race as favourite and world record holder, O'Callaghan revealed her mentality to help win the gold.
"You’ve got to accept the challenge at the end of the day. You can either run or either fight. I chose to fight," O'Callaghan said post-race.
"I’m always striving for more and I always put a lot of pressure on myself. My expectations are very high. That was an amazing race. I’m always wanting that little bit more.
"I just had to go with Dean and trust him knowing what to do and what’s best. To be honest, I did it for the country, I didn’t do it for myself. I’m racing for all these people. I just had to put it behind me. Less pressure now, I get to swim freely.
"It’s such an honour to be with everyone, and compete against Arnie. She is an absolute gun. She races like an absolute beast. And it’s an honour to train alongside her and have such a great team around us."
Ariarne Titmus vs. Mollie O'Callaghan previous history
At the Australian championships earlier this year, O'Callaghan took home the honours before Titmus reversed the result at the Olympic trials a few months later in a race which saw them both finish under the previous world record time.
On that occasion, Titmus, 23, touched in a time 1:52.23, just ahead of her 20-year-old teammate, who clocked 1:52.48.
In Monday morning's semi final, Titmus recorded a 1:54.54, while O'Callaghan was just .06 behind, laying the platform for what was an epic shootout in the final.
