Emma McKeon has won her record-breaking 11th Commonwealth Games gold medal in the women's 50m freestyle.

She now has the most gold medals out of any Commonwealth Games athlete, overtaking long-time legends of the sport including Leisel Jones and Ian Thorpe.

It was a clean sweep for Australia in the event, with Meg Harris winning silver and Shayna Jack defying a serious hand injury she sustained at June's world championships to claim bronze.

It was one of many highlights from the pool on the third day of competition in Birmingham.

Madison Wilson, Kiah Melverton, Mollie O'Callaghan and Ariarne Titmus also won gold in the women's 4x200m freestyle final — demolishing the world record in the process and beating second-placed Canada by more than 12 seconds.

"The 4x2 means so much to us in Australia," Melverton told Channel Seven after the race.

"It's just nice to finally get that world record back in Australia's hands."

Australia also won the 4x100m freestyle relay a day earlier, courtesy of Wilson, O'Callaghan, Shayna Jack and — surprise surprise — Emma McKeon.

Kaylee McKeown also added to Australia's swimming goldrush with a win in the 100m backstroke final, narrowly defeating defending Canadian champion Kylie Masse in a highly-anticipated showdown.

Jenna Strauch earned silver in the 200m breaststroke final, Zac Stubblety-Cook nabbed silver and Sam Williamson got bronze in the 100m breaststroke, and Tim Hodge and Blake Cochrane won silver and bronze respectively in the men's S8 100m breaststroke.

Australia sits comfortably on top of the overall Birmingham 2022 medal tally at the end of day three with 52 in total — 22 gold, 13 silver and 17 bronze.

Gymnast Georgia Godwin, the women's rugby sevens team and cyclists Georgia Baker, Jess Gallagher and Matthew Richardson are also among the Aussies who scored gold on day three.
