There was more success for Australia in the pool as the women's 4x100 metre freestyle relay team clinched a record-breaking gold.
Australia broke their own world record on the way to claiming gold in the women's 4x100 metre freestyle relay final.
The quartet - consisting of Emma McKeon, Brittany Elmslie, Bronte Campbell and Cate Campbell - touched the wall in three minutes and 30.65 seconds, three tenths quicker than their previous marker set in 2014.
Australia trailed the United States in the early stages but had moved into the lead by the 300m mark and held on for the country's second gold in the pool, with Mack Horton having triumphed in the men's 400m freestyle earlier on.
The American team came home in second, finishing a second clear of Canada, who took the bronze medal.
