Emma McKeon has surpassed Ian Thorpe as Australia's greatest Olympic champion, winning her sixth gold medal.
On the first night in the pool, McKeon took out her sixth win and 12th medal overall as Australia won 4x100m freestyle relay gold.
What happened?
McKeon drew level with Ian Thorpe on five golds in Tokyo and had to wait three years to get another crack at the record.
Why it matters for Emma McKeon
The 30-year-old wasted no time taking out her sixth win, and 12th medal overall, as Australia won 4x100m freestyle relay gold on the first night in the pool.
McKeon was stunned to be reminded on the pool deck, saying "Wow. I don’t keep track of that kind of stuff. I hear it from you guys. It’s an honour really".
What comes next?
McKeon will now eye off more gold medals to extend her lead at the top, continuing her Paris campaign on Sunday in the 100m butterfly.
She is likely to also feature in the 4x100m medley relay and the 4x100 mixed medley relay, with Ian Thorpe celebrating her achievement, saying "It’s great. Couldn’t happen to a better person, really".
Thorpe thought McKeon had already surpassed him after Tokyo, but is pleased to see her taking it all in and "enjoying these moments".
McKeon's success is far removed from 12 years ago, when she narrowly missed selection for London 2012 and considered retiring from the sport, but she has persisted and is now the most successful swimmer, the most successful Olympian, in Australia.
McKeon's journey is a testament to her hard work, with the 30-year-old saying "If I look back at that young person — I think I was 17 when I missed London — you couldn’t have told her that I was going to go on to do this".
And she is not done yet, with McKeon looking to add to her medal tally in the coming days, and cement her place as Australia's greatest Olympic champion.
