Emma McKeon is officially Australia's greatest Olympian after she claimed a double dose of history on Sunday.
The Wollongong star closed out a near flawless campaign in Tokyo with a pair of gold medals on the final day of the meet.
McKeon started the session by taking out the 50 metres freestyle final in Olympic record time to become the first woman to achieve the 50m-100m double since Jodie Henry in Athens.
Cate Campbell then ensured the queen of the pool would finish the Games as the only Australian in history to win four gold medals at a single Olympics and seven of any colour by out-touching America's Abbey Weitzeil in the 4x100m medley relay.
It also makes McKeon the second person of any nationality to win seven medals at a Games, after Soviet gymnast Maria Gorokhovskaya achieved the feat in 1952.
The 50m freestyle gold took the 27-year-old past Ian Thorpe, Shane Gould and Alicia Coutts for most medals by an Australian at a single Olympics.
With four from Rio, McKeon now has 11 in her career, the largest total by an Australian, ahead of Thorpe and Leisel Jones on nine.
McKeon's five gold medals also have her level with Thorpe for most gold medals by an Australian.
Speaking in commentary, Thorpe was in awe of the swimmer's achievements this week.
"This has been Emma McKeon's meet," Thorpe said on Channel 7. "She's been dominant, she's been brilliant, she's been fantastic. It has been a pleasure to watch.
"She skips across the water in a way that we don't often see, she's quite slight in her physicality, but the way she's able to move through the water is impressive."
It's a remarkable achievement for a swimmer who has largely flown under the radar throughout her career, many perceiving her as a relay specialist.
McKeon has shone in the team events in Tokyo, winning gold in the 4x100m freestyle and women's 4x100m medley realys, and bronze in the 4x200m freestyle and mixed 4x100m medley relays.
The biggest change for the 27-year-old, however, has been her performances in the individual events at these Games.
McKeon secured bronze in the women's 100m butterfly before producing a stunning swim to take out the 100m freestyle final in Olympic record time.
Another pair of golds in the 50m freestyle and 4x100m medley relay on the final day of the competition is the perfect way to cap a near flawless campaign.
