As Australia's athletes bid au revoir to Paris, the country's most decorated Olympian Emma McKeon leads a swag of retirements.
The 30-year-old will hang up her goggles having collected 14 medals across three Games, including six gold - an Australian record - three silvers and five bronze medals.
"I'm really happy that I was able to step up when it did come to the Olympics," McKeon said.
"I definitely will miss it. It has brought me a lot of great relationships and great experiences and shaped me into the person I am."
In Paris, McKeon won gold as part of Australia's triumphant women's 4x100m freestyle relay team, a silver in the 4x100m medley relay and bronze in the mixed 4x100m medley relay.
Lauren Jackson came out of retirement to steer the Opals on to the Paris podium and collect her fifth Olympic medal and while she didn't see much court time in her last Games, the 43-year-old won admiration from teammates and rival players.

"Just her being here, you can feel the difference. There's a reverence for her that lifts us and just motivates us to give everything we have."

Ageless diver Melissa Wu, competing at her fifth Games, appeared to pass the torch to teenage star Ellie Cole.
Overcoming a serious back injury to compete in Paris, the 32-year-old reflected on stellar career.

"I don't think I've actually missed any final at any major event in my whole career, so that's pretty insane."
