   What I expect is a very hot week-end, and very interesting finals. I am happy to be back to Kazan as well. I hope to keep my lead. But I will mostly be focused on my own swimming, I will try to improve my time. First I visited the city in 2015, for the world championships, where I had my first individual races. Then we competed at the stadium, now – in the Aquatics Palace of Kazan. All in all, Russia is very different from Australia, but I like it. The competition will be held without spectators, like we did in Tokyo. That's our new reality. That does not help to swim, but there is no choice.

## Personal life

McKeon briefly dated fellow Australian swimmer Kyle Chalmers in 2021. In April 2022, McKeon began dating musician turned swimmer, Cody Simpson, although the couple did not confirm their relationship until July of the same year.
At the 2022 'Better Future for All' forum held at Griffith University, McKeon suggested that while "you do want to be inclusive" it is "not fair" to expect women to compete against transgender women.
