She was named 2020 Female Swimmer of the Year and Oceanian Female Swimmer of the Year at the Swammy Awards. Her four medals at the 2018 Youth Olympic Games in Buenos Aires were the most won by an Australian athlete in any sport at that edition of the Games.
Her older sister Taylor McKeown has also represented Australia in swimming, winning a silver medal in the women's 4x100m medley relay at the 2016 Rio Olympics. The athlete draws inspiration from Taylor's hard work and dedication.
Her father Sholto passed away from brain cancer in 2020. She has a tattoo on her foot that reads "I'll always be with you" in his honour. His passing has made her realise the importance of seizing life's opportunities.
Looking ahead, she aims to continue training under Mick Palfrey at USC Spartans. Her focus remains on overcoming her shoulder injury and preparing for upcoming competitions.
The athlete's journey is marked by resilience and dedication, inspired by family influences and personal challenges. Her achievements reflect her commitment to excellence in swimming.
