O'Neill is a Scottish-Australian flyweight who fights out of Fight Ready with an extremely high-output pressure style, landing nearly eight significant strikes a minute. Injuries and layoffs have slowed a once-fast rise, but she has won consecutive fights since her 2023 submission loss to Ariane Lipski. She returned in March 2026 and knocked out Gabriella Fernandes in the first round.
