Peta Sergeant is an Australian-Malaysian actress, born in 1981 in Malaysia and raised in Brisbane, Australia. While in high school, she had dreams of becoming a marine biologist, but a hobby for drama acting prompted her to audition and gain acceptance at the National Institute of Dramatic Art, from which she graduated in 2000 at the age of twenty. Despite landing television roles and even producing a play fresh out of drama school, Peta decided to step away from the industry and travel overseas for eighteen months, an experience that helped deepen her commitment to acting. Her notable television credits include the British science-fiction drama series Jeopardy and Headland, along with numerous Australian drama series such as Last Man Standing, All Saints, Canal Road, and Satisfaction. She has also starred in the films Iron Sky and Crawlspace. In 2020, Sergeant portrayed Terisa Kerrill in the Star Wars: Squadrons video game, and in 2021, she joined the cast of Supergirl, a role previously played by fellow Once Upon a Time actor Peter Gadiot before being taken over by The Odd Couple actor Thomas Lennon.
