What Is Milly Alcock's Net Worth?

Milly Alcock is an Australian actress who has a net worth of $2 million. Milly Alcock first built her career in Australian television, appearing in series such as "Janet King," "A Place to Call Home," "Fighting Season," "Pine Gap," "Reckoning," and "Upright." Her breakout Australian role came on "Upright," in which she starred opposite Tim Minchin as Meg, a teenage runaway who forms an unlikely bond with a troubled musician while traveling across the Australian outback.

Alcock became internationally recognized in 2022 when she played the young Princess Rhaenyra Targaryen on the HBO fantasy series "House of the Dragon," a prequel to "Game of Thrones." Her performance helped establish the emotional foundation for one of the show's central characters before the role shifted to Emma D'Arcy. Alcock later made another major franchise leap when she was cast as Kara Zor-El / Supergirl in DC Studios' "Supergirl," giving her one of her first major Hollywood starring roles.

Australian Television Career

Alcock began her screen career in Australia as a teenager. Her first television appearance came in 2014 on the romantic dramedy series "Wonderland." She followed that with presenting work on "B.F. Chefs" and the Disney Channel Australia program "Hanging With."

She continued building her résumé with roles on "Janet King" and the miniseries "High Life." In 2018, she played Emma Carvolth on "A Place to Call Home" and appeared in the main casts of "Fighting Season" and "Pine Gap."

Alcock's biggest Australian breakthrough came in 2019, when she began playing Meg on "Upright." The series starred Tim Minchin as Lucky Flynn, a musician transporting a piano across Australia, with Alcock as the sharp, chaotic teenager who joins him on the journey. Her performance earned strong reviews and an AACTA Award nomination for Best Comedy Performer. She returned for the show's second season in 2022.

During the same period, Alcock also appeared on "Les Norton" and "Reckoning," further establishing herself as one of Australia's most promising young television actors.

House of the Dragon

In 2022, Alcock reached a global audience when she appeared in HBO's "House of the Dragon." The series is a prequel to "Game of Thrones" and is based on George R. R. Martin's book "Fire & Blood."

Alcock played the young version of Princess Rhaenyra Targaryen, the daughter of King Viserys I Targaryen and one of the central figures in the Targaryen succession conflict known as the Dance of the Dragons. Her performance opposite Paddy Considine, Matt Smith, Emily Carey, and other cast members helped anchor the early episodes of the series.

The role was later taken over by Emma D'Arcy after the show's time jump, but Alcock's version of Rhaenyra made a major impression. She brought the character a combination of intelligence, defiance, restlessness, and vulnerability, helping viewers understand why Rhaenyra became such an important and contested figure in Westeros.

"House of the Dragon" turned Alcock from a rising Australian actress into an international name. It also opened the door to major Hollywood roles and franchise casting.

Supergirl

In 2024, Alcock was cast as Kara Zor-El / Supergirl in DC Studios' new cinematic universe. The role positioned her as one of the key young faces of the rebuilt DC franchise under James Gunn and Peter Safran.

Alcock starred in the 2026 film "Supergirl," directed by Craig Gillespie. The movie was based in part on the comic book miniseries "Supergirl: Woman of Tomorrow" by Tom King and Bilquis Evely, and presented Kara as a harder-edged, more damaged figure than the more traditional hopeful Superman archetype. The cast included Matthias Schoenaerts, Eve Ridley, David Krumholtz, Emily Beecham, David Corenswet, and Jason Momoa.

"Supergirl" gave Alcock her first major lead role in a Hollywood superhero film, but the movie's theatrical performance was underwhelming. It opened below expectations and was widely described as a disappointing commercial start for the new DC Universe, especially given the momentum DC hoped to build after "Superman." While Alcock's casting and performance kept her profile high, the film's box office results were lackluster for a big-budget superhero release.

Other Work

Outside of television and superhero films, Alcock has continued to expand her résumé across film and stage. She made her feature film debut in the 2024 drama "The School Duel" and has also worked in theater. In 2024, she made her West End debut in "The Crucible," playing Abigail Williams in the Arthur Miller play.

Her career has moved quickly from Australian television to prestige HBO drama, London theater, and major Hollywood franchise work. That range has helped establish her as an actress capable of moving between intimate character roles and large-scale genre projects.

Personal Life

Milly Alcock has generally kept her personal life private. Before "House of the Dragon," she was still primarily known in Australia and was reportedly living a relatively ordinary life while working in local television. Her sudden international fame after the HBO series changed the scale of her career almost overnight.

Alcock has spoken about wanting to avoid being boxed into one kind of role. Her early career supports that goal: she has played comic, dramatic, fantasy, stage, and superhero characters while still in her 20s. Her trajectory from "Upright" to "House of the Dragon" to "Supergirl" made her one of the most prominent young Australian actresses of her generation.
