From Sydney’s Suburbs to Westeros: Milly Alcock Age, Height, Figure, Net Worth, Bio, Boyfriend and Family

She worked part-time at a café in Sydney’s Marrickville before the whole world knew her name. That’s the Milly Alcock story — raw, real, and genuinely inspiring. Today, Amelia May “Milly” Alcock is the actress who breathed fire into young Rhaenyra Targaryen in HBO’s House of the Dragon, earned herself the role of Supergirl in the DC Universe, and did it all before turning 26. Here’s everything you need to know about her age, height, figure, net worth, bio, boyfriend, and family.

Milly Alcock — Complete Bio Table

Early Life & Family- A Sydney Girl Who Chose Acting Over School

Milly Alcock was born on April 11, 2000, and raised in the Sydney suburb of Petersham. Her parents — her father Mr. Alcock and her mother Emma Alcock — separated when Milly was young, and she grew up in a middle-class household with her two younger brothers, Bert and Eddy Alcock. Interestingly, while her family had a keen interest in Rugby Union, Milly’s heart was always set on something entirely different. She was introduced to acting upon playing Little Red Riding Hood in Taverners Hill Infants School’s version of Little Red Rocking Hood — and that one school play changed the course of her life.

Her mother Emma, who studied economics and finance at the University of Sydney and now works as a commercial director at PagerDuty, has always been a pillar of support. Milly has openly mentioned living in her mother’s attic before landing her career-defining role — a detail that makes her success all the more relatable.

Age & Education — 26 Years Old and Just Getting Started

At 26, Milly has already done more than most actors achieve in a full career. She attended the local Stanmore Public School and then Newtown High School of the Performing Arts, from where she dropped out in 2018 when she was cast in Upright. It was a bold gamble — choose education or choose the role of a lifetime. She chose acting, and it paid off spectacularly. She has also mentioned that she was just ten years old when Game of Thrones first premiered — and years later, she’d be starring in its prequel.

Height, Figure & Appearance — Effortlessly Captivating

Milly Alcock stands at 5 feet 5 inches (165 cm) and weighs approximately 50 kg (110 lbs). She has striking light brown hair and expressive brown eyes that translate beautifully on screen — whether she’s commanding a dragon or walking the West End stage. She maintains her physique through regular yoga, gym sessions, and an active lifestyle. There’s an unpretentious, natural quality to her appearance that has made her a favourite among casting directors and fashion photographers alike. She’s been dubbed a rising star by Vogue Australia, and it’s not hard to see why.

Career — From Café Worker to Supergirl

Milly’s path to stardom wasn’t a straight line — it was a long, winding road paved with Australian TV commercials, small roles, and sheer determination. She appeared in commercials for NBN, Cadbury, KFC, and Woolworths before making her television debut as a teenager in a 2014 episode of the Network Ten romantic comedy Wonderland. Small roles in High Life, Janet King, A Place to Call Home, Fighting Season, Pine Gap, and Les Norton followed — each one adding another layer to her craft.

The turning point came with the Foxtel comedy-drama Upright (2019–2022), in which she played Meg, a runaway teenager hitchhiking 2,000 miles across the Australian outback alongside Tim Minchin. For her performance, Alcock was nominated for Best Comedy Performer at the 10th AACTA Awards, making her one of the youngest nominees in the category. She also received the Casting Guild of Australia Rising Star Award — a sign of things to come.

Then came the role that made the world stop and pay attention. Cast as young Princess Rhaenyra Targaryen in HBO’s House of the Dragon (2022) — the massively anticipated Game of Thrones prequel — Alcock garnered critical acclaim and was considered a highlight of the series’ opening episodes. Her performance earned her a Critics’ Choice Television Award nomination for Best Supporting Actress in a Drama Series. You can explore the full series on the official HBO website.

And the career rocket didn’t stop there. In January 2024, it was announced that Alcock had been cast to play Kara Zor-El / Supergirl in the DC Universe film Supergirl (2026), first making a cameo appearance as the character in Superman (2025). She also starred alongside Julianne Moore and Meghann Fahy in the Netflix dark comedy series Sirens (2025).

Milly Alcock’s estimated net worth in 2026 sits between $2 million and $3 million USD, built through a combination of Australian TV series, major HBO productions, Netflix projects, commercial endorsements, and her upcoming DC Universe appearances. Given that her biggest paycheques — Supergirl (2026) and the continued House of the Dragon legacy — are still on the horizon, this figure is poised to grow significantly in the coming years.

Boyfriend & Personal Life — Private, Grounded, and Focused

When it comes to romance, Milly keeps things firmly off-camera. As of 2026, she has not publicly confirmed any relationship. There were brief rumours in 2019 about a connection with Ari Kwasner-Catsi, but nothing was ever confirmed. She is currently regarded as single and very much focused on her rapidly accelerating career. She has spoken openly about prioritising her craft over celebrity culture, and it shows in the quality and diversity of the roles she chooses.

Off-screen, Milly is a yoga enthusiast, a dedicated gym-goer, an avid reader, and someone who genuinely loves spending time with close friends. She’s active on Instagram with over 1.4 million followers, where she gives fans a genuine, unfiltered glimpse into her world. For similar profiles of bold young talents, visit TechnoSports.co.in.
