## Early Life 
Sebastian Sero was born on July 13, 2012, in Wagga Wagga, Australia. He is the eldest son of writer and screen actress Anezka Sero and brother to Luka Sero, born on March 3, 2014, who is also an actor and performer. 

Sero was homeschooled from a young age and trained as a figure skater, competing for Victoria and Australia at Ice Skating Australia sanctioned competitions. As a part of his figure skating training, he began dance lessons at the Australian Ballet School and a Brunswick based performing arts school where his talent in singing and dancing was spotted. He was signed to the attached theatrical agency and began acting in television commercials and was cast in his first professional musical, Fun Home in 2022 as John Bechdel, a role he shared with his younger brother Luka Sero. 

Given the demanding nature of the role and the late nights required by his theatre performance schedule, Sero ceased competing in figure skating, continuing with his dance and singing training as he was soon cast in further professional theatre roles. 

## Career 
Following his performance in Fun Home, Sebastian Sero performed in the Victorian Opera's production of The Who's Tommy as Young Tommy and was cast in the Australian professional touring production of Mary Poppins which he shared with his brother Luka Sero and several other boys. After the completion of the tour, Sero was cast in the touring production of Elvis: A Musical Revolution as Young Elvis, another role he shared with his brother Luka Sero and other local boys, performing in the Australian cities the Gold Coast, Perth and Melbourne. This performance garnered him critical acclaim, with Australian theatre critics in citing Sero as 'surely a star in the making'. 

Sero continued building his resume in 2023, appearing in the Australian Ballet's Anna Karerina, where he appeared as young Serghei Karerin (*Serozha*). During this time, he began writing music for his pop-rock band the Sero Brothers and started auditioning for screen roles. 

## Billy Elliot the Musical (2024-2025) 
Sebastian Sero debuted in the title role of Billy Elliot in a local production that opened at the National Theatre in Melbourne on May 10, 2024.  Sero's performance garnered critical acclaim, and he was invited to reprise the role in the Footlight Production's production of the show in 2025, amidst rehearsals for Round the Twist, an Australian musical adaptation of the critically claimed television series and a Queensland Theatre Company and QPAC co-production, helmed by Australian theatre director  (Love Never Dies). 

Sero performed as Bronson Twist in Round the Twist alongside his brother Luka Sero while rehearsing Billy Elliot, returning to Melbourne to perform the role with Luka, who took over the role while Sero began filming Anaconda on the Gold Coast early 2025.

## Flare 
Following the success of their pop releases, the Sero Brothers began exploring further musical influences, moving away from their musical theatre and pop roots into the alt-rock genres. 

In the Sero Brothers release *Walk On, Bye!* the brothers played electric guitar and drums in their music video and began writing the single *Better Than This*, inspired by their love of the Japanese alt-rock band One Ok Rock which draws influences from American supergroup Link Park and the emo-rock American rock band Fall Out Boy. 

In 2026, Sebastian Sero formed the alt-rock group *Flare* where he continued writing alt-rock inspired original songs with Luka Sero. The band will release their debut EP *Rise* in the year.
