CHELSEA CASSIO
SCREENWRITER






After graduating from film school, I sold my first short film, Imaginary Friend, to ABC (Australia). Since then, I’ve written multiple episodes of series television, including The Doctor Blake Mysteries (BBC/ABC), Secret Bridesmaids’ Business (Channel 4/7 Network), Miss Fisher’s Modern Murder Mysteries (Acorn TV/7 Network), Troppo (Amazon Freevee), and Return to Paradise (BBC/ABC).
My original work sits in the darker genres, including grounded sci-fi, psychological horror, crime and mystery. I’m drawn to stories where perception can’t be trusted and characters realise they're living in a false or unstable reality. This is explored in my sci-fi series The Others, selected for the 2023 UGC Writers’ Lab at Series Mania in Lille, France.
In 2023, my crime series won Best TV Pilot Screenplay at the Prix Royal: Paris Screenplay Awards and was a finalist at the Swedish International Film Festival, New York International Screenplay Awards, and the Fabrique du Cinéma Awards in Rome. My TV series Cloak received development funding from VicScreen, where I collaborated with producer Simon Mirren (Versailles, Criminal Minds). My series concepts have been optioned by Mediawan (France), Federation Studios (France), Atlantic Nomad (UK), and in Australia: Easy Tiger, Hoodlum Entertainment, Princess Pictures, Curio Pictures and Seven Studios.

I'm a graduate of the Writers' Homicide School in Las Vegas, where I honed my skills as a crime writer, and I’m currently developing original television projects with European producers, focused on premium international genre storytelling. I enjoy collaborating with teams, building ambitious series for global audiences.
