Career
Chiarella attended the Australian Film, Television and Radio School (AFTRS), during which he completed an internship. He edited pre-visualization work for Baz Luhrmann's Australia. He also edited feature film Teenage Kicks by director Craig Boreham, and acclaimed short film The Love Song of Iskra Prufrock, for which he received an Australian Screen Editors Award for editing. He subsequently moved into directing, working on promotional campaigns for numerous Foxtel television series. He has also worked in development for showrunner Tony Ayres' production company, TAP.
His short films have screened at international film festivals to broad acclaim, earning him nominations and awards from the Australian Director's Guild, the Australian Academy of Cinema and Television (AACTA), and the Melbourne Queer Film Festival.
Chiarella wrote and directed the acclaimed short film Dwarf Planet, which screened at the 68th Sydney Film Festival and the Clermont-Ferrand International Short Film Festival in 2021.
In 2025, Chiarella won an AWGIE award for the episode of the SBS anthology series Erotic Stories he wrote, titled "Walking Gambit".
Chiarella has cited Hou Hsiao-Hsien, Wong Kar-wai, and Chen Kaige as film-making inspirations. Leviticus premiered at the 2026 Sundance Film Festival and was subsequently acquired for international distribution by Neon. He has been vocal about the importance of queer representation in cinema. Chiarella has also stated that casting for Leviticus drew on his admiration for the "bold, punk style" of 1993 crime comedy-drama Bad Boy Bubby; Nicholas Hope appears in Leviticus as the Deliverance Preacher. Other notable inspirations include cult classics A Tale of Two Sisters, It Follows, and Let The Right One In.
Chiarella is signed with Cameron's Management and WME.
