Infinity (est. 2020) is a theatre and experience oriented company whose work is centred on youth culture, driven by the perspectives and interests of its young members aged 15 to 23. Based in Naarm/Melbourne and Djilang/Geelong, Australia, Infinity is led by director and artist Jackson Castiglione, working alongside five young leaders who co-devise, perform and mentor other young artists across the company's projects and activities.

Infinity makes performances in response to emerging cultural trends and the changing ways young people choose to entertain themselves, exploring how they engage in art-making and participation through cosplay, fandom and niche subcultural trends. Infinity's work challenges artistic forms to engage different audiences and to best serve its ideas and process.

Infinity has had work commissioned by; The Substation (Newport) and RISING Festival - ‘Anything & Everything’ (2021 & 2022, Naarm/Melbourne), Hong Kong Arts Festival - ‘All Things at Once’, a transmedia performance made in collaboration with six young Hong Kong artists (2024 Hong Kong), and most recently, ‘Monsteen’, a psychologically immersive horror experience, premiered at the 2026 RISING Festival, supported by Creative Australia, Arts Centre Melbourne and SIGNAL Youth Arts. Infinity has also had work presented at IOTF, Boston, USA.

Infinity is currently developing a new transmedia theatre work in collaboration with young artists from Hong Kong and Australia for OzAsia Festival and Resplendence a reimagining of Swan Lake by untrained children.
