Knockout Outdoor has officially announced the full lineup for its massive 2025 edition, Return of the Circuz, set to take place on Saturday, 4 October at ENGIE Stadium and surrounding grounds in Sydney. Delivered by HSU Events, this year’s edition promises to be Australia’s biggest hardstyle festival yet—and possibly the largest of its kind in the entire Southern Hemisphere.

With over 40 artists performing across three unique stages, Knockout Outdoor 2025 is bringing together some of the biggest names in the harder styles, including Brennan Heart, D-Block & S-te-Fan (Ghost Stories), Rebelion (Beyond The Horizon), and Adrenalize with a special Journey set. Fans can expect a high-energy mix of rawstyle, hardcore, euphoric, and uptempo sounds, with several live performances and exclusive themed sets throughout the day and night.

The festival will be split across The Stadium, The Mega Pit, and The Oasis—each offering its own atmosphere, sound, and experience. HSU is also promising the largest stage ever built in Australia, paired with world-class production and immersive visuals.

Presale tickets go on sale Thursday, 8th May, with pre-registration required for presale access. Known for consistently selling out, Knockout Outdoor 2025 is shaping up to be a truly unmissable event for hard dance fans.
