HSU Events has officially dropped the full lineup for Knockout Outdoor 2026: Level Up, confirming 39 artists across three distinct arenas at ENGIE Stadium and Sydney Showground on Saturday, 3rd October, 2026. The announcement delivers on the enormous anticipation that followed last week's ticket pricing reveal, with a roster spanning hardstyle, hardcore, uptempo and raw styles that firmly cements Knockout's reputation as the Southern Hemisphere's largest harder styles festival.

Headlining the bill are globally recognised acts including D-Block & S-Te-Fan, Da Tweekaz, Headhunterz, Sickmode, Warface, Wildstylez and Radical Redemption, joined by a wave of exciting stage concepts from artists such as Lekkerfaces presents Hyper Live, The Dope Doctor presents Ghost Mode Live, Ran-D presents Resonate, and Satirized presents Neon Funfair Live. Together these acts represent the very best of hardstyle and hardcore music performing at an Australian festival in 2026. Hardstyle veterans Tha Playah, Frontliner and Gammer appear in Journey Sets, while the Get Wrecked crew bring Aversion, Dual Damage and Kruelty to the lineup alongside Rebelion, Slaughterhouse and many more.

The three-arena experience spans The Stadium, featuring the highest festival main stage ever constructed in Australia, The Mega Pit offering a raw and core environment loaded with 72 lasers, pyrotechnics and maximised bass pressure, and The Oasis, reimagined as a fully immersive Boiler Room-style arena closing with a BKJN Uptempo Takeover. Presale tickets priced at $229.00 plus booking fee open at 12:00PM on Thursday, 7th May, 2026, with general public sales following at 12:00PM on Friday, 8th May, 2026.

Now in its seventh year, Knockout Outdoor has sold out at every edition to date, and with a lineup of this scale backed by the most ambitious production the event has ever seen, 2026 appears no different. Festival-goers are urged to secure tickets early, as every release tier has historically moved fast. Full details including stage breakdowns and set times are expected to follow in the weeks ahead.
