HSU’s Knockout Outdoor 2025 – Return Of The Circuz lit up the Sydney Showground yesterday, 4th October, delivering a full-scale hard dance spectacle for the ages. With over 60,000 fans in attendance, this year’s edition not only marked one of the biggest festivals in Australia, but also unveiled its much-hyped 40th surprise act—D-Sturb.

Taking to The Megapit stage from 7pm to 7.45pm, D-Sturb stunned the crowd with a high-powered unannounced set. One of the biggest surprises came when he dropped his own euphoric remix of "What’s A Girl To Do" by Fatima Yamaha, a melodic twist that sent shockwaves through the arena. Fans erupted as the Dutch powerhouse delivered a performance that balanced emotional highs with punishing raw energy.

The secret set was one of many highlights across a stacked lineup featuring Angerfist, Rebelion, D-Block & S-Te-Fan, Brennan Heart, Lil Texas, and more. Special showcases like Best of 170, The Journey, and multiple live acts—including Imperatorz, Unresolved, and Regain—kept every stage firing across the day and night.

The festival closed with a jaw-dropping end show that featured one of the biggest stage productions ever seen at Knockout Outdoor. Towering structures, full-scale pyrotechnics, and an incredible fireworks finale sealed the deal on what will go down as one of HSU’s most ambitious and unforgettable productions to date.
