South Australia’s forward-thinking electronic music festival Sidebyside is set to return in 2026 with its most ambitious edition yet. Taking place on Saturday, 31st January, at Tulya Wardli/Helen Mayo Park in the heart of Adelaide, the one-day celebration will feature a diverse lineup of local and international artists across two immersive stages.

Headlining the 2026 program are UK deep house favourite Harrison BDP, genre-bending Swedish producer DJ Seinfeld, Netherlands house selector Suze Ijó, and Berlin-based Japanese artist Alex Kassian. On the local front, the bill features the highly anticipated debut of RONA., alongside established favourites Roza Terenzi, Pretty Girl (Live), Kia, and Sam Alfred. Also announced are Voigtmann, Elsie Craig, Wallace & Malone, Tory Kennedy and Musch.

In a festival first for Australia, Sidebyside will introduce a time-based ticketing system designed to encourage early arrival and support for opening artists. Attendees can choose between General Admission before 3:00 pm and General Admission Anytime tickets—rewarding early birds with cheaper prices and better access.

Now in its sixth year, Sidebyside continues to blend music, art and community in Adelaide’s scenic city parklands. Alongside the music, punters can expect large-scale art installations, stage design collaborations, curated lighting, and local food and drink options—including limited-edition canned cocktails in partnership with Pluto Spirits.
