Mayday 2.0 is a single-day old skool rave event returning by popular demand after selling out in 2025, hosted at the iconic Adelaide Gaol on 2 May 2026 from 4 PM to 11 PM. The event features three stages—Main, Trance, and DnB—with an all-new lineup of OG pioneers, Australia's recognized DJs and music producers, and top local Adelaide talent playing classic 90s and early 2000s club anthems. Attendees are encouraged to dress in old skool rave style with fluffies, glow sticks, neon colors, and bum bags. It's an 18+ outdoor event with limited capacity, VIP options for priority access, and food vendors on site. Exact stage programs will be released closer to the date.
