One of the Southern Hemisphere’s most anticipated annual cultural events, Vivid Sydney, hit an unexpected snag on the evening of Monday 25 May local time, when nearly 90 drones plummeted from the night sky over Darling Harbour during the festival’s popular Star-Bound aerial display. Witness footage captured the dozens of unmanned devices tumbling out of formation, with many splashing into the waters of Cockle Bay just a short distance from gathered onlookers, leaving crowds confused by the sudden disruption to the programmed light show. The incident has already forced the cancellation of two scheduled performances, with the future of the remaining 20 planned drone shows still under review. The UK-based drone production company Skymagic, which designed and operates the 1,000-drone display, has pinpointed the root of the failure: an unanticipated shift in radio frequency conditions that occurred after the drones had already taken off. According to a company spokesperson, the frequency change disrupted positional accuracy for affected devices, triggering their pre-programmed failsafe landing protocols that sent them descending into the harbour and surrounding marina areas. Skymagic was quick to emphasize that no drones fell outside the designated safety boundaries set for the performance, meaning no bystanders were injured in the incident. That claim did little to soften the shock of witnesses, however. Robert, a worker at the Darling Harbour waterfront, told Australian public broadcaster ABC that the sound of crashing drones was audible even from 10 to 20 meters away. “You could hear them physically crash and smash onto the cement marina,” he explained. Representatives for Vivid Sydney, the three-week long festival that draws hundreds of thousands of locals and tourists to Sydney Harbour and central Sydney every year, issued a formal apology for the disruption. “We apologize for the disappointment and inconvenience caused to attendees,” the spokesperson said, adding that the decision to cancel upcoming performances aligned with the event’s standard safety protocols. Festival organizers have confirmed that Skymagic will partner with relevant Australian government agencies to conduct a full technical review of the incident. No decision will be made on whether to resume the remaining drone performances until the assessment is complete. The Star-Bound drone display was scheduled to run over 11 nights, with 22 total shows planned as a key attraction for the 2026 festival. This year marks only the second time Vivid Sydney has included drone shows in its official lineup: the festival first introduced aerial drone displays in 2024, drawing massive crowds, but opted to cancel all drone shows in 2025 over public safety concerns related to overcrowding. First launched in 2009, Vivid Sydney brands itself as the Southern Hemisphere’s largest combined festival of light, music, ideas and food. The event’s core attraction is a free 6.5-kilometer walking trail dotted with 43 large-scale light installations, including iconic light projections mapped onto the sails of the Sydney Opera House. Annually, thousands of visitors from across Australia and around the world travel to Sydney to attend the three-week winter festival.
