A power outage at Perth Airport on 29 October 2026 caused significant disruptions to flight operations. Key systems, including check-in and security screening, were affected, leading to delays and cancellations. Airlines including Qantas, Virgin Australia, and Jetstar had to adjust schedules, with some flights departing late or being cancelled.

Passengers faced missed connections and extended waits for rebooked flights as operations slowly recovered. The outage occurred during severe weather, including strong winds and heavy rain, which compounded the challenges for airport staff and airlines. Backup systems were activated, but they were unable to fully prevent the disruption to passenger processing and flight operations.

The incident has prompted a review of Perth Airport's backup generation and resilience measures, as the vulnerability of aviation infrastructure to extreme weather and grid failures comes under scrutiny.
