Australia airport alert · Updated 16 October 2026
Passengers departing Sydney Airport on Friday, 16 October, face longer security queues during two planned industrial-action windows: 6:00–10:00 and 17:00–21:00 local time. Screening is expected to continue at reduced capacity, while several airlines have issued special guidance or flexible-change options.
What passengers should expect
The action concerns some security-screening staff rather than pilots or air-traffic control. That distinction matters: the immediate risk is a slower passage through screening, followed by possible departure delays if passengers and crews cannot reach gates normally. Qantas, THAI and other operators have advised travelers to allow extra time.
How early to arrive
Follow the airline’s own check-in recommendation and add a strike margin. International passengers should complete check-in and move directly to security rather than waiting landside. THAI said its counters for flight TG476 would open at 07:30 for an 11:00 departure, illustrating how airlines may adjust handling. Travelers with checked luggage should still respect bag-drop opening and closing times.
Qantas and eligible changes
Qantas said eligible customers departing on 16 October could move to another flight under its published conditions. Eligibility depends on the operating carrier, terminal, ticket and booking date, so do not assume every itinerary qualifies. Use Manage Booking or the original agent and obtain written confirmation before leaving the original flight.
International connections
A long security queue can damage an onward connection even when the first flight departs. Check minimum connection time, especially on separate tickets. Keep medicines, documents and essential items in cabin baggage, but pack correctly so prohibited items or misplaced power banks do not create an additional screening delay.
After the strike window
Queues may not disappear at the exact end time because a backlog can remain. Continue monitoring the airport and airline until boarding. If the airline cancels or materially changes the flight, ask about rebooking or credit before purchasing a replacement. The strike notice alone does not confirm that a particular flight is cancelled.
