For as long as most Sydneysiders can remember, the city’s air traffic has run into a wall every night. Kingsford Smith Airport — Sydney’s only major gateway — shuts to most aircraft between 11pm and 6am under a hard legal curfew. After dark, one of the busiest aviation markets in the Asia-Pacific simply goes quiet.

That changes on 25 October 2026. On that day, Western Sydney International — formally the Nancy-Bird Walton Airport, named after the pioneering Australian aviator — opens to passengers as the city’s second major airport. And unlike its older sibling, it never closes.

A Gateway That Never Sleeps

The headline feature isn’t the size — Stage 1 handles a modest 10 million passengers a year, growing toward 37 million by mid-century. It’s the clock. Western Sydney is designed to run 24 hours a day with no overnight curfew, the thing Kingsford Smith has never been able to offer. A new Sydney Metro line is being built to carry passengers straight out to Badgerys Creek.

That single difference reshapes what airlines can do. A curfew-free airport unlocks late-night and red-eye schedules that are impossible at Kingsford Smith — which is exactly why Singapore Airlines plans a daily Airbus A350-900 service to Singapore from 23 November 2026, built around a late departure the old airport could never accommodate.

Why a Second Airport, and Why Now

Kingsford Smith is boxed in. It sits in the heart of the city, surrounded by suburbs and water, with little room to grow and a curfew that protects residents’ sleep at the cost of capacity. As Sydney’s population pushed west, the case for a second airport closer to the growth — and free of the night-time shackles — became overwhelming.

Western Sydney is the answer: a greenfield airport with room to expand to a second parallel runway when demand demands it, positioned in the fast-growing west rather than the crowded east.

First Through the Doors

Freight flights begin on 27 July 2026, with passenger services following on 25 October. Jetstar takes the honour of the first passenger flight, to the Gold Coast, on opening day; Air New Zealand starts services to Auckland the next morning; and Singapore Airlines opens the international long-haul account in November.

For a city that has spent decades planning, arguing over and finally building its second airport, the symbolism is hard to miss. When the lights stay on past midnight at Badgerys Creek, Sydney will have done something it never could before: keep flying around the clock.
