Western Sydney International Airport will take its first flight on 25 October 2026, backed by A$5.3bn ($3.5bn) in Australian government funding and an initial fleet of 15 Qantas Group aircraft, with Singapore Airlines and Air New Zealand to follow within weeks. The airport, also known as Nancy-Bird Walton Airport, sits on a 1,780-hectare greenfield site at Badgerys Creek with a single 3.7-kilometre runway and an initial annual capacity of roughly 10 million passengers, operating without the night curfew that constrains Sydney Kingsford Smith.
The based-aircraft commitment at launch is modest by design: 10 Jetstar aircraft and five Qantas jets, both under the Qantas Group banner, which becomes the airport’s sole confirmed based-aircraft operator. Virgin Australia signed an early memorandum of understanding on design input back in 2019 but never converted that into a based-fleet commitment, leaving the airport’s longer-term carrier mix still open.
International services arrive fast behind the opening. Jetstar flies the inaugural commercial departure to the Gold Coast at 11am on 25 October, Air New Zealand starts Auckland flights the following day, and Singapore Airlines begins daily Singapore services from 23 November 2026, giving the airport a confirmed international network that extends well beyond its launch fleet.
Freight is already running: cargo operations began in July 2026, ahead of the passenger opening, with Qantas Freight and ground handler Menzies Aviation signed as the airport’s main cargo partners. Menzies has been expanding its own contracted footprint elsewhere too, most recently adding passenger handling at Kuala Lumpur after a licence win, and the Western Sydney cargo precinct gives it another long-term base to build volume from.
Owner and delivery body WSA Co Limited puts the total project cost at approximately A$5.3bn, with the Australian government as sponsor and funder and oversight sitting with the federal transport department. Construction, which began in September 2018, has supported more than 12,800 jobs (roughly half going to local workers) and over $500 million invested across 360 Western Sydney businesses, according to government figures cited by Construction Review Online.
For readers running or financing capacity programmes elsewhere, the structure is the interesting part, not the headline figure. The airport has been built to the scale its 2025-2045 master plan sets out, well ahead of the confirmed traffic to fill it, a pattern also visible in Birmingham’s own £2bn master plan targeting 30 million passengers. It is the same logic ACI World pressed governments on when it put the global capacity shortfall at $4 trillion: build and fund the infrastructure first, then negotiate the airline mix. Private capital is doing the equivalent job on smaller UK programmes, as with VINCI Airports’ £500m, five-year pledge for Edinburgh.
This is reported from the announcement by Construction Review Online, which carries the full project fact sheet and construction timeline.
For airport executives watching the file, the number to track from here is not the $3.5bn build cost, which is now fixed, but how quickly the carrier list grows beyond the initial 15 aircraft against a runway and terminal sized for 10 million passengers a year.
