Western Sydney International Airport opens October 8, 2026. The 24-hour operation challenges Kingsford Smith's slot constraints and curfew. Qantas and Jetstar are anchor carriers. Initial capacity is 10 million passengers annually.
Western Sydney International Airport has a firm opening date. The first commercial flight will depart on October 8, 2026, the airport's CEO said in a statement. The project has been in planning for more than 40 years.
The airport sits in Badgerys Creek, about 45 kilometers west of the Sydney CBD. It is designed to relieve pressure on Kingsford Smith Airport, which has operated at near-capacity for years. Sydney's two-airport system has been debated since the 1940s. A 2014 federal government decision finally locked in the site.
Kingsford Smith handles roughly 44 million passengers a year. Its curfew runs from 11 p.m. to 6 a.m., and its slot system is among the tightest in the Asia-Pacific region. Western Sydney International will operate 24 hours a day with no curfew. That alone shifts the competitive dynamic for airlines flying long-haul routes into and out of Australia.
The airport's initial capacity is set at 10 million passengers annually. Stage one includes a single runway and a terminal designed for both domestic and international traffic. The CEO said the airport expects to serve 5 million passengers in its first full year of operation.
Qantas and Jetstar have already signed on as anchor carriers. Qantas will base A220 and A321XLR aircraft at the airport for domestic and short-haul international routes. Virgin Australia has not yet committed to a base. It said it will operate flights from the airport.
The open question is which international carriers follow. The 24-hour operation makes the airport attractive for cargo operators and for passenger airlines that want late-night departures or early-morning arrivals. Freight operators including DHL and FedEx have already secured space in the cargo precinct.
Kingsford Smith's slot constraints have pushed up landing fees and limited growth for budget carriers. Western Sydney International's pricing structure has not been fully disclosed. The airport has signaled it will keep charges competitive to attract volume. The CEO said the airport's cost base is lower than Kingsford Smith's because it is a greenfield site with modern infrastructure.
For travelers in western Sydney, the airport cuts drive time to a terminal by roughly an hour compared with the trip to Kingsford Smith. The catchment area covers about 2 million people.
Three milestones matter between now and the opening. First, the final runway certification from the Civil Aviation Safety Authority, expected in mid-2026. Second, the airline slot allocation process, which will reveal which routes get priority. Third, the transport links: a new metro line connecting the airport to the Sydney rail network is not scheduled to open until 2028. Early passenger traffic will depend on road access and bus services.
The airport's opening date is fixed. The question is how quickly airlines fill the schedule and whether the 24-hour operation changes route economics for long-haul carriers that previously had to work around Kingsford Smith's curfew.
