Australia's most populous city opens $4B international airport to passengers

Sydney's new A$5.6 billion ($3.94 billion) airport opened to passengers on Sunday after more than a decade ​of planning, in what Prime Minister Anthony Albanese ‌said was a milestone for the country's most populous city.

The new Western Sydney International Airport in Badgerys Creek, about 60 km (37.3 miles) west of central Sydney, will operate 24 hours a day, giving airlines access to a fast-growing and ⁠ethnically diverse population center.

The current airport, located closer to Sydney's central business district, can host takeoffs and landings only until 11 p.m. and after 6 a.m., limiting airline scheduling options relative to other major Australian cities like Melbourne.

"For the first time in more than 50 years, Australia is opening a major new airport. It’s a milestone that has been decades ‌in ⁠the making," Albanese said in a statement.

"I’m very proud to officially open it," he said.

Qantas' budget arm Jetstar was due to operate the first outbound flight to the Gold Coast on Sunday, the ⁠airport said in a statement. The airport has capacity for more than 80 million passenger movements annually, it said.

The start of passenger services ⁠comes after cargo flights commenced at the facility in July.

Located on a 1,780-hectare (4,398-acre) site purchased by the federal government ⁠in the 1980s, the airport was completed in July 2025 after a seven-year build and 15 years of planning.
