Public trials with participants acting as passengers are planned to begin in April to test facilities and the overall passenger experience.

WSI will operate as a full-scale, curfew-free international, domestic, and freight airport, while Bankstown Airport continues to serve light aviation, manufacturing, and logistics.

Western Sydney International Airport (WSI) is nearing its opening, with first passenger flights planned for October 2026 and cargo services starting in July, as four major launch partners—Qantas, Singapore Airlines, Air New Zealand, and Jetstar—prepare for international operations before year-end 2026 and substantial capacity growth by 2030.

Jetstar and Qantas domestic and international routes from WSI will be announced in due course, with freighter operations slated to begin from the airport mid-year.

The airport will employ a high-efficiency baggage system featuring a Vanderlande robot-powered setup and unified self-service kiosks and bag drops, alongside a dedicated fire station and ongoing retail and F&B fit-out to enhance passenger flow.

WSI is expected to relieve congestion at Kingsford Smith Airport and boost Western Sydney’s economy, creating tens of thousands of jobs across aviation, logistics, retail, tourism, and education.

The opening timeline is affected by a delay in the $12 billion metro link to the Sydney Trains network at St Marys, now potentially pushed to December 2027.

Accessibility to WSI will improve as travel times from western Sydney centers shrink—Penrith approximately 25 minutes, Parramatta about 35 minutes, and Bankstown around 40 minutes.

Key infrastructure supporting WSI includes the new M12 Motorway opening in 2026 and the $12 billion Sydney Metro–Western Sydney Airport line, slated to open in 2027, with interim free bus services available until the Metro is completed.

The project represents roughly $6 billion in investment, with the terminal nearing completion and flight-paths and system testing underway after more than a decade of planning.

A $16 million government-backed incentive fund will support international airlines flying to WSI, benefiting Air New Zealand and Singapore Airlines.

WSI forecasts around 8.4 million passengers annually by 2030 and 19.3 million by 2045, while Mascot Airport is planning growth to about 72 million passengers annually by 2045.
