Key Notes
- Western Sydney International opened to passengers on October 25 with Jetstar’s Gold Coast departure.
- Air New Zealand’s Auckland service is scheduled for October 26 and Singapore Airlines follows on November 23.
- WSI is separate from Sydney Kingsford Smith and the free St Marys bus operates while its Metro connection is under construction.
Western Sydney International Airport opened to passengers on October 25, giving Australia’s largest city a second major gateway and a new round-the-clock alternative. Jetstar flight JQ362 to the Gold Coast became the airport’s first commercial passenger departure, starting a network that will expand in stages.
The opening follows decades of planning for the Badgerys Creek site. The Australian Government’s opening statement describes a terminal serving domestic and international passengers under one roof, with more than 40 check-in kiosks and 34 bag-drop kiosks. For travelers, the immediate change is another airport to consider when searching for Sydney flights.
Which Flights Are Starting First?
Jetstar, part of the Qantas Group, is the first domestic passenger airline at the new airport. International services follow separately. The government’s published schedule sets out the initial sequence:
- Jetstar: the Gold Coast service began on October 25, with Melbourne also on the opening-day schedule and Brisbane part of the initial domestic network.
- Air New Zealand: Auckland flights are scheduled to begin on October 26, making the airline the first international passenger operator.
- Singapore Airlines: daily Singapore flights are planned from November 23, adding onward travel through Changi.
Those dates describe a phased opening, not a full international network operating from the first day. Check the airline’s actual timetable for the route and travel date you want. An announced airport partnership does not mean every service has started.
We previously covered Singapore Airlines’ expansion at Western Sydney. Its November launch is part of the airport’s next stage; Air New Zealand’s Auckland service comes first in the current opening schedule.
Check the Airport Code Before Booking
The new airport uses WSI. Sydney Kingsford Smith, the established airport at Mascot, uses SYD. They are separate airports, so check the three-letter code on both your outbound and return flights before arranging parking, transfers or accommodation.
This is especially important if a booking combines different airlines or separate tickets. A Sydney arrival and departure are not necessarily in the same place. If an itinerary switches between WSI and SYD, allow for a road transfer rather than treating it as a change of terminal.
How to Reach WSI Before the Metro Opens
The airport’s rail link is not open with the terminal. For now, Transport for NSW’s WSI Link provides a free bus connection between St Marys Station and the airport while the Metro remains under construction.
Buses run every 30 minutes from 4:30am to midnight, Sunday to Thursday, and from 4:30am to 1am on Friday and Saturday. The service uses Nariel Street at St Marys and Stand A at WSI, with luggage storage and wheelchair access. The free fare applies to WSI Link; do not assume it makes the rest of a public-transport journey free.
The airport’s transport guide also lists taxis, rideshare, parking and road access via the toll-free M12. The Metro connection is planned for 2027. Until it opens, build the bus connection and any onward train travel into your journey rather than expecting a direct airport rail service.
What the New Gateway Means for Your Trip
A 24-hour airport gives airlines more flexibility in scheduling and offers another starting point for western Sydney travelers. Its usefulness for an individual trip, however, depends on where you are staying, which flights are operating and how you will reach the terminal.
Compare the flight price with transfer time, transport costs and the departure hour. The airport can operate overnight, but the free bus does not run all night. A convenient fare is most useful when the journey to and from the airport works just as well.
