From November 23, Singapore Airlines' new daily flight to Western Sydney International is due at 10:20 p.m. By that hour the five regular bus routes serving the airport have stopped for the day, and on Sunday to Thursday nights the free shuttle to St Marys station runs only until midnight. Sydney's new airport opens to passengers on Sunday, October 25, before the metro line built to reach it, and that late flight is where the margin gets thin.
The "no train" part is true, and the state says so plainly. Transport for NSW's page on getting to the airport, as I read it on October 10, states: "There are no direct train services to Western Sydney International Airport (WSI)." The metro line from St Marys through the airport to Bradfield, where the government plans a new business district, has all its track laid, according to a June 11 NSW Government release. The trade magazine Australian Aviation reported in June that the line had been "pushed back to at least 2027," and that a dispute with contractors could delay it further. I could not find an official opening date on any government page I checked.
Five bus routes, one free shuttle and a paid express
There are more ways in than the free shuttle. Transport for NSW's airport page, as of October 10, lists the public ones. The free WSI Link bus will run between St Marys station, on Sydney's main western rail line, and the terminal every 30 minutes, from 4:30 a.m. to midnight Sunday to Thursday and until 1 a.m. on Friday and Saturday. The government puts the ride at about 30 minutes in normal traffic and calls the service temporary, running "until Sydney Metro services start."
Five regular routes have run since July from four western Sydney hubs, Penrith, Mount Druitt, Campbelltown and Liverpool, which gets two routes, every 30 minutes from 5 a.m. to 10 p.m. daily. A 2025 Transport for NSW newsletter puts the scheduled rides at 55 to 67 minutes.
For a price, there is Super Shuttle WSI, a private express. Its booking page, last updated September 28, lists adult one-way launch fares of A$25 to Parramatta's business district, $55 to central Sydney and $65 to Sydney's existing airport. Neither its home page nor its booking page showed a timetable when I checked on October 10; the home page says "Departure times matched to the WSI flight schedule." Taxis run on the meter with no fixed fare unless pre-booked. Rideshare will have pick-up zones outside the terminal, and the toll-free M12 motorway runs to the airport.
The margin thins at night, not at dawn
Western Sydney International's chief executive, Simon Hickey, pitches the airport's "24-hour capacity," as he did when Singapore Airlines announced its daily flight. The morning looks fine: Air New Zealand's three-a-week Auckland service, from October 26, is scheduled to land just before 8 a.m., well inside bus hours.
The Singapore flight is another matter. As scheduled in the airline's announcement, the first one is due on a Monday, under the Sunday-to-Thursday hours, at 10:20 p.m. That leaves at most an hour and 40 minutes before the free shuttle stops running, with immigration and bags still to clear, and a delayed flight or a slow queue eats into it. A bus leaving near midnight reaches St Marys around 12:30 a.m., by which time, Transport for NSW says, NightRide buses have replaced Sydney trains for the night. Miss the last free bus, and the realistic choices are the private shuttle, if one is timed to your flight, or a taxi or rideshare.
The government says St Marys "will become a major transport hub connecting metro, suburban rail and bus services." For now it is where a late arrival changes buses. Until a train runs, check two things before you book: the time you land, and the day of the week.
