SQ201 looks appealing with its 11:30am departure, just like SQ217 to MEL, however worth considering it touches down in Sydney at 10:30pm - add the time it takes to clear immigration, you’re out by maybe just after 11pm and then consider how long it’ll take to get home if you don’t live in Western Sydney, unless you splurge on an Uber or have someone to pick you up.
This. WSI is 72km from my home cf to Syd which is 22km. I can get a Didi to / from Syd for less than $50 most times. With no (likely expensive) fast train yet at opening, and the only public transport option is a bus from / to St Mary's train station, given Uber / Didi fares are likely to be $100+ oneway, I don't think I will be using WSI moving forwards. If I lived in Western Sydney, another story...
Just looked it up:
Public transport to Western Sydney International (WSI) Airport (opening late 2026) will feature a dedicated, free 30-minute shuttle bus from St Marys train and bus interchange. This service runs 7 days a week, connecting to the T1 Western Line. Additionally, five new regional bus routes will launch early to connect areas including Penrith, Liverpool, and Mt Druitt to the airport.
Key Transport Options (from late 2026):
WSI Link (Free Bus): Connects St Marys to the airport in ~30 mins.
New Regional Buses: Routes 790 (Penrith), 845 (Campbelltown), 825/860 (Liverpool), and 772 (Mt Druitt) will serve the airport.
Sydney Metro (2027): A new 23km Metro line will replace the interim bus service, providing fast rail access directly to the terminal, linking to St Marys in just 15 minutes.
Operating Times: Initial shuttle buses will run from approximately 4:30 AM to midnight (Sun-Thu) and 1:00 AM (Fri-Sat).
Infrastructure: The airport is connected to the M12 motorway, supporting buses, taxis, and rideshare
