Western Sydney Airport (WSI), With 24/7 Flights, Opening Late October 2026

Given the lack of direct rail links and distance to the CBD I imagine this will mostly be a lower cost airport?
I get that car rides will quick during the curfew but it would seem odd to split operations for airlines that are aiming for business travellers the rest of the time.

I'm honestly surprised that Sydney with a metro population of only 5.6M needs a second airport. SYD itself only handles 42M passengers a year. Certainly the curfew affects capacity, but there are cities with larger populations than that, which don't require a second airport.

The issue isn't really that SYD needs more capacity, but there's a significant bottleneck in capacity at specific peak hours.

Flew over this airport on a flight from SYD-ADL last year while it was still under construction. Looked nice from the air!

I don't think the 24/7 operating hours will be of much interest to Gulf carriers. They all have evening departures from SYD (as well as most other major airports) around 9/10 p.m. each night, which arrive into their Gulf hubs around 5 or 6 a.m. the next morning.

This connects perfectly to their banks of European departures at 8 and 9 a.m.

Stupid.

This project and supporting infrastructures are estimated to cost almost $20 billion.

Might as well just abolish the stupid SYD curfew and use that money to pay NIMBY snowflakes to move away.

Problem solved. Money saved.

You'd think extending the SYD curfew to 12 midnight would largely negate the need for a second airport.

Not stupid. Jobs. This creates more slots. Problem solved a better way. Money grown.

I expect WSI will heavily lobby international LCCs like Air Asia X, Malindo, Scoot and Cebu Pacific to switch from SYD to WSI via much lower landing and airport fees.

If that works, it can then start with the less prestigious Chinese carriers, such as Juneyao and Beijing Capital.

Yes, Rain, I think at least initially it will be more of a lower cost hub. Kingsford Smith is insanely close to Sydney's city centre - it's just 10 minutes by train - so most premium travel will still be to there. But there are millions of people in Sydney's west and it will be convenient for people from regional areas who don't want to battle Sydney traffic. Also Parramatta, a growing business district, is relatively close to the airport. So low cost, yes, but with a modicum of premium too. I can see flights to New Zealand, Fiji and Bali doing particularly well. The other factor is cargo as curfew free WSI will be very close to the wall of distribution centres and industry on Sydney's western edge.

Funny. I booked a flight from Sydney to Bangkok via Singapore in March of next year via Aeroplan. I didn't notice it was from WSI (the AC site just had an error code for the city name). They had good availability and it was only 45,000 in Business (booked it before the Aeroplan increase). Getting to the airport seems like it will be a pain, but still happy to book this ticket at this cost.

I can’t see an extension of the Kingsford Smith curfew happening. Hundreds of thousands of people, maybe a million, live under the flight path enough for it to disturb. For residents of inner Sydney, every night every few minutes you have to pause or turn up the volume on the TV and that’s with the curfew kicking in at 11pm. My alarm clock at 6am every morning was an Emirates A380 landing from Dubai. That’s the compromise of being near the airport and the city. But Having the airport encroach even further into Sydneysiders’s sleep would be untenable.

Stupid argument.

You can build a 2000 ft. Trump statue.
Jobs. This creates more jobs. Problem solved a better way. Money grown.

Weak retort. False equivalence. Completely irrelevant example.

Niiice on those flights! By car, WSI is a 60+ minutes away, depending on traffic (nothing like CBD to SYD in just 15 minutes). Only transit option is buses, until they open the new Metro line, delayed to 2027 (and it'll only connect WSI to St Marys). But, lie-flat for just 45k, I'd say, that's still worth it!

WSI would have fit my needs just fine! Most of my wife's friends in Sydney live precisely in these outer western suburbs, and sights like the Blue Mountains are closer. Sydney Airport may be convenient to get up to the Opera House, but it takes a couple of hours to get where my family needed to be, as learned when we went two months ago.

There are numerous suburbs with tens of thousands of people and thousands of houses near the airport. So, where are they going to move to?

Meanwhile, 80 years on, the Brits are still fighting about a possible third runway at Heathrow.

Explorer, look on a map of NSW; think, DEN after Stapleton (for a US-based example); besides, airport was already there; not much around it. May even be a boon to those local communities (jobs!)

Don't be fooled, it's taken more than 35 years to get WSI built and operational. Did they do the job properly, with four runways and terminal capacity for 50M pax per annum? No, of course not, because this is Australia, where governments so things in a half-assed, piecemeal fashion. Why spend the money now when you can spend the next 50 years rebuilding and extending?

WSI will certainly have pax, there's no doubt, but SYD won't go out of business either. In general terms, the most frequent air travellers live in the eastern suburbs, or on the north shore. They're also the wealthiest, by a wide margin. Sydney can definitely support two airports.

*correction, airport NOT already there.

I agree a 2000 ft. Trump statue is false equivalence.

But I need to dumb down the example so you can understand. Even your latter claiming it's irrelevant already shows you're too dumb to understand.

Ah yes PeteAU. Build a huge white elephant before the demand is actually there. Lol.

Will Delta serve it nonstop from ATL?

I suspect it will be equivalent of Washington Dulles when it opened in 1962. Far out airport, with limited fights and took a long time to get going with large capacity. It will take WSI 20 years to be significant.

Coming from someone that lives nearby, I hope this isn't the answer.

And yes I moved in after the airport was operating before anyone cleverly asks.

“Build it, and they will come.”

An indirect transit connection can work, if done well. To get to Changi airport, pax from central Singapore need to change trains en route but, in both direction, the interchange is just cross-platform.

Nobody cares.

But virginatlantic.com they can leave around 1am 2am, they can arrive at lunchtime take the European passengers and return on the kangaroo timings on the way back

Don't know what happened there but yes they can time it better for the traditional kangaroo customers away from qantas. In fact if they can get from WSI to the CBD in less than 3 hours it might just work

Or, like Idlewild Airport, back in the day... now known as JFK.

Yeah, similarly situation in NYC (A/E subway to JFK's AirTrain), as in many other cities. It can be done; whether it's done well or not is another story. Fingers crossed!

the way i look at it, SYD will be largely used by tourists and this new airport would serve the local resident population

This is NSW's version of Ontario Airport in California

Or Ontario CA

I wouldn't use it for a stay in Sydney because of the transportation options. I imagine it would be better than SYD for an international to inter-Australian flight as it has just the one terminal (not the separate, unconnected terminals at SYD). I used to stay in Sydney on every trip to Australia, but I stopped a couple of years ago. Sydney has just so much more expensive hotels than other capital cities.

Strong disagree. The most frequent and wealthy travellers in Sydney live in the eastern suburbs and the north shore/northern beaches. Those are the pax who buy the bulk of the premium cabin tickets that makes SYD such a high-yielding airport for most airlines. WSI will certainly be able to fill the seats, but it will never compete with SYD in terms of the sheer numbet of well-heeled premium-cabin travellers who live within a 45 minute drive of the airport.
