Do you have any idea how much people in the west spend in tolls, parking, fuel and time to/from mascot? I think the biggest problem for the people of the west is to get over the mindset that the airport is in the city and make sure they book and show up at the correct airport
Yes - I'm one of them... and currently I'd still prefer SYD to WSI.
I still have to pay tolls, parking, fuel, and waste time in traffic to/from WSI. In fact, with WestConnex it's effectively the same time from home to SYD as it is from home to WSI, give or take five mins. Basically, if I chuck a left I get to one, chuck a right I get to the other.
At least with SYD, I also have easy bus and train access - within walking distance with a suitcase - to get to the CBD and connect with Airport trains. WSI has none of that (and won't for a very long time).
Ordinarily I'd say I'm in the minority, but I've seen lots of coverage of locals much closer to the airport complaining that their access to the airport is limited, with an over-reliance on car travel on congested roads (toll and non-toll), and public transport bordering on dysfunctional.
I imagine lots of westies will take advantage of a Sydney West airport for their kids holidays or long weekends, sporting trips etc, especially once public transport is improved for access.
Unlikely to happen with cough, infrequent buses for the first two years, and cough trains that go nowhere sometime this decade.
If they still have to get in the car and pay tolls/petrol/parking, then it's probably easier to keep going to Mascot, where all the airlines fly to/from with frequencies, timings, and connections that are far more convenient.
Yes, some Westies will take advantage of Badgerys Creek, but I suspect it won't be nearly as many as expected for a long time.
