In Sydney, it's generally the case for established neighbourhoods close to the CBD. Walkability in inner city suburbs like Balmain, Leichhardt, Rozelle, any of the eastern suburbs really is super high.
Contrast this to urban-sprawl created suburbs like Marsden Park and a few of the Hills district burbs and it's the opposite - barely any public transport and next to no community infrastructure.
So how then do you know that Spain will veto a Scottish application to rejoin? Have Spain produced a more up to date statement changing their position? If not, then are you not just spreading FUD?
edit: Also, Johnson shutting down the possibility of a second independence referendum is not the be all and end all: the Scottish government could pass legislation for one without a section 30, which would likely be challenged in court by the UK government. If the supreme court upholds the right for Scots to vote in a referendum, then it goes ahead.
To your last point: have Spain changed their position since they said they would not veto a Scottish application to rejoin [1]? I haven’t seen anything to suggest they have.

There's a good channel on YT that documents this sort of stuff here: https://www.youtube.com/watch?v=JDhbm-t3dXU
