I know the ABS SUA includes the Blue Mountians, but I don't consider the Blue Mountains part of Sydney, so Emu Plains would be in Sydney but Lapstone not.
ABS Boundaries aren't administrative boundaries, rather just ABS's view for statistical reporting.
It's hard since you can't survey this on the ground, I'm not aware of any official source, so the best approach is really to consider what do most people consider part of Sydney.
What do you think?

...aware that @TheSwavu also replied with a direct message. But worth noting that on the way down from the Blue Mountains there is a sign which says "Welcome to Sydney", which would indicate that the Blue Mountains shouldn't be part of Sydney.
I'm torn though, @TheSawvu raised good argements for including Blue Mountains in Sydney. At the end of the day anyone can always create the own polygons including or excluding if they want.

Yeap, I've seen the same style sign on the Hume. They line up with the NSW tourism regions:

I guess if that's what admin_level 7 should be then we need to change the definition.
I was thinking that if you really don't like this definition of level 7 then we could change this to boundary=statistical stats_level=SUA. I find this type of boundary useful as I don't have the wherewithal to run my own spatial database but I can use these in Overpass.

I don't have a strong opinion either way. Just chiming in with further facts from the ground to help guide what should be in OSM. Even if we did split the Blue Mountains out, You should be able to include both the Blue Mountains and Sydney in overpass together.
