Sorry I'm getting offtopic here... I'm only familiar with NSW but for example we have a few non-administrative regions/districts mapped Illawarra https://www.openstreetmap.org/relation/7876497 tagged as place=region without an admin_level Northern Beaches https://www.openstreetmap.org/relation/7876483 tagged as place=district without an admin_level Lower North Shore https://www.openstreetmap.org/relation/7876484 tagged as place=district without an admin_level Upper North Shore https://www.openstreetmap.org/relation/11373192 tagged as place=district without an admin_level St George https://www.openstreetmap.org/relation/7876480 tagged as place=district without an admin_level others could be added like The Shire, South Coast, Hunter Valley, Central Coast, Hills District, Eastern Suburbs, Blue Mountains + regional regions/districts. I agree that these are not administrative boundaries so I'm fine with not giving them an admin_level, and it's a fair argument that these are not verifiable on the ground, but nonetheless they do exist and people refer to them frequently in conversation. In terms of the admin_level for LGA's I think if we have administrative regions or not shouldn't really affect the admin_level value too much, I think going with what most other countries use for
