Hi Graeme
I’m not sure I can offer any advice on tagging but I’ve worked in land
administration and can offer some general guidance on the hierarchy of land
classification. My knowledge is mostly Queensland based but I believe all of
the states have a similar system given that ultimate authority over land is
federal. The nested hierarchy is simply Country>State>LGA>suburb (or
locality)>parcel. That is parcels comprise suburbs, suburbs comprise LGAs and
LGAs comprise states so there is a complete coverage or fabric over the land
and inshore areas. The regions mentioned will most likely not have any admin
status unless they are associated with an act of legislation (such as South
East Queensland which now has defined boundary of the common participating
councils). There may be other areas such as Parishes or Counties which are
still used in legal titles but these are largely no longer used for anything
other than that due to the fact they were drawn up in an age which predates
most modern systems and in a time where the local Church as something people
recognised as a centre of an area.
Maybe someone working with cadastral fabrics in the states can provide more
detail if required.
Kind Regards

I looked at the Wiki. It is quite a while since I looked at the section on
administrative boundaries. My recollection is that it used to have LGA as
admin_level=6 and suburb as level 9 or 10. I do not recall any discussion of
inclusion of regions, districts and townsites nor any previous discussion in
regard to changing the level of LGA. The wiki includes a link to a
downloadable example which is headed "Australian Boundary Tagging _ OSM" but
with copyright attributed to Government of Western Australia. I am not sure
how the current content of wiki was arrived at. My memory is not perfect so
perhaps someone can remind me how the wiki content on administrative boundaries
and the WA Government copyright document was reached.
In NSW there are land districts defined in legislation with administrative
boards etc so they could be included if we could get permission to use the
source data (not included in current approval as far as I am aware) and there
are probably equivalents in other jurisdictions. I think administrative
boundaries must be sourced from government. In NSW, land districts are
larger in area than local government areas (LGAs) but their influence and
importance is (in my view) much less than LGAs - the Greater Sydney Local Land
Services board has the majority of its membership appointed by the Minister for
Agriculture and few Sydney residents would even know of its existence or role.
I'd want to put them at level 11, certainly not a higher level than the LGAs.
I do not think that a larger area automatically warrants a higher
administrative level.
I am open to changing and developing our guidelines. However some boundaries
are not necessarily administrative e.g. Eyre Peninsula (natural region),
Barossa Valley District (protected area), Illawarra Region, New England Region.
Some boundaries might be tourist labels or have local currency but would need
to be mapped as something other than administrative.
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, C
