In regard to smaller rural centres, I have also been wondering about
classifications. In South Australia, some rural properties constitute
their own official location with their own allocated postcode. In one
case the farm is known as "Oakvale" but the official Government-approved
name for the location with defined boundaries and its own allocated
postcode is "Oakvale Station". I had originally labelled it as
place=farm but the OSM WIki says that if the farm is not part of a
larger settlement, then it should be labelled as "isolated_dwelling".
Since it is its own suburb and not part of a larger settlement, I have
labelled it as place=isolated_dwelling.
 
"Hamlet" can be a small population but does not necessarily have a
central location- thus Mossgiel in NSW has a defined area and postcode
with scattered farms in the area but there is no centre with shops or
services - thus it is tagged as place=hamlet. Once a place has shops,
pub, other services etc. I think it qualifies as a "village".  But two
places could be villages even though one is a fair bit larger than the
other - if you can get food and fuel etc. but it's not big enough to be
a town, then "village" is a good classification.
 
In NSW, "city" is an official Local Government Area status approved by
Government so that some larger towns (and their surrounding areas) are
designated as cities e.g Albury, Waga Wagga, Griffith and locations
within their city boundaries are officially "suburbs". The "suburb" with
the same name as the LGA is usually also identified as "city". In
Sydney, some major suburban centres such as Parramatta are identified by
Government as cities. I think the official classification works fairly
well in NSW  and is useful guide for tagging in OSM but not sure about
other states.
 
Then there are areas that have defined boundaries as "suburb" and
designated postcodes but have no permanent population as far as I know
(such as Jagungal Wilderness in NSW or Danggali in SA). Not sure how to
classify them. "Locality" is used for much smaller places that have no
boundaries, postcode or population and seems not the right tag for
larger areas with defined boundaries.
