Cheers Stephen for your input.
One issue that I just noticed is how people expect to read
addresses. In iD editor, the address tags are organised as follows:
Which will lead contributors to add the suburb name in the city tag
as this is usually how we write addresses (e.g. on envelopes), at
least in Queensland.
But anyway, ultimately, if suburb/city/postcode boundaries end up
covering the whole country accurately, I guess most software would
look at those before the individual tags, as Ben explained.
Goodo, thanks everyone!

I have
no strong views on the question regarding the use of
addr:city, in the past I have utilised it in some areas and
not in others as described in your email (sometimes I have put
the suburb in the city tag, as it makes sense in areas, that I
do not know are part of a greater city), due to the lack of
guidance on applicability in Aus.
I am not familar of a current postcode boundary details, I
tend to try and identify this information from what I can
gather in the field, like addresses on menu's/pamphlets from
restaraunts, shops, businesses, or another source is friends
addresses in the area.
Agree that street and housenumber are the required tags, with
others optional.
That is my 2 cents worth.
Stephen.

Re: [talk-au] Address tagging guidelines for Australia
Dear all
Sorry to resend this but I just wanted to have some
feedback on my recommendations about addresses and my
question about the postcodes, if anyone is able to help,
before I add these recommendations to the wiki.
Cheers!

Thanks Ben and Warin for your

So my understanding of it so far is that we could
recommend to tag as follows:
addr:housenumber=separated with semicolons if
several, or range using a hyphen (current general
addressing recommendations)
addr:street=full way name
addr:postcode=four-digit postcode
addr:suburb=suburb name
addr:city=large conurbation (is this the right term?)
e.g. Sydney, Melbourne
addr:state=whole name (as general rule is to make it
as human-readable as possible)
addr:country=AU (country code as currently
recommended)
Housenumber and Street should be pointed out as the most
important bits, as Ben explained. Tags in italic are the
less important ones as they can be deduced from existing
boundaries, and thus ignored to minimise a risk of
confusion or inaccuracies. (?)
I understand from this
page that the suburb boundaries already exist.
About Australian postcodes, the same page says that an
older dataset was removed due to a change in licensing.
Is there any postcode boundary data currently in use for
Australia?
Add:city is a particular case as I understand there is
no official boundaries for those "conurbations" - am I
getting this right, Ben? In that case, should we
recommend users not to use this tag at all as it might
end up being confusing?
Cheers

Hi.
There is an admin
boundary level for local government areas. This is
like a British county.
Note that all
these can be derived for an address simply by
looking where the address node is. Is it inside the
boundary for the country Australia? Then then the
address is in Australia. No need to tag it as well.
Same for suburb/town, LGA and state.
The things you
can't infer from an address's location are the
street number, and which street it is associated
with.
The boundaries for
state and country are well defined. Less so for town
and LGA, but tools like Nominatum will use these
boundaries to describe addresses where they are
present.

Hi.
I think in
Australia, as far as gazetted places go,
suburb=town, but for these, you can derive
it if the suburb has an admin boundary.
City is
not gazetted. E.g. Sydney is a suburb. An
address in nearby Pyrmont is not in Sydney
(the suburb), so saying it is in a city
called Sydney might be confusing.

Perhaps
better to deal with it as a county/shire
issue? As we are british based then this may
be of some assistance?

This should separate any two suburbs of the
same name (I hope!). Unfortunately these are
not in common use here (unlike britain) so may
not be helpful for general navigation.
As for the post office - I'd think they use
the post code first rather than the
city/suburb. I'd think the OS Map is for
navigation, not for the post office? So it
should make sense in a navigational way?

I wonder what was the rationale behind
using abbreviations for countries and
states as I understood that the database
must be as human-readable as possible.
Still, I will be following the
recommendations on the Key:addr page for
addr:country=AU.
However, I am still unsure about suburb
vs city. Key:addr tells us to watch out
for the Australian definition of
suburbs, and Wikipedia says the
following:
"In Australia and New Zealand, suburbs
have become formalised as geographic
subdivisions of a city and are used by
postal services in addressing."
As we are here tagging the address, I
was wondering: are we tagging so the
addresses appear as they should when we
use them (e.g. when we write them on an
envelope) - the original point of
tagging an address I guess - (in which
case I would just go with addr:city=The
Gap), or should we understand the tags
as literally as possible (in that case,
I would go addr:city=Brisbane and
addr:suburb=The Gap).
What would be the best way to decide on
a convention so we can add guidelines
for OSM-AU?
