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?

    Thanks everyone for your input.

    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?

    Cheers
