[talk-au] Address tagging guidelines for Australia

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.
