[talk-au] OSM Search results return strange stuff for Victoria.

[Jonathon Rossi]

I've not mapped them before but curious now why we don't seem to have
imported addr:postcode tags for suburbs, Nominatim uses them
before centroids.

Surely addr:postcode doesn't have to be unique because it sounds like some
countries have postcodes based on postal routes or other less
administrative boundaries.
