[talk-au] Highway route number prefixes for QLD and NT

[Leith Bade]

Hi Mark,

Interesting, I will have a look at that.

We hope in the future to also make use of route relations, however the key
piece of software (osm2pgsql) we use to work with OSM does not support them.

One of my colleagues has been working on a replacement for that software.

Thanks,
Leith Bade
