To me your proposed changes appear to be a lot like tagging for the
renderer:

If the states are not doing alphanumeric then they should not be
rendered that way.
I'd suggest linking to the routes you are proposing to change and see
what opinions you get.
I'm sure this has been discussed before and I think the general
consensus was "only tag with alphanumerics where it is signposted as such".
You may also want to have a look at these:
https://en.wikipedia.org/wiki/List_of_road_routes_in_Queensland
There is a similar wikipedia page for each state.

Hi,
I work for Mapbox as their only southern hemisphere contractor based
in Canberra.
Recently we begun a project to enhance our maps with highway shield
images.
Most of Australia has been fairly straightforward to develop shield
selection rules for thanks to the alphanumeric system.
However there are a states where no prefix is used with numeral only
routes. Particularly Queensland (which has a mix of numeral and
alphanumeric systems due to ongoing transition), the Northern
Territory, and West Australia (which have not adopted the alphanumeric
yet).
In other states prefixes are used to separate National Highways (green
and gold shields), National Routes (white shields) and State Routes
(blue shields).
Notably in Melbourne a "S xx" and West Australia a "Sxx" prefix is
used for blue shield routes. Also in Tasmania "NH1" is used for the
only non-alphanumeric route.
For national consistency I would like to change all state routes in
the Northern Territory and Queensland to use a "Sxx" prefix.
Additionally in West Australia and Northern Territory to change all
national highways to "NHxx" prefix.
There is no use of a prefix currently anywhere for a national route,
however changing the few remaining routes in West Australia, Northern
Territory and Queensland to use a "NRxx" prefix would be useful.
Finally I found state route 24 in Northern Territory is highway=trunk
when at most it should be highway=primary to match the rest of the
state. Also in Queensland national route 1 from Cairns heading out
west is also trunk when at most it should be primary since it does not
connect to a major city.
I welcome any feedback or suggestions.
Thanks,
Leith Bade
