Hi Jimmeyer176
I might have what you are after. We walked the GNW again at the end of last year to update our notes, these distances are since then. You can find info about re-supply options in an earlier post I made with a similar list to this (unfortunately I have done them as two separate lists and don't have time to co-late them right now).
You may notice that the route is a little different to what is on the 6 maps you have, but these are following the GNW as signposted on the ground. These distances also include the two ferry trips (Sydney 4.8km and Brooklyn 8.3km).
Cutting out 'urban' section is a tough question. What is urban to one is wilderness to another, but hopefully you will get a sense of that from this table.
Hope this helps, enjoy the walk
Matt
