From http://www.castlemaine.org/;

The road to Castlemaine, from Melbourne, passes through towns at roughly equal distance from each other.
The clue to this is given by the first town on the trek from Melbourne being given the name: "Diggers Rest".
Each town is by a water course and is about a days walk from the other .
They were the camp sites for the prospectors as they walked to the gold rush.

Enterprising individuals set up businesses to supply the diggers and of course pubs. That is the origins of these towns.
The trek was 1. Diggers Rest. 2. Gisborne. 3.Woodend. 4. Kyneton. 5. Castlemaine. 6. Bendigo.

Melbourne to Diggers Rest - 35k's

Diggers Rest to Gisbourne - 20k's

Gisbourne to Woodend - 16k's

Kyneton Castlemanine - 37k's

Unless there was some sort or transport service at either end there are some stops missing. Maybe Taradale or Malmsbury at the Castlemaine end and Keilor at the Melbourne end.

From wikipedia (http://en.wikipedia.org/wiki/Keilor)

Keilor in the early times of the gold diggings was a noted camping place for bullock teams to and from the diggins at Castlemaine and Ballarat.

Also from wikipedia (http://en.wikipedia.org/wiki/Malmsbury)

Gold was discovered in 1858 and the town became a service centre for diggers travelling to Bendigo and Castlemaine.

So the trip becomes Melbourne - Keilor - Diggers Rest - Gisoburne - Woodend - Kyneton - Malmsbury - Castlemaine (- Ravenswood? - Bendigo)

As a healthy person can walk between 20-40k's /day (although the definition of a healthy person would be a bit different in the 19th century) depnding on their load, it could be that a bullock train, or a loaded person may stop at each of these places and an unburdened person might make it two stops.

The plan now is to map out Melbourne in relation to this movement and see whether there is any correlation to this scale and the current morphology. What about bicycle scale?
Train? Car? Well they're already somewhat obvious but what happens when you start overlaying them? And what takes the place of the riverside camp? Of course, this all has to relate back to time and how long we are willing to travel in a day.
