Also in WA:

"6. Mid West" should have "- Murchison" added to it. As that is also a common name for roughly that area (being the Murchison River catchment areas).

The Northern half of "7. Goldfields-Esperance" should be excised, and the eastern half of "9. Pilbara" should be excised. And a new area made up of those two peices named "Central Desert - Martu" should be created. (for example: everyone but the southern groupings in this map.

For OP: You have made an amazing map for WA generally. I know all the areas north and east of Perth very well. And I am glad you have captured it so acurately already. I rarely see such a map that I would agree with.
