The "Toodyay valley" name has been used to refer to the full stretch of the valley as a potential agricultural zone,[1][2][3] for co-operative ventures.
[4] The term was in use earlier in agricultural co-operative ventures[5] as well as anecdotal histories of local inhabitants.
[7][8] The term used in the late twentieth century was "Avon Valley" to include the towns of York, Northam and Toodyay.
[9] Originally "Old Toodyay" or "West Toodyay" was the western end of the valley, with the eastern limits of Newcastle (as Toodyay was originally known) marking the eastern end of the valley.
The river and Eastern Railway enter the valley from the east, and move through to the west towards the Avon Valley National Park.
