History
The area lies in the traditional lands of the Wadandi people.[4]
The name "Wilyabrup" (also spelt "Willyabrup") comes from the local Wilyabrup Brook, which first appeared on planning documents in 1865, and may be derived from "Worlyabaraap", a Noongar word meaning "northern sky".[5]
The area was developed in the 1920s as part of the Group Settlement Scheme, with the construction of a hall beginning in 1922 and a school on the site in 1928; the school was destroyed by fire in 1954.[6][7]
Wine began to be grown there in the 1960s and 1970s, with Vasse Felix and Cullen Wines being the first vineyards in Wilyabrup.[6]
The area was gazetted as a bounded locality in 1987, having previously been a postal district.[5]
