Darlington, Western Australia, is a locality in the Shire of Mundaring on the Darling Scarp, dissected by Nyaania Creek and north of the Helena River.
Darlington was dissected by the Eastern Railway [1890 - 1954 traffic ceased, 1965/1966 the line was closed and removed] which in later years of operation was known as the 'Mundaring Loop'. Now the Railway Reserve Heritage Trail or 'bridle trail', as it is known by locals, has become a popular walking and bike trail.
Darlington had extensive orchards during the First World War era. It has also, due to its cooler ‘hills climate', had a number of guest houses. D. H. Lawrence stayed in one for a short time during his visit to Australia. Guest houses were also used as convalescent homes during the Second World War period. In the mid twentieth century significant numbers of artists had lived in or been associated with the small community. By the late twentieth century subdivisions of land and the breakup of farms and orchards contributed to an increase in the local population.
Writers, artists and others seeking to be separate from Perth's extensive suburban sand plain had sought the location for its natural surroundings. The artists gained the most publicity for their residence, while the writers and others tended to keep their privacy.
Some of the community groups are over 40 years old. For example, the Darlington Residents and Ratepayers Association evolved from the earlier Darlington Progress Association, the Darlington Arts Festival as well. The tennis, cricket and other sports clubs have similar heritage. A newer arrival, the Darlington Club, is less than two years old and is involved in sustaining community involvement and use of the Darlington Hall.
It is perhaps one of the few 'hills' communities to be served by several primary schools—the Darlington Primary School (State school), Tree-Tops Montessori School, and Helena College. The Darlington Arts Festival, an annual event, has been going for more than 40 years. It includes art exhibitions and other events on the Darlington oval.
The 2006 'Trek the Trail' event was organised on the Railway Reserve Heritage Trail and went from Mundaring to Darlington, and included events on the oval.
The Darlington Review is a monthly publication of some 50 years standing, featuring stories, news, advertisements and other material of local interest. It is one of the few of its kind to serve any hills community for such a long time and is delivered to each address in the locality.
The Mundaring shire council has defined the locality by placing 'Locality of Darlington' signs on its entrance roads at the administrative boundary.
