St. Johns Anglican Church, Deer Park is of local architectural and historical significance as the oldest wooden church in the Brimbank area, the second oldest Anglican church in the area and was the only church in Deer Park for many years, until the 1960s. It is also of local social significance for its associations with a number of early Deer Park families, including the Christies, Opies, Kingsburys and others. The building of this church was at the height of Melbourne's boom, when development companies were subdividing land in the outer areas of Melbourne and promoting settlement on new estates. St. John's, Deer Park, is symbolic of the Church of England's recognition of the growth of Melbourne and the need to serve those living on the outskirts of the metropolis.
