The Holy Monastery of Saint John is a coenobitic monastic community for men (a monastic brotherhood that stresses community life) under the Greek Orthodox Archdiocese of Australia in the Archdiocesan District of Perth.  The Monastery is located in Forrestfield, a suburb at the outskirts of Perth where the picturesque Darling Range begins, a low escarpment running north-south to the east of the Swan Coastal Plain and Perth, Western Australia.

Its idyllic location together with the large parcel of land it occupies both contribute to a monastic life of quietness and prayer, whereas its proximity to the metropolitan area of Perth allows for regular contact with the faithful and spiritual enrichment.
