Ellenbrook is a northeastern suburb of Perth, Western Australia, about from Perth's central business district (CBD), located within the City of Swan. Ellenbrook, and its neighbouring suburbs of The Vines and Aveley, are unusual for Perth in being a significant distance from neighbouring suburbs. Given this relative isolation and the distance from the CBD, Ellenbrook has been designed and developed as a self-sustainable community. At June 2018 the estimated urban population for Ellenbrook and surrounds was 41,382. At the time of the 2016 census there were 22,681 people living in the gazetted suburb. It is envisioned that Ellenbrook will eventually become a satellite city, with a population of 80,000.
