Delahey is a suburb in Melbourne, Victoria, Australia, 20km (10miles) north-west of Melbourne's Central Business District, located within the City of Brimbank local government area. Delahey recorded a population of 8,077 at the 2021 census.
Delahey originally contained several farming properties. The Government acquired the land in the mid-to-late 1980s[1] for re-subdivision as mostly residential properties. The suburb is named after William Delahey, who whilst still a baby, had arrived from Ireland with his parents and siblings Henry Delahey and Mary (née Dodd) in June 1840. William Delahey had been connected with the Keilor Shire Council for 18 years and was elected president for 1882–83. The suburb's name was formally adopted in 1994.
Delahey is the home of the transmitter for the major Melbourne station of the Australian Broadcasting Corporation, 774 ABC Melbourne, with its 215m (705feet) high-guyed transmitter mast.
