Geelong ( jih-LONG) (Wathawurrung: Djilang/Djalang) is a port city in Victoria, Australia, located at the eastern end of Corio Bay (the smaller western portion of Port Phillip Bay) and the left bank of Barwon River, about 65 km (40 mi) southwest of Melbourne.

As of the 2006 census, 160,000 people resided in 68,000 households. The median age of persons in Geelong was 37 years. About 19.4% of the population of Geelong were children aged between 0–14 years, and 26.6% were persons aged 55 years and over. Each dwelling is on average occupied by 2.59 persons, slightly lower than the state and national averages. The median household income was $901 per week, $121 less than the state average, partly due to higher reliance on manufacturing for employment. The population of Geelong is growing by 2500 people each year, and the City of Greater Geelong had the highest rate of building activity in Victoria outside metropolitan Melbourne.
