“Activity Centres are defined as any place that attracts people for shopping, working, studying, recreation or socializing”. This is a very broad and descriptive definition that is used in Melbourne 2030. The definition was later made more specific in Melbourne @ 5 million, by saying a mixed use centre is where people work, shop, relax, meet friends and family and also live. These centres are usually a reasonable size and are served by public transport of different sizes and intensities (buses, trains, tram and cars cater for most activity centres in Melbourne). This specific definition is meant to be one of the key aspects to Melbourne 2030 Activity Centre Policy being successful in its efforts in the reduction of car dependence.
