Tourists are drawn to cities by a myriad of attractions and activities. Some cities are blessed with iconic attractions that are on every visitor's "must see" list - the Opera House and Harbour Bridge in Sydney, for example. Other cities rely on a more eclectic mix of "sights and sounds" to lure increasingly well-informed and diverse visitors. For instance, Australia’s second-largest city, Melbourne, has at various times promoted itself as the nation’s "sports and events capital", the "arts and culture capital" and, more recently, as the "street art capital". Street art, also known as graffiti, has not always had strong community support. The proliferation of the "art form" has many strident critics. For example, Graffiti Hurts spokesman Scott Hilditch complained that funding a mobile phone app to guide users around Melbourne street art sites would glorify graffiti vandalism. Yet there is no denying the growth of street art and the popularity of sites around inner-city Melbourne. On a sunny afternoon in the city's laneways, you are likely to see a range of local and international visitors, some posing for photos in front of freshly painted walls, others passing by on their way to a nearby cafe for a flat white.
