This study, prepared for the Sydney City Council, analyzed both the economic benefits and costs of the city's nighttime economy. It assessed common data points such as total economic output and employment, as well as less common ones, such as policing and transport costs. The study concluded that the benefits of the nighttime economy to Sydney substantially exceed the negative externalities. Data was primarily obtained through the Australian Bureau of Statistics and Dun & Bradstreet. The study also included a data framework aimed to source reliable future nighttime economic data, policy development recommendations, and a state and federal fiscal impact assessment.
