 The maps used in the report show the CBD as just the Hoddle Grid, plus the parallel streets immediately to the north, and the area between Flinders Street and the river, very similar to the ABS area.Since 1999, the "Melbourne Planning Scheme" has included a 'Capital City Zone' which is a much larger area, including the former CBD, minus the RMIT area, but including Southern Cross Station, much of Southbank down a line along the Westgate Freeway, Kingsway, down to Coventry Street, South Melbourne, and the north wharf area and the South Wharf area.A map of the CCZ can be found here.
