I'm not sure what areas the Sydney CBD encompasses but I'll assume its the area bounded by Dartling Harbour, The Rocks, Circular Quay, Botanic Gardens through Hyde Park and the Sydney Central Railway Station. Historic buildings, modern high-rise, transport services, monuments, museums, art galleries, the list goes on and all comes together to form a vibrant area in the city. We were lucky to enjoy the area over a seven day period and witness the throngs going about their respective interests, be it tourism, shopping, work or entertainment. Wonderful place to visit.
