SydneySydney, New South Wales, is one of the world's great cities, well-organised and well-developed but still very relaxed with several fine green spaces - most notably the cockatoo-frenzied Royal Botanic Gardens.
Australia's main cities are all designed in the same vein: spacious, attractive waterfronts, plenty of greenery and pedestrian-friendly sidewalks but Sydney hit the biggest seam with the world's largest natural harbour - and absolutely gorgeous it is too.
Trivia: the world's second largest harbour? Poole, south England. And by the way, Botany Bay, Captain Cook's first landing point, is an industrial zone about 10kms south of Sydney.
