Distant icons and city skyscrapers

Sydney centre became a distant view as we neared the actual entrance to the harbour 11km away with the rugged sandstone cliffs of North Head and South Head flanking the gateway to the ocean. We went round to middle harbour and saw the numerous suburbs and beaches along the way. It was so surprising how huge the harbour actually is, apparently if you walked all the way from North Head around the edge of the whole harbour back to South Head then it is the equivalent distance as from Sydney to Brisbane!! I can’t find out if this is exactly true, but anyway, it gives you an idea of the scale of the whole thing.
