A must see
You can't miss the Sydney Tower's viewing platform if you come to this city. I went to Australia in 1994. I don't remember how much it cost, and in any rate, the price will have changed by now! But whatever it is, I promise you it's worth it. Here you'll have a view of the city that you simply can't get from any other point. You'll really understand the immensity of the city and its great position between the waters of the bay.
