If you are visiting Sydney you must visit Wollongong, a must see, beaches, lighthouses, this is a wonderful place. There are beautiful restaurants, cafes and beach sidewalks. Look at the Fisherman's Wharf near the lighthouse, surrounded by cannons, take a picnic basket and sit on the grass and enjoy the view, you will never regret it, the children will love it, you can also ride a bicycle. It is really beautiful for children or a romantic day.
