My children love to play in the circular fountain in the Darling Harbour. I like the buskers performing and just watching people from different parts of the world taking a stroll, talking, eating, having fun. It's a joy to see how much people can get along with each other if the venue and weather is right.
I like to attend the events on days like Australia Day. There's also the SEA LIFE Sydney Aquarium, WILD LIFE Sydney and Madam Tussauds up past the bridge. Tumbalong Park hosts a lot of events and festivals and there's the Chinese Gardens and the Maritime Museum.
