The celebrations of the Chinese new year are ongoing until the 12th February! There are a lot of installations and cool things to see. For all the free activities you can have a look at the City of Sydney website. There is everything from lanterns, Lion dances in Chinatown to new year tea ceremonies and Chinese opera performances.
