Sydney has something for everyone to do on January the 26th, Australia Day. Darling Harbour has free entertainment all day. This includes children's entertainment, short films, music from all over the world and the Australia Day Spectacular. Big crowds will attend the Australia Day Spectacular as the Premier and Governor of New South Wales appear, there is a boat parade, concerts and then finally a large fireworks display.
An event called Sample Sydney allows people to visit many of Sydney's famous locations with free, or cheaper than normal, entry prices. Some of the locations open on this day include Government House, Powerhouse Museum, The Mint, Sydney Observatory, Reserve Bank of Australia, Museum of Contemporary Art and the Parliament of NSW.
The biggest Australia Day on Sydney harbour may have been in 1988 for the Australian Bicentenary. On that day, there was a historical re-enactment of the First Fleet arriving in Sydney.
