Sydney enjoyed fireworks displays tonight to mark New Year's Eve on Sydney Harbour.

More than a million people gathered around the harbour as the family fireworks display filled the skies for 10 minutes. It was really great, I loved the colors and the lasers coming off the bridge and children dressed up for the family show, whose theme was The Wonderful Wizard of Oz.

The $4 million New Year's Eve festivities, which have been dubbed a Diamond Night in the Emerald City, also commemorate the Harbour Bridge, which celebrates its 75th birthday in March 2007.

In her New Year's Eve message, Sydney Lord Mayor Clover Moore said the Harbour Bridge symbolized extending the hand of friendship to others at home or to other parts of the world.
