Right at this moment I'm watching Channel 2 (ABC) which is broadcasting the fireworks display and films of events over the last one hundred years using the Opera House wings as a giant screen for the films.
In Sydney Harbour are 40 warships from various countries along with Prince Harry.
The whole display is to commemorate 100 years since the Royal Australian Navy first sailed into Sydney Harbour.
It's a really fantastic display. Very moving.
Sydney Harbour all lit up like this is truly pretty.
