It's the first time Australia’s joined in with the Big Dance, which also featured four thousand dancers in London and Glasgow.
The five-minute routine for the event, 'Beats for Peace', was created by Sydney Dance Company artistic director Rafael Bonachela.
Rafael's used to directing the nation's finest dancers - so this project was very different.
He tested it out on his team of office workers, to help him adapt to non-professionals, teaching through community classes and online tutorials.
London Mayor Boris Johnson helped start Big Dance eight years ago in the UK; since then more than two million people have taken part.
