It could be a scene from Downton Abbey. Twelve girls in gowns, gloves and tiaras take the hands of their escorts, curtsey and begin a waltz.
But, despite its candelabras, silk chair covers and white linen, the Novotel in Homebush is a long way from post-Edwardian Yorkshire, and the girls are a long way from Lady Mary Crawley and her fictional Downton Abbey family.
These girls are from Santa Sabina, Strathfield, and the year is 2013.
