Is it true that are the actors from dance academy real dancers based on the following text?

Casting for series one began in early 2009 in Brisbane, Melbourne and Sydney. All cast members had to be skilled in drama and dancing and had to cope with Australia's best choreographers. Filming began on 13 July 2009 and wrapped up in early November. The series premiere was originally planned for a mid-2010 premiere on ABC3, however, like Dead Gorgeous, the premiere was pushed to ABC1 on 31 May 2010 and ABC3 on 6 June 2010. The first series premiered on Germany's ZDF on 26 September 2010.
