This is what we found on Wikipedia regarding the Calisthenics Victoria:

In Australia, calisthenics (also known as Australian calisthenics) is a team-based competitive performing art taking elements of rhythmic gymnastics and ballet combined with a strong emphasis on theatricality (both musical and dramatic), costume, dance and musical interpretation. Since the 1950s Calisthenics has been an entirely female art form, however males have recently been re-introduced in the younger age groups. The art form was created entirely in Australia and can be easily differentiated from traditional calisthenics by its focus on competition and choreographed theatrical performance instead of simple synchronized exercise. The word itself comes from the Greek words for beauty and strength. Calisthenics is currently practiced in all states except Tasmania and has recently been introduced in New Zealand.
