The rules for dressage are constantly changing. This is to ensure that we, the equestrian riders in Australia, keep up with the rest of the equestrian world. The rules we follow are devised by the FEI (Federation Equestrian Internationale). These are the rules that all Olympic Games and World Championships are run by.
Our governing body in Australia is Equestrian Australia and all dressage events run by Darwin Dressage Club and Alice Springs Dressage Club follow these rules.

It is important that you, as competitors, keep up with the rules that apply to you when competing. They can be found under Rules and Regulations on the national website http://www.equestrian.org.au/
