There are many Hypnosis-related bodies/groups in Australia such as the Australian Society of Hypnosis (ASH) & the Australian Hypnosis Association (AHA), however within Australia there is no one governing body. This is because the Hypnotherapy industry is currently deregulated.
In order to join the ASH, you need to have a degree as one of the following: Chiropractors, Dentists, Medical Practitioners, Midwives, Nurses, Occupational Therapists, Optometrists, Osteopaths, Physiotherapists, Podiatrists, Psychologists, Social Workers & Speech Pathologists.
In order to join the AHA, you need to have completed the minimum required 600 hours of training as well as holding a current First Aid Certificate; Malpractice Insurance and a police clearance check.
Other bodies/groups within Australian are the Australian Society of Clinical Hypnotherapists (ASCH), the Professional Clinical Hypnotherapists of Australia (PCHA), the Australian Association of Clinical Hypnotherapy & Psychotherapy (AACHP), the Council of Clinical Hypnotherapists (CCH), and the Hypnotherapy Council of Australia (HCA).
So as you can see, there are many bodies/groups that you could choose to join, each with different membership requirements, however you are not required to become a member of any of these groups/bodies in order to practice Hypnosis in the public arena.
After completing our Hypnosis Training course successfully, you are entitled to call yourself a Practitioner of Hypnotherapy, or a Hypnotherapist. Australian Success Academy provides additional training opportunities, taking your skills to a more advanced level, however these are not essential to practice Hypnotherapy (although, they are highly recommended).
As with any skill, the more training and experience you receive the more competent you will become in working with people in a professional capacity.
