Australian Institute of Clinical Hypnosis and Psychotherapy


The Australian Institute of Clinical Hypnosis and Psychotherapy provides training in clinical hypnosis and innovative psychotherapeutic approaches for mental health care professionals.

We aim to provide training that is professional, innovative, refreshing and fun to attend.  The emphasis is on providing a comfortable experiential learning environment and will include teaching, demonstrations and practise.  The acquisition of skills development is incremental to allow participants to build on learning experiences and gaining confidence in the application of these skills in clinical practice with various conditions.


AICHP is a constituent society of the International Society of Hypnosis (ISH).  Completing our 70 hour hypnosis training offer the opportunity to become a member of  ISH.

Our hypnosis training is done in collaboration with the Ericksonian Institute of Sydney Australia (EISA).  EISA is a registered institute with the Ericksonian Foundation in Phoenix, Arizona, USA.
