What is the difference between a Clinical Psychologist, Psychologist and a Counsellor/Psychotherapist?

A Clinical Psychologist has completed a minimum of six years study at university and has completed either a Masters or Doctoral degree in Clinical Psychology and have obtained at least two years clinical supervision. Clinical Psychologists have a Clinical endorsement by the psychology registration board of Australia on their registration.

Psychologists have completed a minimum of four years study at university and at least two years of supervised practice.

All Psychologists are registered with the Psychology board of Australia and they must abide by a strict Code of Conduct.

Clinical Psychologists are experts in the study of human behaviour and are able to assess, diagnose and treat people with a wide range of emotional and behavioural problems. Almost anyone can refer to themselves as a counsellor/psychotherapist because their profession is largely unregulated and their qualifications are less easily defined.
