In Australia all Psychologists must complete 4 years of undergraduate study in human behaviour at university. From 2022 new psychologists are also required to complete a one year Professional master degree before they can apply for registration as a psychologist. 

All Psychologists must register with the Australian Health Practitioners Regulation Agency (AHPRA) and adhere to strict ethical and professional standards and that they remain up to date with the most recent advances in the treatment of psychological conditions through ongoing training and professional development.

Psychologists may then complete further specialised training at a postgraduate level (i.e., 2 year Masters or 3 or 4 year Doctorate degrees). Once completed they may apply for an Area of Practice Endorsement (AoPE) with AHPRA.  AoPE identifies psychologists who have completed an approved postgraduate qualification and supervised training in an area of practice, and who can use a protected title associated with that area of practice. These titles include Clinical Psychology, Counselling Psychology and Educational and Developmental Psychology.

Clinical Psychology training is focused on the assessment, diagnosis and treatment of mental illnesses and complex psychological problems. Clinical Psychologists are therefore specialists in the application of psychological theories and scientific research to solve complex psychological problems and to develop individually tailored interventions for mental health disorders.

Counselling psychology addresses the emotional, social, work, school and physical health concerns people may have at different stages in their lives, focusing on typical life stresses and more severe issues with which people may struggle as individuals and as a part of families, groups and organisations. Counselling psychologists help people with physical, emotional and mental health issues improve their sense of well‐being, alleviate feelings of distress and resolve crises.

Educational and Developmental Psychologists work with people of all ages to understand and support their growth. They address issues related to development and conduct assessments to determine people are tracking developmentally.

Unlike psychologists, there is no requirement to be registered with any governing body in order to practice as a counsellor or therapist and there is no legislation which limits the use of these titles. This means that the practice of counsellors and therapists may not be monitored to ensure that it adheres to certain ethical and professional standards.

Psychiatrists are medical professionals with general medical training who have specialised in mental health, in the same way that other medical professionals may specialise in various forms of surgery or in general practice. Psychiatrists therefore specialise in prescribing medication which can assist in managing mental illnesses. Psychologists and psychiatrists often work together to provide comprehensive management and support for complex mental health issues.

Speech pathologists are university trained professionals who work with people of all ages to diagnose, manage and treat speech, language, fluency, swallowing and voice difficulties. 
They may assist with social skills, reading and communication skills including alternative forms of communication such as assistive technology. 

Occupational therapists often work with children and adolescents to help them achieve their daily occupations that may include self-care, school and play. By focussing on these key areas, OTs help children in developing confidence, self-esteem, social skills and general wellbeing.
